testing

Table-driven tests in Go use t.Run to execute subtests for each scenario, applying testify's assert and require to validate outcomes. This structure cleanly covers multiple test cases while maintaining reliable execution and reducing boilerplate.

Real database integration tests in Go exercise actual DB interactions without mocks to prevent flaky results. You manage test databases and environment state using TestMain setup and teardown guidance to ensure reliable end-to-end verification.

TestMain setup and teardown manages Go test databases by initializing the environment before tests run and cleaning it up afterward. This ensures real database integration tests execute against a reliable, isolated state without requiring mocks.

This canonical testing approach applies to Go-based backends requiring reliable end-to-end testing with real databases. It enforces non-mocking tests, table-driven patterns, and clear organization using t.Run and testify across packages.

Avoiding mocking in Go end-to-end tests prevents flaky, inaccurate results by exercising actual database interactions. Canonical testing practices enforce real DB verification to guarantee your service behaves correctly under true integration conditions.

Organize Go test cases across packages by following clear conventions for test structure and naming. This canonical testing skill provides guidance on test organization, dependencies, and lifecycle management to standardize practices and reduce boilerplate.
