Golang Testing Standards

Priority: P0 (CRITICAL)

Principles

  • •Table-Driven Tests: The idiomatic way to write tests in Go.
  • •Subtests (t.Run): Run table entries as subtests for better reporting.
  • •Parallel Usage: Use t.Parallel() for independent tests to speed up execution.
  • •Mock Interfaces: Mock at the boundaries (interfaces).

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.
