FAQ

Why switch to Tester H?

Because it transforms how teams approach end-to-end testing. Tester H enables full end-to-end test automation using simple natural language instructions, powered by a visual-linguistic model (VLM) combined with a smart web agent. By adopting Tester H, you drastically reduce the time spent writing and maintaining test scripts, while significantly increasing coverage across critical user flows. The system adapts to UI changes, proactively detects and alerts for both functional and visual bugs, and helps you secure each release with minimal effort. It’s built for teams that want to move faster and release with confidence, without being weighed down by traditional QA overhead.

Can I integrate Tester H into my existing QA stack?

Yes. Tester H fits smoothly into your existing QA stack. You can export test scripts in Playwright, Selenium and Python (and JavaScript support is coming soon), and run them directly within your CI/CD pipelines using GitHub Actions, GitLab CI, Jenkins and more. TesterH also supports environment variables, custom hooks, and cron-based scheduled runs.

Do I need to know how to code to use Tester H?

Not at all. Tester H is designed for both manual QA testers and automation engineers. You can generate robust end-to-end tests directly from natural language prompts (including Gherkin-style Given/When/Then). The generated scripts follow best practices, so your QA team can easily review, adapt, extend, or run them as-is with full confidence.

Can Tester H handle real-world, complex applications?

Yes. Tester H is built to automate real user flows across modern, dynamic web applications, including multi-step forms, auth flows, pop-ups, modals, mobile responsiveness, and async content. The AI agent interprets functional intent and generates reliable, maintainable test scripts that are ready for execution or further customization.

The AI Agent Made for Testing

Tester H transforms the way you validate user journeys combining instant execution, intelligent automation, and zero-code simplicity into a fast, accurate, and seamless testing experience.
