golang-testing

Golang table-driven tests use struct slices to define cases, executing them via subtests for structured coverage. This pattern iterates multiple inputs and expected outputs, simplifying test maintenance.

Starting TDD with Go testing involves applying the Red-Green-Refactor cycle. You write failing tests first, implement code to pass, and refactor to ensure high test coverage and code reliability.

Fuzzing for Go API handler validation works by automatically generating random inputs to discover security vulnerabilities and edge cases. It provides robust input validation by feeding unexpected data to functions.

You can run performance benchmarks and race detection together in Go. Benchmarking templates measure execution time for critical code, while race detection identifies concurrent synchronization issues.

Golden files in Go tests store expected output data for your test suite to compare against actual function results. This comparison ensures code reliability when generating complex outputs like reports.
