TL;DR
Product engineering testing services combine test strategy, automation, and specialist QA capacity so software quality is built into every release instead of checked at the end. The right partner extends your engineering team rather than replacing its judgment, and the strongest setups pair internal product ownership with a partner’s automation depth.

AI-Powered QE: The Key to Faster, Better Product Development
Kanerika’s on-demand session on how AI-assisted quality engineering shortens release cycles without cutting corners on coverage.
Watch the Webinar → Key Takeaways Product engineering testing services embed quality checks across the entire product lifecycle, not just a final release gate before launch. Shift-left testing and QAOps move defect discovery earlier, which cuts the cost of fixes that would otherwise surface in production. AI-assisted testing is now mainstream, with 61 percent of organizations using it across most workflows, but integration, not budget, is the real adoption barrier. The strongest operating model is usually hybrid, pairing internal product knowledge and release authority with a partner’s automation depth and specialist capacity. Kanerika builds QA and test engineering into its product engineering delivery model, with clients seeing delivery cycles move up to 65 percent faster. A faster release cadence does not automatically buy better quality Most engineering leaders do not go looking for a testing partner. They arrive at the search after something else breaks first. A release slips because the QA queue cannot clear in time. A customer-facing bug reaches production during a renewal quarter. A new platform launch reveals that nobody actually owns performance or security testing.
Software teams have gotten faster at building. Sprints are shorter, deployments are more frequent, and AI-assisted coding tools have pushed code output higher across most engineering organizations. Testing capacity has not kept pace with any of that.
Legacy modernization projects add another layer of pressure. A team moving off an aging platform, covered in Kanerika’s guide to application modernization trends , has to prove the new system behaves the same way the old one did before it can safely cut over, which is its own dedicated testing problem separate from ongoing feature work.
Product engineering testing services exist to close that gap. Done well, they are not a bolt-on QA vendor that reviews finished work. They are a testing function woven into planning, architecture, build, release, and production, so quality becomes a property of how teams engineer the product rather than a checkpoint at the end of it.

40% More Efficient Geolocation Testing for a Construction Software Platform
Kanerika automated geolocation testing for a construction-management platform’s web and mobile applications, cutting testing errors by 30%, lifting overall productivity by 25%, and reducing time-to-market by 20%.
Read the Case Study → What product engineering testing services actually cover Product engineering testing services are the combination of test strategy, manual and automated testing, quality engineering, and release validation applied across a product’s full engineering lifecycle rather than a single release. According to ISTQB’s definition , software testing assesses quality and reduces the risk of failure in operation. Product engineering testing extends that idea across every stage a product moves through, not just the code that ships this sprint.
The distinction from traditional QA matters more than it sounds. Traditional QA often means a team that receives a build near the end of a cycle and checks it against requirements. Product engineering testing means a team that is present earlier, understands the product’s architecture and roadmap, and treats every release as one data point in a longer pattern of risk. That distinction is easiest to see in custom software development engagements, where the same team building the product owns its quality bar from the first sprint instead of a separate QA vendor discovering the architecture for the first time weeks before launch.
Traditional QA vs. product engineering testing Traditional QA Product engineering testing Final-stage defect checking Continuous quality engineering across the lifecycle Test execution against a defined build Test strategy tied to product architecture and roadmap Manual scripts, run per release Automated pipelines integrated into CI/CD Release sign-off Lifecycle risk control, including production feedback Reported in defect counts Reported against product and business outcomes
A capable testing partner takes on test strategy, environment planning, test data, automation engineering, defect management, and release recommendations. What should stay with the client is product priorities, business requirements, risk tolerance, and final release authority. A good engagement never asks a client to hand over that last part.
Where testing fits across the product engineering lifecycle Testing is often treated as a phase that happens after development. In a mature product engineering model, it shows up at every stage.
Planning and requirements. Acceptance criteria review, risk analysis, and testability assessment before a single line of code is written.Architecture and design. Threat modeling, performance risk review, and API contract checks while the system is still on a whiteboard.Development and CI. Unit tests, static analysis, and automated build verification run on every commit and pull request.Integration testing. End-to-end workflows, service integrations, and third-party API behavior validated together, not in isolation.Release validation. Regression, performance, security, and compatibility checks that gate whether a build is ready to ship.Production. Synthetic monitoring, canary releases, and real-user error tracking that feed defects back into the next planning cycle.Each stage catches a different class of problem. Skip one, and the gap does not disappear. It shows up later, more expensive, and closer to a customer.
The full scope of product engineering testing services A capable testing partner brings depth across a wide set of disciplines. Not every product needs all of them, but a partner who can only offer one or two is not a product engineering testing partner, just a manual test vendor.
Functional and regression testing Functional testing confirms features behave the way the product should work, covering business rules, user workflows, and edge cases. Regression testing re-runs that coverage after every change, so a fix in one area does not quietly break another. Risk-based regression, where test selection is tied to what actually changed in the code, keeps this fast instead of ballooning with every release.
Test automation engineering Automation is a discipline, not a checkbox. A mature automation practice designs frameworks around the product’s architecture and prioritizes stable and high-risk workflows first. It treats flaky tests as a maintenance debt to pay down, not a normal cost of doing business. Not everything belongs in automation. Frequently changing features, one-off tests, and subjective usability checks are usually better left manual.
Case Study
74% Less Testing Time for a Connected-Vehicle Telemetry Platform
Kanerika’s automation-driven testing cut testing time by 74%, reduced infrastructure-related issues by 45%, and increased customer satisfaction by 32% for a connected-vehicle telemetry analytics platform, while lifting platform scalability by 30%.
Read the Case Study → API and integration testing Modern products are built from services talking to each other. API testing validates request and response behavior, schema contracts, authentication, and error handling, while integration testing confirms that services, third-party dependencies, and event-driven systems behave correctly together, not just individually.
Performance and load testing Performance engineering is broader than running a load script before launch. It covers baseline, load, stress, spike, and endurance testing, plus how the system behaves under sustained real-world traffic. The metrics that matter go beyond a single average response time, including response time percentiles, throughput, error rate under load, and database query time. For customer-facing products, these performance targets increasingly line up with Google’s Core Web Vitals , which turned loading speed and responsiveness into metrics that affect both user experience and search ranking.
Security testing Security testing spans static and dynamic application security testing, dependency scanning, authentication and session testing, and penetration testing. Automated scans catch a real class of issues, but they do not replace a human security assessment. The OWASP Testing Guide remains one of the clearest frameworks for what a thorough security testing program should include, and it is worth holding any partner’s security testing scope up against it. Kanerika’s own data security best practices guide and AI security framework cover the adjacent controls that security testing should be validated against, particularly for products handling regulated or sensitive data. Teams building a formal security testing program often map it against NIST’s Secure Software Development Framework , which sets baseline practices for reducing vulnerabilities across the development lifecycle rather than only at release.
Mobile, browser, and compatibility testing Products that span devices, operating systems, and browsers need testing across that whole matrix, not just the primary platform. This includes device fragmentation, network conditions, battery and memory use, and backward compatibility as new versions ship.
Accessibility and usability testing Accessibility testing checks a product against standards like the W3C Web Content Accessibility Guidelines , covering keyboard navigation, screen reader support, color contrast, and focus order. Usability testing looks at whether real users can complete tasks without friction, which automated checks alone cannot tell you.
Data, cloud, and reliability testing Data-heavy products need testing for transformation logic, migration accuracy, and referential integrity. Cloud-native products need testing for auto-scaling, resilience, and disaster recovery, including failure injection and regional failover drills. Together these confirm a product survives the conditions it will actually run under, not just a clean demo environment. Data pipeline validation follows many of the same principles covered in Kanerika’s guide to data migration testing , where reconciliation and referential checks catch problems before they reach a downstream report, and the same discipline applies whether the pipeline runs on Databricks , Snowflake , or a custom data analytics stack.
User acceptance testing and exploratory testing UAT confirms the product actually solves the business problem it was built for, which is a different question from whether it meets a written specification. A capable partner plans UAT scenarios with the business, coordinates the users who need to sign off, and tracks defects through to resolution rather than treating it as a formality before launch.
Exploratory testing fills the gap that scripted cases miss. A tester investigating a new feature without a fixed script tends to surface the visual defects, unexpected workflows, and confusing error states that a checklist was never written to catch. This matters even more for AI-generated features, where the code was not written by a person who can explain every branch of logic by hand.
Kanerika Service
Product Engineering Services
Kanerika designs, builds, and tests digital products end to end, with QA and test engineering built into the same delivery team as design and development.
Explore Product Engineering Testing requirements change with the type of product you’re building A generic test plan applied to every product misses the risks that are specific to how that product is actually built and sold. The testing priorities for a multi-tenant SaaS platform are not the same as the priorities for a data-heavy enterprise system or an AI-enabled feature.
SaaS and multi-tenant products SaaS testing has to account for tenant isolation, subscription plan differences, usage limits, and feature flags that change what a given customer sees. A defect that only appears for one tenant configuration is easy to miss in a single-tenant test environment, and expensive when it reaches a paying customer’s account.
Enterprise software Enterprise products carry customer-specific configurations, complex identity and permission systems, and integrations that vary by client. Testing has to cover that configuration surface directly, not just the default installation, because the default installation is rarely what a large customer is actually running.
API-first and platform products When the product is a platform other developers build on, contract stability and versioning become testing priorities in their own right. A breaking API change that was never flagged in testing does not just cause an internal bug. It breaks every downstream integration that depends on that contract.
AI-enabled products Testing a product that uses AI is a different discipline from using AI to test a product. Probabilistic outputs mean a test cannot always assert a single correct answer. Instead, testing has to evaluate output quality, groundedness, consistency across repeated runs, and failure modes like hallucination or prompt injection, alongside the privacy and data handling questions that come with any AI feature built on customer data. Teams building AI features, generative AI features, or agentic AI workflows into a product need this evaluation layer designed alongside the feature itself, not added after the first customer complaint about an inconsistent answer.
Shift-left testing means finding problems earlier, not doing less testing Shift-left testing moves quality checks earlier in the development process, so teams test requirements, designs, code, APIs, and integrations before full system testing begins. It is one of the more commonly misunderstood ideas in modern QA, partly because the name suggests a shortcut.
Shift-left does not mean eliminating system testing later in the cycle. It does not mean developers become the only testers, or that teams automate every test regardless of whether that makes sense. It also does not remove the need for production monitoring after release.
Development stage Shift-left testing activity Requirements Acceptance criteria and risk review Design Testability and threat assessment Coding Unit, component, and static analysis checks Build Automated API and integration checks Deployment Environment and configuration validation
The other half of the equation is shift-right, where production telemetry, synthetic tests, and real incident data feed back into the next cycle of test planning. Teams that only shift left still miss the defects that only show up under real traffic.
QAOps brings testing into the same pipeline as everything else QAOps is the practice of integrating quality processes, automation, environments, and reporting directly into the CI/CD pipeline, the same way DevOps integrated operations into delivery. It does not replace developers or QA engineers. It changes where their work sits relative to the release process.
In a working QAOps model, some checks are strict quality gates that block a release outright, such as a critical security finding, a failed core workflow, or a contract-breaking API change. Other checks, like a minor visual difference or a low-impact accessibility issue, should inform the team without stopping the pipeline. Confusing the two is one of the fastest ways to make a release process either too slow or too risky.
Test environment and test data management sit underneath all of this. On-demand environments, data masking, and production-like scale are what let a QAOps pipeline actually run continuously instead of waiting on a shared staging environment that five teams are fighting over.
Where AI actually fits into testing in 2026 AI in testing has moved past the experimentation phase for most organizations, but adoption and results are not the same thing. BrowserStack’s State of AI in Software Testing 2026 report, based on a survey of more than 250 engineering and QA leaders, found that 61 percent of organizations already use AI across most of their testing workflows. The same report found that 37 percent of teams cite integrating AI tools with existing workflows as their top challenge, well ahead of budget concerns. For most teams, the barrier is operational, not financial.
Traditional automation AI-assisted testing Runs predefined scripts Can propose or generate test cases Relies on fixed locators Can adapt to some interface changes Executes the full defined suite Can rank and select tests by risk Requires manual maintenance Can assist with test maintenance Reports raw failures Can group failures and suggest root causes
The practical use cases worth paying attention to include AI-generated test cases from requirements and self-healing automation that adapts to minor UI changes. Also useful: risk-based test selection that cuts regression run time, and AI-assisted defect analysis that groups related failures instead of leaving a team to triage a hundred red builds one at a time.
Where AI helps and where it still falls short There are real limits here too. Generated tests still need human review before a team can trust them. Self-healing automation that silently adapts to a broken workflow can hide a real defect instead of catching one. And testing AI-enabled products themselves, where outputs are probabilistic rather than deterministic, is a different discipline from using AI to test conventional software. Before trusting a vendor’s AI testing claims, it is worth asking directly which tasks are actually AI-assisted, whether generated tests are reviewed before they run, and what evidence backs any claimed time savings.

Scoping AI-Assisted Testing for Your Product?
Kanerika can walk through which parts of your test suite are ready for AI assistance today and which still need a human oracle.
Schedule a Demo → In-house testing versus outsourced testing Factor In-house testing Outsourced testing Product knowledge Usually stronger from day one Must be actively transferred Specialist access Limited by local hiring Broader specialist bench Scaling for peak releases Slower, tied to headcount Faster, capacity can flex Cost structure Mostly fixed Variable or outcome-based Independence of assessment Can be lower Can provide an outside view
In-house testing is the stronger fit when a product carries highly sensitive intellectual property, product knowledge takes years to build, and demand for testing is stable and predictable. Outsourced testing earns its place when release demand fluctuates, specialist skills like performance or security testing are needed on and off, or automation debt has piled up faster than internal teams can address it.
The strongest setup in practice is rarely all one or the other. A hybrid model, where internal teams keep product knowledge and release authority while a partner supplies automation depth and specialist testing capacity, tends to outperform either extreme. It keeps context inside the organization while adding the capacity and skills that are expensive to build and maintain internally.
Engagement models for product testing services Not every product needs the same relationship with a testing partner. The right model depends on how much control you want to keep, how predictable your testing demand is, and how mature your internal QA leadership already is.
Five ways to structure the engagement QA staff augmentation. External testers work inside your team under your daily direction. Best when internal QA leadership is strong and the gap is a defined skill or headcount shortage. This is the same staff augmentation model used across broader engineering hiring, applied specifically to testing roles.Project-based testing. A fixed scope tied to a specific release, migration, or launch, with a clear start and end date.Managed testing services. The partner owns agreed testing processes, staffing, tools, and reporting against defined service levels. Best when testing demand is recurring across multiple products. The trade-offs here mirror the ones covered in staff augmentation versus managed services , just scoped to QA instead of full delivery teams.QAOps as a service. A partner builds and operates continuous testing inside your CI/CD pipeline, combining automation, environments, and quality gates. Best for DevOps-heavy teams releasing frequently.Testing Center of Excellence support. Standards, frameworks, and reusable automation assets shared across multiple product teams to keep quality practices consistent at scale.A useful shortcut when narrowing this down is to match the model to your organizational condition. A strong internal QA leader with a capacity shortage usually points to staff augmentation. A weak internal testing function with recurring demand usually points to managed testing. A DevOps-mature team with slow pipelines usually points to QAOps as a service. The broader question of whether to staff up or outsource entirely is covered in more depth in staff augmentation versus outsourcing , and the same logic applies whether the team in question is building features or testing them.
Kanerika Service
IT Staff Augmentation for QA Capacity
Kanerika supplies testers, automation engineers, and specialists who plug into your existing team and release cadence.
See How Staff Augmentation Works What product engineering testing services actually cost There is no single hourly rate that answers this honestly, because cost depends on product complexity, platform count, release frequency, existing automation maturity, and how many integrations and environments are in play.
People and roles. Manual testers, automation engineers, and specialists in performance or security carry different rates and different scarcity.Automation setup. Framework design, initial script development, and CI/CD integration are usually a larger upfront cost than the ongoing execution.Environments and data. Test environment provisioning, test data creation, and data masking for privacy compliance are recurring costs that are easy to underestimate.Tooling. Automation platforms, performance testing tools, and security scanning licenses add up, whether the client or the provider funds them.Ongoing maintenance. Automation suites decay as the product changes. Flaky test repair and suite maintenance are real, continuing costs, not a one-time setup fee.One-time costs buyers commonly miss include knowledge transfer, initial framework setup, and security approval for provider access. Ongoing costs commonly missed include automation maintenance, staff turnover on the provider side, and the cost of production defects that testing did not catch. A useful way to frame the full picture is to add people, tools, environments, data, management overhead, and the cost of defects that reach production, rather than comparing providers on a single hourly figure.
The cheapest proposal on paper is often the most expensive one over a year, usually because it hides a junior-heavy team, thin automation design, or incomplete test coverage that only becomes visible after a few production incidents.

Cracking the Code: Engineering Strategies for Rapid Product Launches
A practical look at how engineering and QA teams compress launch timelines without raising release risk.
Watch the Webinar → Common mistakes companies make when bringing in testing help Treating testing as a headcount problem. Adding testers without an automation strategy just moves the bottleneck instead of removing it.Handing over release authority along with test execution. Product priorities and risk tolerance should stay with the client, even in a fully managed engagement.Comparing proposals on hourly rate alone. A proposal that only lists tester counts and rates, without a test strategy, is not a serious proposal.Skipping knowledge transfer. A partner who does not understand the product’s architecture and history will re-discover the same edge cases your team already knows about.Automating the wrong things first. Automating a feature that changes every sprint burns effort maintaining tests that break as fast as they are written.No exit plan. Automation assets, test documentation, and defect history should belong to the client, not disappear if the engagement ends.How to choose a product engineering testing partner Start with your product’s risk profile, not the vendor’s service list. Identify your critical workflows, security exposure, and release frequency before you evaluate anyone.Ask for evidence of product engineering experience, not just testing experience. Long-lived SaaS platforms, multi-tenant systems, and repeated release cycles are a different challenge than a one-time project, and a firm built around product engineering as a discipline tends to bring more of that context than a pure test-execution vendor.Examine the proposed test strategy in detail. It should name specific risks, test levels, environments, automation scope, and reporting, not just a headcount and a rate card.Check automation engineering depth. Ask how they design frameworks, how they decide what to automate first, and how they handle flaky tests.Confirm what stays under your control. Release authority, business acceptance, and product roadmap decisions should never transfer to the partner.Weigh location and delivery model. Nearshore and offshore testing teams both work, but time zone overlap and communication cadence should match how tightly your release process needs to run.Ask how a transition would work if the engagement ends. Asset ownership and documentation quality tell you more about a vendor’s discipline than their sales pitch does. The same due diligence that applies when you hire dedicated developers applies here, since a testing team is being handed just as much product context.Real proof points matter more than a features list. Ask any partner for examples from their own case study archive that resemble your product’s scale and complexity, not just a generic list of testing services offered.
Not every question on that checklist has an obvious answer without a conversation.

Evaluating a Testing Partner?
Kanerika can walk through your product’s risk profile and test strategy before you commit to an engagement model.
Schedule a Demo → How Kanerika approaches product engineering testing Kanerika treats testing as a built-in part of product engineering , not a separate function bolted on after delivery. QA and test engineering is one of six pillars in Kanerika’s product engineering practice, alongside product design and architecture, application modernization, cloud engineering, full-stack development, and DevOps and platform engineering. The same teams that design and build a product are accountable for validating it.
That structure follows a consistent delivery pattern across engagements. In the assess stage, Kanerika’s engineers evaluate the product’s architecture, identify testing gaps, and align coverage priorities with business risk rather than a generic checklist. In the design and build stage, automation frameworks get built around the product’s actual workflows. For a construction-technology client, that meant a behavior-driven framework using Serenity BDD and Cucumber, with test scenarios written in Gherkin so both engineers and non-technical stakeholders could read and sign off on them before automation started. Kanerika scopes performance and load testing to real traffic patterns instead of guesswork. In the operate stage, continuous quality validation runs inside the client’s CI/CD pipeline, with monitoring and defect feedback looping back into the next planning cycle.
Case Study
90% Faster Releases: Automated Testing for a Digital Construction Platform
Kanerika built a unified Serenity BDD and Cucumber testing framework for a digital construction-delivery platform, cutting pipeline execution time by 60%, accelerating product releases by 90%, and reducing overall costs by 30%.
Read the Case Study → Results from Kanerika’s testing engagements The construction-platform engagement above is not an outlier. On a related engagement for a construction-management platform built on geolocation data, Kanerika’s automated geolocation testing framework cut testing errors by 30 percent, lifted overall testing productivity by 25 percent, and shortened time-to-market by 20 percent.
Across Kanerika’s broader product engineering engagements, clients have seen delivery cycles move up to 65 percent faster and engineering costs drop by up to 40 percent. Fintech and healthtech products have reached market up to 50 percent faster. Both patterns trace back to the same root cause: automated test coverage built in from the start, not bolted on after a product is already struggling with defect leakage.
The practical lesson from that pattern holds regardless of who does the testing. Automation debt and thin regression coverage rarely announce themselves. They show up as slower releases and more late-cycle firefighting, months after the choices that caused them were made. Building testing into product engineering from the start, rather than treating it as a phase to catch up on later, is what keeps that pattern from repeating, whether that capacity comes through technology staff augmentation or a fully managed engagement.
Kanerika also supports the engagement models covered above through IT staff augmentation and engineering outsourcing arrangements, so testing capacity can flex with a client’s release calendar rather than staying fixed regardless of demand. For teams building on a Microsoft or cloud-native stack, testing plans typically fold in the same controls used across Kanerika’s data governance engagements, so a product’s quality controls and its data controls are not designed by two teams that never talk to each other. Testing capacity itself can be sourced the same way as any other role, including through offshore staff augmentation when a client needs broader time zone coverage.
Common testing pitfalls to watch for The pitfalls Kanerika’s engineering teams watch for most often are not exotic. Automation suites that were never designed for maintainability, security testing that gets treated as a once-a-year audit instead of a continuous practice, and performance testing that only runs against a staging environment nobody has sized to match production traffic.
Two more show up just as often. Flaky tests that get re-run until they pass, or quietly skipped, instead of being fixed or removed. Once a team stops trusting its own test suite, engineers fall back on manual spot-checks before every release, which is the exact outcome test automation was supposed to prevent. And chasing a coverage percentage as if it were the goal: a suite with high statement coverage on low-risk code tells a team less than a smaller suite focused on the handful of workflows where a failure actually costs money.
Each of those is fixable, but only if someone is looking for them before a release, not after a customer reports the outcome.
Wrapping up Product engineering testing services work best when teams treat them as part of how a product gets built, not a gate it passes through before launch. The specific mix of functional, automation, performance, and security testing will vary by product, but the operating principle does not. Teams should plan quality early, test it continuously, and own it jointly between a client’s product team and whichever partner supplies the extra capacity. Get that ownership split right, and the engagement model, tooling, and cost conversations become much easier to settle.
Frequently Asked Questions What are product engineering testing services? Product engineering testing services combine test strategy, manual and automated testing, and quality engineering applied across a product’s full lifecycle, from planning through production. They cover functional, automation, performance, security, and compatibility testing, delivered by a partner who understands the product’s architecture rather than just executing a fixed test script.
Is product engineering testing the same as QA? They overlap but are not identical. Traditional QA often means checking a finished build against requirements near the end of a release. Product engineering testing is broader, spanning requirements review, architecture risk assessment, continuous automation, and production monitoring, treated as part of how the product gets engineered rather than a final gate.
Should I keep testing in-house or outsource it? It depends on how sensitive the product’s intellectual property is, how stable testing demand is, and whether specialist skills like performance or security testing are needed only occasionally. Most organizations do best with a hybrid model, keeping product knowledge and release authority internal while a partner supplies automation depth and flexible capacity.
What is shift-left testing? Shift-left testing moves quality checks earlier in development, so requirements, designs, code, and APIs get tested before full system testing begins. It does not replace system testing or production monitoring. It reduces the number of defects that would otherwise be found late, when they are more expensive to fix.
How much do product engineering testing services cost? Cost depends on product complexity, platform count, release frequency, and existing automation maturity, so there is no single hourly rate that applies everywhere. A realistic estimate adds people, tools, environments, test data, management overhead, and the cost of defects that reach production, rather than comparing providers on rate alone.
What is QAOps? QAOps is the practice of integrating quality processes, automation, environments, and reporting directly into a CI/CD pipeline, similar to how DevOps integrated operations into delivery. It does not replace developers or QA engineers. It changes where testing work sits relative to the release process, making some checks automatic release gates.
How is AI changing software testing in 2026? AI is now used across most testing workflows at a majority of organizations, particularly for generating test cases, prioritizing regression runs, and grouping related failures. Integration with existing workflows, not budget, is the main adoption barrier most teams report. Generated tests and self-healing automation still need human review before they can be trusted.
What engagement models are available for testing services? Common models include QA staff augmentation, where testers join a client-managed team, project-based testing tied to a specific release, managed testing services where a partner owns the process end to end, and QAOps as a service, where a partner builds and operates continuous testing inside a client’s CI/CD pipeline.
