This package provides additions to Go's stdlib testing.

This library enables complex data structure testing, specifically:

• realtime transformation or casting of incompatible data types with directives system

• consistent way of testing of unordered structures

• contains, Range, RegExp support on any data structure deeph level

• switch case directive to provide expected value alternatives based on actual switch/case input match

• macro system enabling complex predicate and expression evaluation, and customization

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

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

This package implements a linter that checks for required fields during struct initialization.

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 tools for detecting deadlocks at run-time in Go.

This package implement a functionality for validating tags according to rules you define and fixing them according to the defined rules.

This package provides a mocking framework which integrates well with built-in testing package, but can be used in other contexts too.

This package is an alternative fork of github.com/icrowley/fake used in go-github-com-jackc-pgx.

This package provides a toolkit for parsing Go language panic stack traces. It simplifies the traces to make salient information more visible and aid debugging.

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.

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 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.

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.

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 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

• extract only specific files from archives

• 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

Supported compression formats:

• brotli (.br)

• bzip2 (.bz2)

• flate (.zip)

• gzip (.gz)

• lz4 (.lz4)

• lzip (.lz)

• snappy (.sz)

• xz (.xz)

• zlib (.zz)

• zstandard (.zst)

Supported archive formats:

• .zip

• .tar (including any compressed variants like .tar.gz)

• .rar (read-only)

• .7z (read-only)

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.

This package implements a seekable version of gzip-format compressed files, compliant with RFC 1952. This implementation allows seeking in the compressed file. In normal gzip files that can only be achieved by decompressing from the start and discarding all data until the selected offset. This gzip implementation works around this by creating a special metadata file that maps uncompressed blocks to compressed blocks allowing it to only read the compressed blocks required.

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

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

Package archive provides helper functions for dealing with archive files.

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