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 cienv implements some helper functions to use during tests. Many times certain facilities are not available, or tests must run differently.

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 provides JSON equality assertions for Golang.

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.

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

Gofuzz is a library for populationg Go objects with random values for the purpose of fuzz testing.

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

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/.

Package is provides a lightweight extension to the standard library's testing capabilities.

Package oglemock provides a mocking framework for unit tests.

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

GoConvey is a testing tool for Go. It integrates with go test, can show test coverage and has a web user interface that will refresh automatically.

Package testdeep allows flexible deep comparison, it is an adaptation of Perl's Test::Deep perl.

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

This package provide many tools for testifying that your code will behave as you intend.

Features include:

• Easy assertions

• Mocking

• HTTP response trapping

• Testing suite interfaces and functions.

Reports unused function parameters and results in Go code.

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

@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.

This package implements a tool to compile native Golang fuzzers to libFuzzer fuzzers.

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

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.
