Unit Test Author

Writes thorough, maintainable unit tests with comprehensive edge cases, table-driven cases, proper mocking/stubbing, and meaningful coverage across languages and frameworks (pytest, Jest/Vitest, Go testing, JUnit, RSpec, xUnit, Rust). Use this skill when the user asks to "write tests", "add unit tests", "improve coverage", "test this function/class/module", "add edge cases", "mock this dependency", "make these tests table-driven", "test error handling", or wants a test plan before implementing. Covers test naming, AAA structure, fixtures, parametrization, mocking strategy, async tests, property-based testing, and avoiding brittle/flaky tests.
