Test automation services
Test automation services: end-to-end suites in Playwright, Selenium, Cypress and WebdriverIO, API and component tests, automation frameworks built or repaired, SDET work inside your development team, and suites wired into CI so every change is tested before it ships, with dedicated test automation engineers for your team or automation projects delivered end to end.
Test automation we build
End-to-end suites in Playwright
Browser tests in TypeScript, Python, Java or C# across Chromium, Firefox and WebKit, with fixtures, page objects, network mocking where a third party is slow, and a trace of each failure that replays it step by step.
Selenium and WebdriverIO frameworks
Selenium suites in Java, C# or Python kept running and moved to WebDriver BiDi, Selenium Grid on Kubernetes or a cloud grid, and WebdriverIO where one JavaScript framework tests both the web app and the mobile app.
Cypress suites
End-to-end and component tests in Cypress for JavaScript front ends, with custom commands, intercepted network calls, and parallel runs recorded in Cypress Cloud or in your own reports.
CI integration and parallel runs
Suites that run on every pull request in GitHub Actions, GitLab CI, Azure Pipelines or Jenkins, sharded across machines so they finish in minutes, with Allure or HTML reports, traces and videos attached to the build.
Tests below the user interface
Most checks written as unit, component and API tests in xUnit, JUnit, pytest, Vitest or Jest that run in seconds, so the slower browser suite covers only the journeys that need a browser.
SDET work in your team
An SDET who joins your developers to build the framework, test data factories and environment set-up, review the tests in each pull request and make testability part of every design.
Flaky test repair
Unstable tests found from the run history and fixed at the cause, such as fixed waits, shared test data or a dependence on test order, or deleted, with a quarantine meanwhile so a red build means a real failure.
Test data and environments
Synthetic test data generated for each run, databases seeded and reset between tests, and an ephemeral environment for each pull request, so no test depends on what an earlier run left behind.
Visual regression testing
Screenshot comparison in Playwright, Percy, Applitools or Chromatic for the pages and components where layout matters, with dates and other changing content masked so they do not fail the build.
Hire test automation engineers
Dedicated test automation engineers
Test automation engineers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Test automation projects
A defined piece of test automation with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.
Ongoing test automation
Test automation as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

How we automate tests
Automation follows the test pyramid: most checks run as unit, component and API tests that finish in seconds, and the browser suite covers the journeys users depend on, such as sign-up, search and payment. Tests live in the same repository as the code, are reviewed in the same pull requests, and run against a real database in a container rather than a mock.
A failing test blocks the merge or the release, and a failure that is not a bug is treated as a defect in the suite: fixed at its cause or removed, never retried until it happens to pass. On a suite another team wrote, we start with a read-only review of its run history, flaky tests and coverage, and a written list of risks in order of impact.

Questions about test automation
Which industries do your test automation engineers work in?
Mostly e-commerce and retail, where search, cart and checkout run through automated suites on every release; fintech and banking, with payment and account flows tested on each change and the results kept as evidence; enterprise SaaS and ERP products with many roles and integrations; healthcare platforms; AI and data products; and media and consumer apps that ship every week.
Playwright, Selenium or Cypress?
Playwright for most new web suites: it drives Chromium, Firefox and WebKit from TypeScript, Python, Java or C#, runs tests in parallel and keeps a trace of each failure for replay. Selenium where a suite already exists or a grid of real browsers is needed, and WebdriverIO where one framework should drive both web and mobile through Appium. Cypress for JavaScript front ends whose developers already know it. An existing suite is repaired rather than rewritten unless a rewrite costs less.
Do you use AI to write tests?
Yes, to draft them. Playwright’s test agents and coding assistants turn a test plan into a first version of the tests, and an engineer reviews each one, checks that it fails when the feature is broken, and only then adds it to the suite.
How quickly can test automation engineers start?
When the right test automation engineer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire test automation engineers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Want your tests automated?
Tell us your stack, how you release today and which checks you run by hand. You get an answer within one business day: an automation plan, candidate profiles, or a scope for a review of your current suite.
