Table Tests, Subtests & Helpers | Go Tutorial #29

Learn unit testing in Go! Go's built-in testing package makes it easy to write reliable, maintainable tests without any external dependencies. In this lesson, we build tests from scratch covering four key patterns every Go developer should know. What you'll learn: - Writing test functions with func TestX(t *testing.T) - Test file naming convention (_test.go) - Running tests with go test -v - Table-driven tests - the Go community standard pattern - Subtests with t.Run() for organized, named test cases - Running specific tests with the -run flag - Test helpers with t.Helper() for clean error reporting - TestMain for setup/teardown across test suites - t.Skip() for conditionally skipping tests Source code: https://github.com/GoCelesteAI/go_testing Timestamps: 0:00 - Introduction 0:30 - Test Basics 3:45 - Table-Driven Tests 6:35 - Subtests with t.Run 10:10 - Test Helpers, TestMain & t.Skip 14:00 - Recap 14:30 - Up Next Testing is a first-class citizen in Go - no extra frameworks needed!
