**The v2 our tests wanted**

A set of `go` packages that provide tools for testifying (verifying) that your code behaves as you intended.

This is the go-openapi fork of the great [testify](https://github.com/stretchr/testify) package.

> [!NOTE]
> This is the home of `github.com/go-openapi/testify/v2`, an active, opinionated fork of `github.com/stretchr/testify`.

## Why choose `go-openapi/testify/v2`

* 95% compatible with `stretchr/testify` — if you already use it, our migration tool automates the switch
* Actively maintained: regular fixes and evolutions, many PRs proposed upstream are already in
* Zero external dependencies — you import what you need, with opt-in modules for extras (e.g. YAML, colorized output)
* Modernized codebase targeting go1.25+
* Go routine leak detection built in: zero-setup, no false positives, works with parallel tests (unlike `go.uber.org/goleak`)
* File descriptor leak detection (linux-only)
* Type-safe assertions with generics (see [a basic example][example-with-generics-url]) — migration to generics can be automated too. [Read the full story][doc-generics]
* Safe async assertions, extended JSON & YAML assertions
* Coming in `v2.5.0`: non-flaky async assertions using `synctest`, and internal tools exposed as standalone modules (spew, unified diff, goleak)
* We take documentation seriously: [searchable doc site][doc-url] with testable examples and a complete tutorial, plus detailed [godoc][godoc-url] for every assertion

### This fork isn't for everyone

* You need the `mock` package — we removed it and won't bring it back. For suites, we're [open to discussion][suite-discussion] about a redesigned approach
* Your project must support Go versions older than 1.25
* You rely on `testifylint` or other tooling that expects the `stretchr/testify` import path
* You need 100% API compatibility — we're at 95%, and the remaining 5% are intentional removals

## Announcements

* **2026-06-22** : preparing v2.6.0 (ETA within 2-3 days)
  - go1.26 optional support
  - `ErrorWithType[E error]` available with go1.26
  - a few minor fixes (reflection-based assertion robustness) thanks to your awesome feedback.

* **2026-06-22** : [ROADMAP][doc-roadmap] to v2.7.0 (ETA Sept. 2026)
  - minor version releases will slow down from monthly to quarterly. Next planned for September
  - go1.27 optional support, with forward methods supporting generics.

## Status

Design and exploration phase completed. The published API is now stable:
moving forward, API changes will remain backward-compatible with v2.4.0.

Feedback, contributions and proposals are welcome.

## Getting started

Import this library in your project like so.

```cmd
go get github.com/go-openapi/testify/v2
```

... and start writing tests. Look at our [examples][doc-examples].

## Basic usage

`testify` simplifies your test assertions like so.

```go
import (
        "testing"
    )
    ...

    const expected = "expected result"

	result := printImports(input)
	if result != expected {
		t.Errorf(
            "Expected: %s. Got: %s", expected, result,
        )

        return
	}
```

Becomes:

```go
import (
        "testing"
        "github.com/go-openapi/testify/v2/require"
    )
    ...

    const expected = "expected result"

	require.Equalf(t,
        expected, printImports(input), "Expected: %s. Got: %s",
        expected, result,
    )
```

## Usage at go-openapi and go-swagger

This fork now fully replaces the original project for all go-openapi projects,
thus reducing their dependencies footprint.

Go-swagger has also adopted it. Now the work is to generalize the use of generics (leveraging our migration tool).

Features might be added to support our main use cases there.

## Cutting a new release

Maintainers can cut a new release by either:

* running [this workflow][ci-release-workflow] (recommended)
* or :
  1. preparing go.mod files with the next tag, merge
  2. pushing a semver tag
  * signed tags are preferred
  * The tag message is prepended to release notes
