Table-driven tests in Go use struct slices to define scenarios, running each as a named subtest for clear output and scalable execution. This approach enforces observable-behavior testing and simplifies adding edge cases.

Detect goroutine leaks in Go tests by integrating goleak to verify concurrent code cleanup. It automatically checks that goroutines terminate properly after test execution, preventing hidden resource exhaustion.

Separate integration tests from unit tests in Go by applying build tags and TestMain setup. This structurally isolates slower, dependency-heavy tests from fast unit tests, ensuring maintainable test suites.

You can use testify to implement assertion helpers and mocks within your Go test suite. This ensures tests remain maintainable and focus on observable behavior rather than internal implementation details.

This Go testing approach applies to projects of any size, automating best practices for fast and reliable unit and integration tests. It scales from basic table-driven scenarios to complex integration patterns.
