assert is a testing library that provides high-level assertions API based on Go testing library procedures.

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.

This package implements UDP test helpers. It lets assert that certain strings must or must not be sent to a given local UDP listener.

Package ogletest provides a framework for writing expressive unit tests. It integrates with the builtin testing package, so it works with the gotest command. Unlike the testing package which offers only basic capabilities for signalling failures, it offers ways to express expectations and get nice failure messages automatically.

This package takes the results from multiple go test -coverprofile runs and merges them into one profile.

This package provides a test library for the Go language.

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

Reports unused function parameters and results in Go code.

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

This package is a straight copy of the excellent Ginkgo library, stripped to the bare core to be free of third-party dependencies.

This package provides a test corpus of C code.

The deep package provides the deep.Equal function which is like reflect.DeepEqual but returns a list of differences. This is helpful when comparing complex types like structures and maps.

Correct is a collection of assertion libraries for Golang, intended to be used together. It tries not to strictly enforce that, though - most of correct should be customizeable either by changing some options or by using only some sub-packages of correct.

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

compress provides various compression algorithms.

lz4 provides a streaming interface to LZ4 data streams as well as low level compress and uncompress functions for LZ4 data blocks. The implementation is based on the reference C one.

This package implements a functionality for pristinely disassembling a tar archive, and stashing needed raw bytes and offsets to reassemble a validating original archive.

Package archive provides helper functions for dealing with archive files.

This package provides an enhanced version of the compress/lzw library included in the stdlib, and supports GIF, TIFF and PDF.

This package provides a Go wrapper to zstd C library.

This package implements reader/writer library eStargz - a lazily-pullable image format.

This package provides a library for reading RAR archives with Golang.

Package compress is a collection of compression libraries implementing Golang modules:

brotli

Implements the Brotli format, described in RFC 7932.

bzip2

Implements the BZip2 compressed data format.

flate

Implements the DEFLATE format, described in RFC 1951.

xflate

Implements the XFLATE format, an random-access extension to DEFLATE.

Package archiver facilitates convenient, cross-platform, high-level archival and compression operations for a variety of formats and compression algorithms.

Features:

• stream-oriented APIs

• automatically identify archive and compression formats

• traverse directories, archive files, and any other file uniformly as io/fs file systems

• compress and decompress files

• create and extract archive files

• walk or traverse into archive files

• insert (append) into .tar and .zip archives

• read from password-protected 7-Zip files

• numerous archive and compression formats supported

• extensible (add more formats just by registering them)

• cross-platform, static binary

• pure Golang (no cgo)

• multithreaded Gzip

• adjust compression levels

• automatically add compressed files to zip archives without re-compressing

• open password-protected rar archives
