golang-testing

Table-driven tests in Golang use named subtests to ensure clarity and determinism. You define test cases in a struct slice and iterate over them, executing subtests with t.Run to isolate failures and maintain fast, readable test suites.

Goroutine leaks in Go integration tests are detected using goleak. You integrate goleak verification in TestMain to ensure tests do not leave lingering goroutines, guaranteeing deterministic and safe test suite execution.

Testify mocks for Go unit testing allow you to define expected method calls and return values on mock objects. This isolates dependencies and ensures fast, maintainable unit tests without relying on external services.

Yes, this approach supports fuzzing and benchmarking in Go projects. It specifies clear patterns for writing benchmarks and fuzzing tests to evaluate performance and uncover edge-case vulnerabilities, ensuring production-ready code.

Yes, you can run parallel tests safely in Go by calling t.Parallel within subtests. Following structured parallel testing patterns ensures fast execution speeds while avoiding data races and maintaining test determinism.
