Does it follow my project's specific folder structure?

Absolutely. TestGen analyzes your directory patterns to determine whether tests should be co-located with source files, placed in a __tests__ folder, or stored in a separate tests/ directory.

Can TestGen detect my existing testing framework?

Yes, it scans configuration files like package.json, pyproject.toml, and go.mod to automatically identify and use your project's preferred testing library such as Vitest, Mocha, or Pytest.

Which programming languages does TestGen support?

TestGen supports a wide range of languages including TypeScript/JavaScript, Python, Go, Rust, PHP, and Bash, with specialized experts for frameworks like React and Vue.

How does TestGen handle E2E testing?

TestGen includes specialized routing for Cypress and Playwright, and can even utilize Chrome DevTools MCP for visual regression testing if requested.

Can I control the thoroughness of the generated tests?

Yes, you can specify depth levels like 'quick', 'normal', or 'thorough' and focus areas such as 'happy path', 'edge cases', or 'error handling' to match your specific needs.
