This package implements a functionality for testing socket and HTTP servers in Golang.

Package stub provides helper functions to replace global variables for testing, and restore them afterwards.

Package st, pronounced ghost, is a tiny test framework for making short, useful assertions in your Go tests. Assert(t, have, want) and Refute(t, have, want) abort a test immediately with t.Fatal. Expect(t, have, want) and Reject(t, have, want) allow a test to continue, reporting failure at the end with t.Error. They print nice error messages, preserving the order of have (actual result) before want (expected result) to minimize confusion.

Ginkgo is a Behaviour-Driven Development testing framework for Go. It builds on top of Go's builtin testing library and is complemented by the Gomega matcher library.

go-snaps is a Go implementation of Jest snapshot testing.

This package implements a parallel testing framework for Go.

Package gunit provides testing package hooks and convenience functions for writing tests in an xUnit style.

Package sqlmock is a mock library implementing sql driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow.

@codego-vcr simplifies testing by recording your HTTP interactions and replaying them in future runs in order to provide fast, deterministic and accurate testing of your code.

Ginkgo is a Behaviour-Driven Development testing framework for Go. It builds on top of Go's builtin testing library and is complemented by the Gomega matcher library.

This package provides an implementation of failpoints for Golang.

Package tbltest implements helper functions to help write table driven tests.

Package clock provides an abstraction for system time that enables testing of time-sensitive code.

This package implements a functionality to mock a PostgreSQL server.

Package reqtrace contains a very simple request tracing framework.

This package implements an extension of Table-Driven Testing. Instead of building and iterating over a table in the test code, the input is further separated into files (or inline strings). For certain classes of tests, this can significantly reduce the friction involved in writing and reading these tests.

Package testfs provides a simple fs.FS which is contained in a test (using testing.TB's TempDir) and with a few helper methods.

gomock is a mocking framework for the Go programming language. It integrates well with Go's built-in testing package, but can be used in other contexts too.

Gofuzz is a library for populationg Go objects with random values for the purpose of fuzz testing.

This package implements a few functions that are useful for io testing, such as readers and writers that fail after N consecutive reads/writes.

Package qt implements assertions and other helpers wrapped around the standard library's testing types.

fgprof is a sampling Go profiler providing analyze On-CPU as well as Off-CPU (e.g. I/O) time together.

Go's builtin sampling CPU profiler can only show On-CPU time, but it's better than fgprof at that. Go also includes tracing profilers that can analyze I/O, but they can't be combined with the CPU profiler.

fgprof is designed for analyzing applications with mixed I/O and CPU workloads. This kind of profiling is also known as wall-clock profiling.

gotestspace is used to quickly create a working directory for shell execution using Go, as well as a tool for customizing the execution of the shell. It can help you quickly create an independent workspace for unit testing and improve the efficiency of unit test writing.

Package archive provides helper functions for dealing with archive files.
