Staticcheck is a state of the art linter for the Go programming language. Using static analysis, it finds bugs and performance issues, offers simplifications, and enforces style rules.

This package provides tools for detecting deadlocks at run-time in Go.

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.

Mint (mint.Mint) is wrapper for *testing.T blending testing type to omit repeated t.

Package sloglint implements the sloglint analyzer. The log/slog API allows two different types of arguments: key-value pairs and attributes.

Package gostub is used for stubbing variables in tests, and resetting the original value once the test has been run.

This package offers a method of programmatically retrieving the current goroutine's ID.

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 command line interface (CLI) tool.

Package quicktest provides a collection of Go helpers for writing tests.

Reports unused function parameters and results in Go code.

pgmockproxy is a PostgreSQL proxy that logs the messages back and forth between the PostgreSQL client and server. This can aid in building a mocking script by running commands against a real server to observe the results. It can also be used to debug applications that speak the PostgreSQL wire protocol without needing to use a tool like Wireshark.

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 a quick and easy string diffing functions based on github.com/sergi/go-diff, mainly for diffing strings in tests.

Package fake is the fake data generatror for go (Golang), heavily inspired by forgery and ffaker Ruby gems.

Package spew implements a deep pretty printer for Go data structures to aid in debugging.

A quick overview of the additional features spew provides over the built-in printing facilities for Go data types are as follows:

• Pointers are dereferenced and followed.

• Circular data structures are detected and handled properly.

• Custom Stringer/error interfaces are optionally invoked, including on unexported types.

• Custom types which only implement the Stringer/error interfaces via a pointer receiver are optionally invoked when passing non-pointer variables.

• Byte arrays and slices are dumped like the hexdump -C command which includes offsets, byte values in hex, and ASCII output (only when using Dump style).

This package prints the layout of a struct in Go, which is the byte offset and size of each field, respecting padding. This information is printed in human-readable form by default, or as JSON with the -json flag.

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

Package assert implements the same assertions as the assert package but stops test execution when a test fails.

This package provides JSON equality assertions for Golang.

Rapid is a Go library for property-based testing.

Rapid checks that properties you define hold for a large number of automatically generated test cases. If a failure is found, rapid automatically minimizes the failing test case before presenting it.

Features:

• imperative Go API with type-safe data generation using generics

• data generation biased to explore "small" values and edge cases more thoroughly

• fully automatic minimization of failing test cases

• persistence and automatic re-running of minimized failing test cases

• support for state machine ("stateful" or "model-based") testing

• no dependencies outside the Go standard library

A mini testing helper for Go.

• It has a simple interface (is.OK and is.Equal).

• It plugs into existing Go toolchain (uses testing.T).

• It's obvious for newcomers.

• It also gives you is.Panic and is.PanicWith helpers - because testing panics is ugly.

Package is provides a lightweight extension to the standard library's testing capabilities.

The gls package provides a way to store a retrieve values per-goroutine.

Package httpmock provides tools for mocking HTTP responses. It implements exact URL and regexp matches.
