Lesson 1 · Tutorial · Go 1.21+

Testing in Go: Table Tests, HTTP, Fakes, and Coverage

Write effective Go tests with table-driven cases, subtests, httptest, fakes, race detection, benchmarks, and useful coverage.

Read tutorial Lesson 2 · Tutorial · Go 1.21+

Writing Unit Tests in Go: A Practical Guide

Write golang unit tests that catch bugs: test structure, error checks, table cases, fakes, injected clocks, and coverage, with real go test output.

Read tutorial Lesson 3 · Tutorial · Go 1.22+

Table-Driven Tests in Go: The Idiomatic Way

Golang table driven tests done right: subtests with t.Run, parallel cases, error tables with errors.Is, and golden files, with real tested output.

Read tutorial Lesson 4 · Tutorial · Go 1.24+ (b.Loop); the b.N form works on Go 1.7+

Go Benchmarking: Measuring Performance with testing.B

Learn Go benchmarking with testing.B: read ns/op, B/op and allocs/op, avoid the dead-code trap, use b.Loop, and compare implementations you can trust.

Read tutorial Lesson 5 · Tutorial · Go 1.21+ (stdlib examples tested on Go 1.24.7)

Mocking in Go: Test Doubles Without Magic

Learn golang mocking the idiomatic way: small interfaces plus hand-written fakes, spies, and httptest, with generated mocks only when they earn it.

Read tutorial Lesson 6 · Tutorial · Go 1.22+

Integration Testing in Go: Testing Real Boundaries

Write Go integration tests that hit real boundaries: HTTP with httptest, a real Postgres, plus build tags and -short to keep go test ./... fast.

Read tutorial Lesson 7 · Tutorial · Go 1.18+

Fuzz Testing in Go: Finding Bugs Automatically

Learn golang fuzz testing with the native toolchain: write a FuzzXxx target, run go test -fuzz, and watch the engine find a real bug end to end.
