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.

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

This package provides ciinfo, a tool to get details about the current Continuous Integration environment, including checking if running in a CI system, which CI system, build id, and more.

This is a reimplementation of ci-info in Go.

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.

Assertion library that:

• makes spotting differences in equality much easier

• uses repr and diffmatchpatch to display structural differences in colour

• aborts tests on first assertion failure

go-snaps is a Go implementation of Jest snapshot testing.

@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.

go-testmark is a library to parse, patch data and test fixtures from Markdown files, using the testmark format, which itself is a subset of Markdown format.

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

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

Package assert provides obj set of assertion functions. Every assertion function returns obj boolean. This package does not integrate into the testing package automatically and requires to check the returning boolean value and call t.Fatal() if the assertion fails.

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

Package stub provides helper functions to replace global variables for testing, and restore them afterwards.

This package provides a test library for the Go language.

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).

Package sqlmock is a mock library implementing sql driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection. It helps to maintain correct TDD workflow.

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

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

In Norse mythology, Hel cares for the souls of people who didn't die in battle. This little tool cares for mock implementations of interface types.

This package provides a simple little tool that produces readable diff of 2 JSON-able and convertible to map[string]interface objects. Useful for diagnostics or debugging

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.

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

This package inplements a functionality to collect all .coverprofile files rooted in the project and concatenante them into a single file ready for https://coveralls.io/.
