Working with Go Modules and Testing
Manage real dependencies with go.mod, then write table-driven tests, benchmarks, and fuzz tests that actually catch bugs.
Prerequisites: Build a REST API in Go, or an existing Go module with at least one function to test.
Version note: verified against current docs as of July 2026, targeting the common Go 1.25/1.26 feature set.
go test needs no separate framework, runner, or config file — any function named TestXxx(t *testing.T) in a _test.go file is discovered and run automatically. This project adds a real dependency to a module, then builds out unit tests, table-driven tests, a benchmark, and a fuzz test against the items API from the previous project.
