@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.

pprof is a tool for visualization and analysis of profiling data.

It reads a collection of profiling samples in profile.proto format and generates reports to visualize and help analyze the data. It can generate both text and graphical reports (through the use of the dot visualization package). This package provides an command line interface (CLI) tool.

This package takes go-structlayout-like JSON and prints an ASCII fraphic representing the memory layout.

wish is a test assertion library for Golang, designed to gracefully enhance standard library testing package and behaviors of the go test command.

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

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

Gomega is the preferred matcher/assertion library for the Ginkgo test framework.

This package provides a contract to share variables between test helpers in Golang.

clock is a small library for mocking time in Go. It provides an interface around the standard library's time package so that the application can use the realtime clock while tests can use the mock clock.

Package ddmin implements the delta-minimization test minimization algorithm.

Clock is a small library for mocking time in Go. It provides an interface around the standard library's time package so that the application can use the realtime clock while tests can use the mock clock. This is a maintained fork of benbjohnson's clock package.

pprof is a tool for visualization and analysis of profiling data.

It reads a collection of profiling samples in profile.proto format and generates reports to visualize and help analyze the data. It can generate both text and graphical reports (through the use of the dot visualization package).

Go package to verify that there are no unexpected goroutines running at the end of a test.

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

Package testza is a full-featured testing framework for Go. It integrates with the default test runner, so you can use it with the standard go test tool. Testza contains easy to use methods, like assertions, output capturing, mocking, and much more.

Reports unused function parameters and results in Go code.

Go-fuzz is a coverage-guided fuzzing solution for testing of Go packages. Fuzzing is mainly applicable to packages that parse complex inputs (both text and binary), and is especially useful for hardening of systems that parse inputs from potentially malicious users (e.g. anything accepted over a network).

This package provides basic assertions along with building blocks for custom assertions to be used alongside native Go testing.

This package provides basic assertions along with building blocks for custom assertions to be used alongside native Go testing.

This package provides scripts and workflows to automate common routines for Golang projects via modular Makefiles and GitHub Actions.

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

This is a linter for Go source code. Unlike gofmt, it doesn't reformat the source code, it only prints out style mistakes.

This package is a simple tracing application that logs messages depending on environment variables. It is very much inspired by git's GIT_TRACE mechanism.

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.
