Professional Go developers know that testing is not optional—it’s a fundamental skill that ensures your applications scale safely and reliably. In this course, you’ll dive into Go’s standard testing library (testing package), learning how to write clean, table-driven unit tests that are concise and maintainable. You’ll extend your skills with third-party libraries like testify for assertions and mocks, ensuring you can test both pure functions and complex systems with external dependencies.
We’ll also cover advanced strategies such as benchmarking for performance, fuzz testing for unpredictable input, and integration testing with temporary databases and file systems. You’ll discover how to apply Test-Driven Development (TDD)—writing tests before code—to drive cleaner design and reduce bugs. Along the way, you’ll integrate code coverage analysis, CI/CD pipelines for automated testing, and explore golden files for snapshot testing.
By the end of the course, you’ll not only write reliable, production-grade tests but also build the discipline of using tests as a tool to design, document, and safeguard your Go applications.
