Test automation services: senior SDETs who build suites you trust
Senior automation engineers who build Playwright, Cypress, Appium and API test suites in your repos, wire them into CI, and keep them fast and free of flaky failures.
By the Ryz Labs team · Updated October 2026
Ryz test automation services give you senior automation engineers (SDETs) who build end-to-end, API and component test suites in your repos, run them in your CI pipeline on every pull request, and keep them fast and stable. They come from the top 1% of the engineers we interview and work on US business hours, so a red build gets investigated the same day. The goal is a suite your developers trust enough to merge on, not a dashboard of thousands of tests nobody believes.
What we build
- End-to-end web suites: Playwright or Cypress tests for critical user journeys such as signup, checkout, approvals and settings, written with page objects or fixtures your developers can read.
- API test suites: pytest, REST Assured, Karate or Supertest suites that cover contracts, auth rules and error paths, which run in seconds and catch most back-end regressions.
- Mobile automation: Appium, Espresso, XCUITest or Detox suites running on emulators in CI and on real devices through BrowserStack or Sauce Labs.
- Contract tests: Pact consumer-driven contracts between services, so a breaking API change fails before it reaches staging.
- Component and visual tests: Testing Library, Storybook interaction tests and visual comparison with Chromatic or Percy for UI changes.
- CI integration: parallelized, sharded test jobs in GitHub Actions, GitLab CI, Jenkins or Azure Pipelines, with retries reported, not hidden, and artifacts such as traces, videos and logs on failure.
- Test data and environments: factories, seed scripts, API-based setup and ephemeral environments with Docker Compose or Testcontainers so tests do not share state.
- Migration of legacy suites: moving brittle Selenium or record-and-playback suites to Playwright or Cypress, keeping the tests that matter and deleting the rest.
How an engagement works
Talk. We review your current tests, CI setup, release cadence and where regressions come from, and agree on which flows must never break.
Match. We propose automation engineers who write code in your language (TypeScript, Java, Python, C# or Kotlin) and know your framework and CI system.
Join. Engineers work in your repos and pipelines, review pull requests with your developers and join standups and retros.
Grow. Extend coverage to mobile, performance or contract testing, or train your developers to own the framework and scale the automation team down.
Week 1 typically covers an audit of existing tests, flake rates and CI run times, and a list of the highest-value journeys to automate. By month 1, a framework with conventions is merged, the first critical-path tests run on every pull request, and failure artifacts make debugging fast. By month 3, the usual picture is broad API coverage, end-to-end tests on the top journeys, a tracked flake rate, and a pipeline time that developers accept.
The stack our teams work in
| Layer | Tools we use | Notes |
|---|
| Web end-to-end | Playwright, Cypress, Selenium WebDriver, WebdriverIO | Playwright is our default for new suites; we work in what you have. |
| API | pytest, REST Assured, Karate, Supertest, Postman/Newman | The largest share of automated checks usually lives here. |
| Mobile | Appium, Espresso, XCUITest, Detox, Maestro | Native frameworks for speed, Appium for cross-platform. |
| Unit and component | Jest, Vitest, JUnit 5, Testing Library, Storybook | Written with developers, close to the code. |
| Contracts and visual | Pact, Chromatic, Percy, Applitools | Catch API and UI breakage early. |
| CI and infrastructure | GitHub Actions, GitLab CI, Jenkins, Azure Pipelines, Docker, Testcontainers | Sharded runs, cached dependencies, isolated environments. |
| Reporting | Allure, Playwright HTML reports, Currents, Datadog CI Visibility | Flake tracking and trends per test. |
How we keep test suites fast and trustworthy
Test automation projects usually fail the same way. The suite grows, gets slow, starts failing at random, and developers learn to rerun until it goes green. At that point it is a cost, not a safety net. Our engineers design against that from the start:
- The right layer for each check. Most logic is tested at unit and API level, where tests are fast and precise. End-to-end tests cover only the journeys that need a real browser. Ten good UI tests beat five hundred brittle ones.
- No fixed sleeps. Tests wait on state, using Playwright auto-waiting, web-first assertions and network idle checks, never a hard-coded timeout.
- Stable selectors. data-testid attributes or accessible roles agreed with developers, not CSS paths that break on a redesign.
- Independent tests. Each test creates its own data through APIs and cleans up, so tests can run in parallel and in any order.
- Flakes quarantined and fixed. Flaky tests are tagged, moved out of the blocking path and tracked to a root cause, such as a race condition, shared data or an unstable environment. Some of those turn out to be real product bugs.
- A pipeline time budget. The team agrees on a target for pull-request checks and holds it with sharding, test selection by changed files and moving slow suites to nightly runs.
- Failures you can debug. Every failed run keeps traces, screenshots, video and logs, so a developer can see what happened without rerunning locally.
- Developers own tests too. Automation engineers set the framework and patterns, then pair with developers so new features ship with tests written by the people who built them.
Team shapes and cost
Typical Ryz cost is $7,000 to $15,000 per engineer per month. Mid-level engineers are $7,000 to $10,000, senior engineers are $10,000 to $15,000, and leads are $15,000 or more, quoted per team.
- One senior SDET: 1 × $10,000 to $15,000 = $10,000 to $15,000 per month. Fits a team that needs a framework set up and patterns established.
- Automation pair: 2 senior SDETs × $10,000 to $15,000 = $20,000 to $30,000 per month. Fits web plus API coverage, or web plus mobile.
- Quality engineering team: a QA lead ($15,000+) plus 3 senior SDETs ($30,000 to $45,000) = from $45,000 per month. Fits several products or a large legacy-suite migration.
Every quote is scoped per team. You get a plan, a price and the names of the people before you start.
Dedicated team or staff augmentation?
With staff augmentation, automation engineers join your squads and build tests alongside your developers. This works best when you want automation to become part of how your team works. See profiles on our hire QA automation engineers page and a sample QA automation engineer job description.
A dedicated development team fits a defined project, such as migrating a large Selenium suite or building automation for a new platform, delivered and handed over with documentation. Ryz engineers work on your team, reporting to your leads, in both models.
When Ryz isn't the right fit
If you want a codeless, record-and-playback testing product rather than engineers, a tool vendor is the better call. If you need an hourly freelancer to write a handful of scripts, a freelance marketplace is quicker. If your engineering team works on European or Asian hours, a global network will give you better overlap.

FAQ
Which test automation framework should we use?
For new web suites we usually recommend Playwright for its auto-waiting, parallelism and trace viewer. Cypress is a good fit if your team already uses it. For mobile, native Espresso and XCUITest are fastest, and Appium covers both platforms with one codebase. We work in what you have when it is serving you.
How much do test automation services cost?
Typical cost is $7,000 to $15,000 per engineer per month. One senior SDET is $10,000 to $15,000 per month, and two are $20,000 to $30,000 per month. Total cost is team size × duration × monthly rate.
How fast can automation work start?
After the scoping call we propose engineers with names. Most of the timeline depends on scope and on your onboarding, especially access to repos, CI and test environments.
Our current suite is flaky. Should we start over?
Rarely all at once. We measure which tests fail randomly and why, quarantine the worst, fix the root causes and migrate the valuable tests to a better framework while the rest keep running.
Will automation replace our manual QA?
No. Automation covers repetitive checks on stable flows. Exploratory testing of new features still finds bugs scripts miss. Our QA testing services cover that side.
