Software testing services that plug into your sprint
Most QA vendors test after your team ships and hand defects back on their own schedule. GoGreenlit’s QA engineers join your sprint itself: writing test cases in planning, executing them alongside development, and filing defects before a release goes out, not after.
Every layer
Testing across every layer, not just the UI
We test the interface your users touch, the APIs and data pipelines behind it, and the cross-browser and regression coverage that keeps a release from breaking something that used to work. None of it happens in a separate cycle bolted onto the end of a sprint.
- Test cases get written in sprint planning, not after the code is done.
- Execution happens alongside development, sprint by sprint.
- Coverage and findings get reported in your own standups.
- Defects are filed and triaged before a release ships, not discovered after.
Services
Every service your product’s testing pyramid needs
From hands-on manual sessions to automated suites running in your CI, each engagement is scoped around your stack and your release cadence, not a fixed package.
Manual testing
Hands-on exploratory sessions, user acceptance testing, and usability review, testing the product the way your actual customers will use it, not a scripted checklist.
Playwright automation
TypeScript end-to-end suites checked into your repository, covering multiple browsers, and wired into your CI so a failing test blocks a bad merge instead of a bad release.
Selenium testing
Enterprise automation frameworks built on the Page Object Model, with parallel execution, for teams that already depend on a Selenium suite and need it extended, not rebuilt.
API and data testing
Contract testing for REST and GraphQL endpoints, plus validation of the ETL jobs and data pipelines that never show up in a UI test but break production just as often.
QA strategy and process
Risk-based test planning, a testing pyramid sized to your stack, and sprint-level coverage metrics that show where your actual exposure is, not a generic audit.
Regression testing
Automated regression triggered on every pull request and every deployment, risk-prioritized so the checks that matter most run first.
Mobile testing
iOS and Android testing across real device and OS combinations, covering functionality, compatibility, and performance before a build reaches the app store.
Not sure where to start?
Most teams begin with one service and add more as the need shows up.
Playwright or Selenium?
Choose the tool that fits your stack, not the trend
Playwright is our default for new suites. If your team already runs Selenium, we extend it instead of rewriting it for its own sake.
Modern web apps
Playwright
Fast, reliable, and built for the way modern front ends behave. Our default for new automation work.
A good fit when
- Your app is React, Vue, or similar
- You want traces and video on every failure
- You run tests in CI on every pull request
import { test, expect } from "@playwright/test"; test("coupon applies once", async ({ page }) => { await page.goto("/cart"); await page.getByLabel("Coupon").fill("WELCOME"); await page.getByRole("button", { name: "Apply" }).click(); await expect(page.getByTestId("discount")).toHaveCount(1);});Established stacks
Selenium
Mature, widely supported, and the right call when a large suite already works and your team knows it. We extend it rather than force a rewrite.
A good fit when
- You already have a Selenium suite
- You need broad language support
- Your grid and tooling are already in place
WebDriver driver = new ChromeDriver();driver.get(baseUrl + "/cart"); driver.findElement(By.id("coupon")).sendKeys("WELCOME");driver.findElement(By.id("apply")).click(); assertEquals(1, driver .findElements(By.className("discount")).size());driver.quit();How we work
How we work inside your sprint
Shift-left by default
Test cases get written in sprint planning and smoke tests run pre-merge, so a defect gets caught before it is merged, not after it is shipped.
Embedded in your ceremonies
Your QA engineer sits in standups and retros like any other engineer on the team, not a vendor waiting on a status update.
Coverage you can actually see
We track functional test execution, pass rates, and production escapes, the metrics that predict a bad release, not a code coverage percentage that does not.
95%
Proof
Release coverage achieved on a real engagement.
Coverage is a number you can read, not a feeling. See how an embedded engagement got there in the 95 percent coverage case study.
Mobile app testing
Pick a device. See the checks.
- Face ID and passcode flows
- Dynamic Island and safe areas
- Low power mode behavior
- Offline and weak signal
- Back gesture and system navigation
- Notch and punch-hole layouts
- Background kill and restore
- Permission prompts
- Split view and rotation
- Large-screen layouts
- Keyboard and trackpad input
- Multitasking states
Your stack
Built to test the stack you already run
Your QA engineer adapts to the stack you already have, not the other way around. A sample of what we test against regularly:
- Frontend
- React, Next.js, Vue, Angular, and server-rendered apps
- Backend
- Node.js, Python, Java, and Go APIs
- Databases
- PostgreSQL, MySQL, MongoDB, and Redis
- Infrastructure
- AWS, GCP, and Azure
- Testing tools
- Playwright, Selenium, Postman, REST Assured, PyTest, and Appium
- CI/CD
- GitHub Actions, Jenkins, GitLab CI, and CircleCI
