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

Package oglematchers provides a set of matchers useful in a testing or mocking framework. These matchers are inspired by and mostly compatible with Google Test for C++ and Google JS Test.

This package provides additions to Go's stdlib testing.

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.

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

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

This package implements value validations for structs and individual fields based on tags. It has the following unique features:

• Cross Field and Cross Struct validations by using validation tags or custom validators

• Slice, Array and Map diving, which allows any or all levels of a multidimensional field to be validated

• Ability to dive into both map keys and values for validation

• Handles type interface by determining it's underlying type prior to validation

• Handles custom field types such as sql driver Valuer

• Alias validation tags, which allows for mapping of several validations to a single tag for easier defining of validations on structs

• Extraction of custom defined Field Name e.g. can specify to extract the JSON name while validating and have it available in the resulting FieldError

• Customizable i18n aware error messages.

• Default validator for the gin web framework

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

This package provides an command line interface (CLI) tool.

This package provides a support of reading and writing of xz compressed streams. It includes also a gxz command for compressing and decompressing data. The package is completely written in Go and doesn't have any dependency on any C code.

Package archive provides helper functions for dealing with archive files.

This package implements a native XZ decompression in Golang.

This package provides a library for encoding and decoding ZIP archive format's "Extra Fields". The intention is to eventually support and provide a low-level API for the majority of PKWARE's and Info-ZIP's extra fields.

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.

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

This package implements parallel gzip compression and decompression in Golang and is fully compatible with compress/gzip from the standard library. This is beneficial for large amounts of data, say more than 1MB at a time, as otherwise the internal gzip library will likely be faster.

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 provides a library for reading RAR archives with Golang.

This package provides a Go implementation of the Snappy compression format.

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

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 provides an additional command line interface tool to compress and decompress LZ4 files.

compress provides various compression algorithms.

Fastzip is an opinionated Zip archiver and extractor with a focus on speed. Features:

• archiving and extraction of files and directories can only occur within a specified directory

• permissions, ownership (uid, gid on linux/unix) and modification times are preserved

• buffers used for copying files are recycled to reduce allocations

• files are archived and extracted concurrently

• by default, github.com/klauspost/compress/flate library is used for compression and decompression

This package is a brotli compressor and decompressor implemented in Go. It was translated from the reference implementation (https://github.com/google/brotli) with the c2go tool at https://github.com/andybalholm/c2go.
