To write table-driven tests, define a slice of test case structs and loop through them using t.Run to execute named subtests. This pattern improves test readability, isolates failures, and allows running cases in parallel.

Detect goroutine leaks in Go tests by integrating goleak to verify all background goroutines terminate cleanly. This reduces test flakiness and ensures observable behavior across integration tests.

Structure Go integration tests using build tags to isolate slow tests from fast unit tests. This separation aligns with CI workflows and keeps local development fast by excluding integration suites by default.

Use testify mocks to simulate external dependencies and verify observable behavior rather than internal implementation details. This approach produces deterministic tests that remain robust during refactoring.

Yes, you can use example functions in go-testing to compile executable documentation. These examples verify output correctness during CI and automatically generate reference snippets in Go package documentation.
