Table-driven tests in Go use a struct slice to define multiple input scenarios and expected outputs, executing subtests iteratively. This Skill guides you through structuring test cases and running assertions to verify function behavior across various conditions systematically.

Mocking in Go unit tests uses interfaces to stub external dependencies like database calls. This Skill demonstrates how to isolate components by replacing real implementations with mock objects, ensuring focused and reliable testing of specific handlers.

Fuzz testing in Go automatically generates random inputs to uncover edge cases and potential panics in code logic. This Skill provides examples of writing fuzz tests to ensure robustness by validating function behavior against unexpected input data.

TDD workflow supports developing a new API endpoint by writing failing tests before implementation. This Skill guides you through the Red-Green-Refactor cycle to structure HTTP handler tests, mock dependencies, and ensure endpoints behave correctly under various conditions.

Benchmarking Go code measures execution time and memory allocations using the testing package. This Skill covers writing benchmark functions to evaluate performance bottlenecks and ensure code reliability during intensive operations.
