Go Testing Patterns

Comprehensive Go testing patterns for writing reliable, maintainable tests following TDD methodology.

When to Activate

• Writing new Go functions or methods
• Adding test coverage to existing code
• Creating benchmarks for performance-critical code
• Implementing fuzz tests for input validation
• Following TDD workflow in Go projects
• Structuring table-driven tests for a function with many input variations or edge cases
• Setting up golden file tests for functions that produce formatted text or structured output
• Debugging a test that fails intermittently due to parallel subtest variable capture or shared state
