go-testing

Table-driven tests in Go use a slice of structs to define test cases, iterating through them with t.Run to create subtests. This pattern improves test reliability and readability by separating test data from test logic.

Go test files should end with _test.go and reside in the same package directory. Using TestMain for setup and t.Parallel for concurrent execution ensures proper test organization and faster, more reliable testing cycles.

Go benchmarks and fuzz tests use the standard testing package to validate performance and find edge cases. You define BenchmarkXxx and FuzzXxx functions to execute repeated runs and identify unexpected input vulnerabilities.

Yes, t.Run creates subtests for isolated execution, and t.Parallel signals that a subtest can run concurrently with other parallel tests. Using both ensures faster test execution while maintaining strict test isolation.
