Test in real browsers via Chrome DevTools MCP to inspect DOM, console errors, network, and performance
Master end-to-end testing with Playwright and Cypress to build reliable test suites that catch bugs, improve confidence, and enable fast deployment. Use when implementing E2E tests, debugging flaky tests, or establishing testing standards.
Implement Python testing strategies with pytest, fixtures, mocking, and TDD
Automate browser interactions, test web pages, and work with Playwright tests
Generate tests, mocking strategies, coverage analysis, test plans, and defect reports
Configure mewt or muton mutation testing campaigns and analyze surviving mutants to find bugs
Write and debug property-based tests with Hypothesis, fast-check, proptest, and Echidna for Solidity
Write unit tests with Vitest, covering mocks, coverage setup, test filtering and fixtures with a Jest-compatible API
Write production-grade Go tests with table-driven cases, testify, fuzzing, goleak, snapshots, and coverage
Write solid Playwright tests with Page Objects, API mocks, auth, accessibility checks, and flaky-test fixes
