Golang Testing Standards

Priority: P0 (CRITICAL)

Principles

Guidelines

TDD Workflow

1. Red: Write a failing table-driven test case.
2. Green: Implement logic to pass.
3. Refactor: Simplify code.

Golden Snippet

See Table-Driven Tests for full template.

Tools

• Stdlib: testing package is usually enough.
• Testify (stretchr/testify): Assertions (assert, require) and Mocks.
• Mockery: Auto-generate mocks for interfaces.
• GoMock: Another popular mocking framework.

Naming

• Test file: *_test.go
• Test function: func TestName(t *testing.T)
• Example function: func ExampleName()

Anti-Patterns

• Sleeping in tests: Use channels/waitgroups or retry logic.
• Testing implementation details: Test public behavior/interface.
