Mastering Testing in Go: Best Practices
- Testing is crucial for reliable software, and Go paired with GoFr framework offers powerful tools for streamlined testing workflows.
- GoFr enhances testing benefits by providing unified mocking, declarative expectations, built-in HTTP testing utilities, and cross-service dependency management.
- Embracing Table-Driven Tests in Go allows validating multiple scenarios with clear separation of test setup and assertions.
- Leveraging Dependency Injection via Context in GoFr helps isolate components for true unit testing with easy mock configuration.
- Isolating tests with fresh instances in GoFr prevents test pollution between cases by initializing new app instances per test.
- Testing edge cases and failure modes in GoFr ensures resilience under real-world conditions, including scenarios like database failures and network timeouts.
- Avoiding global state in testing ensures determinism and reproducibility, exemplified by GoFr's containerized approach for clean resource handling.
- Validating HTTP contracts in GoFr ensures API spec compliance through tests covering HTTP status codes, response headers, JSON schema, and error formats.
- Benchmarking critical paths in GoFr helps identify performance bottlenecks early, such as database query performance and concurrent request handling.
- GoFr testing features include unified mock container, declarative expectations, HTTP service mocking, automatic validation, and contextual logging for efficient testing.
