Software Testing Services
goGreenlit provides embedded software testing services for startups and growing engineering teams. We test every sprint, track coverage, and file defects before your users find them – not after.
Software testing is not one thing. A well-built QA function covers multiple layers: the UI, the API, the data pipelines, the cross-browser edge cases, the regression risk, and the features your users actually care about. goGreenlit provides coverage across all of it – choosing the right tool for each layer rather than applying the same technique to every problem.
Our testing services are designed for teams that ship on a regular cadence and need QA that keeps up. We don't run waterfall test cycles. We test inside agile sprints: writing test cases in sprint planning, executing during the sprint, reporting in standup, and filing defects while there is still time to fix them before the release.
Exploratory testing, UAT, smoke testing, and usability review. The human judgment layer that catches what automated scripts cannot.
View service →TypeScript end-to-end test suites built with Playwright – cross-browser, parallel, and integrated into your CI/CD pipeline from day one.
View service →Enterprise Selenium frameworks with Page Object Model architecture, parallel execution, and full CI integration for Java and Python stacks.
View service →REST, GraphQL, and contract testing – plus data integrity validation for ETL pipelines and database-driven features.
View service →Build a testing process that fits your team: risk models, testing pyramids, sprint integration, and metrics that tell you where you actually stand.
View service →Functional QA, cross-browser compatibility, responsive design validation, and accessibility checks for web applications.
View service →Regression suites that scale with your codebase – automated, prioritized by risk, and running on every deploy without falling behind.
View service →iOS and Android QA: functional testing, device compatibility, upgrade path validation, and performance checks on real devices and emulators.
View service →Most outsourced testing operates outside the development process. Tickets go in, results come back, and nobody is quite sure what got tested. We built goGreenlit specifically to not work that way.
We start from a shift-left model: quality checks happen earlier in the cycle, before the cost of fixing problems escalates. That means participating in sprint planning to identify testing scope, writing test cases before implementation starts, and running smoke tests on pull requests before they merge to main.
Sprint-embedded means we are in your standup, your retrospective, and your defect triage. You know what we tested. You know what we found. You know what is in the backlog. There are no surprises at release time.
Coverage-driven means we track metrics over time. Not lines of code covered by automated tests – that number is nearly meaningless in isolation. We track functional coverage: what percentage of your defined test cases were executed, what percentage passed, and what escaped to production despite test coverage. Those numbers tell you something real.
We work across the modern web and mobile stack. On the frontend: React, Next.js, Vue, Angular, and server-rendered applications. On the backend: Node.js, Python, Java, and Go APIs. For databases: PostgreSQL, MySQL, MongoDB, and Redis. For infrastructure: AWS, GCP, and Azure environments.
For test tooling: Playwright, Selenium WebDriver, Postman, REST Assured, PyTest, Cypress (migration assessment), and Appium for mobile. For CI/CD: GitHub Actions, Jenkins, GitLab CI, and CircleCI.
If your stack isn't on this list, ask. We have enough breadth to adapt to most environments.
Not sure which services you need? A 30-minute discovery call is enough to figure out the right starting point. We'll ask about your current testing situation and give you an honest recommendation – even if the answer is something we don't offer.
Everything you need to know about our software testing services.
Our outsourced software testing covers manual testing, regression testing, API testing, and test automation depending on what your product needs. We embed directly into your existing sprint cycle, attend standups, and work inside your tools rather than asking you to adapt to ours.
Most teams are actively contributing within 5 to 7 business days of signing. By day 7, we are writing test cases, flagging bugs in your tracker, and participating in sprint ceremonies alongside your developers.
Manual testing involves a QA engineer executing test cases by hand, which is essential for exploratory testing, usability checks, and any scenario that requires human judgment. Automated testing uses frameworks like Playwright or Selenium to run repeatable test scripts at scale. The most effective QA programs run both in parallel.
We build automation with Playwright and Selenium. Playwright is our default recommendation for new projects. If you already have an existing Selenium suite, we can maintain and extend it rather than rebuilding from scratch.
Yes. API testing is one of our core service areas. We validate REST and GraphQL endpoints for correctness, security edge cases, error handling, and contract compliance. For microservices architectures, we cover service boundaries and integration points.
Regression testing verifies that new code changes have not broken existing functionality. For most SaaS teams shipping weekly or bi-weekly, we recommend automated regression on every pull request and a full manual regression pass before each production release.
Escaped defects happen when QA is rushed or missing from the sprint. By embedding a dedicated QA engineer inside your sprint cycle, we make testing continuous. Teams see an average 45% reduction in escaped defects within the first 90 days.
After signing, we schedule a 30-minute kickoff, review existing test documentation, set up access to your tools, and join the next sprint ceremony. Most teams are surprised by how little disruption the ramp-up causes.
Every engagement starts with a conversation. Tell us what you're building, how you ship, and where quality is currently breaking down.
