# Contributing to Testify
So you'd like to contribute to Testify? First of all, thank you! Testify is widely used, so each
contribution has a significant impact within the Golang community! Below you'll find everything you
need to know to get up to speed on the project.
## Philosophy
The Testify maintainers generally attempt to follow widely accepted practices within the Golang
community. That being said, the first priority is always to make sure that the package is useful to
the community. A few general guidelines are listed here:
*Keep it simple (whenever practical)* - Try not to expand the API unless the new surface area
provides meaningful benefits. For example, don't add functions because they might be useful to
someone, someday. Add what is useful to specific users, today.
*Ease of use is paramount* - This means good documentation and package organization. It also means
that we should try hard to use meaningful, descriptive function names, avoid breaking the API
unnecessarily, and try not to surprise the user.
*Quality isn't an afterthought* - Testify is a testing library, so it seems reasonable that we
should have a decent test suite. This is doubly important because a bug in Testify doesn't just mean
a bug in our users' code, it means a bug in our users' tests, which means a potentially unnoticed
and hard-to-find bug in our users' code.
## Pull Requests
We welcome pull requests! Please include the following in the description:
* Motivation, why your change is important or helpful
* Example usage (if applicable)
* Whether you intend to add / change behavior or fix a bug
Please be aware that the maintainers may ask for changes. This isn't a commentary on the quality of
your idea or your code. Testify is the result of many contributions from many individuals, so we
need to enforce certain practices and patterns to keep the package easy for others to understand.
Essentially, we recognize that there are often many good ways to do a given thing, but we have to
pick one and stick with it.
See `MAINTAINERS.md` for a list of users who can approve / merge your changes.
## Issues
If you find a bug or think of a useful feature you'd like to see added to Testify, the best thing
you can do is make the necessary changes and open a pull request (see above). If that isn't an
option, or if you'd like to discuss your change before you write the code, open an issue!
Please provide enough context in the issue description that other members of the community can
easily understand what it is that you'd like to see.

Testify - Thou Shalt Write Tests
================================
️ We are working on testify v2 and would love to hear what you'd like to see in it, have your say here: https://cutt.ly/testify
[![Build Status](https://github.com/stretchr/testify/actions/workflows/main.yml/badge.svg?branch=master)](https://github.com/stretchr/testify/actions/workflows/main.yml) [![Go Report Card](https://goreportcard.com/badge/github.com/stretchr/testify)](https://goreportcard.com/report/github.com/stretchr/testify) [![PkgGoDev](https://pkg.go.dev/badge/github.com/stretchr/testify)](https://pkg.go.dev/github.com/stretchr/testify)
Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
Features include:
* [Easy assertions](#assert-package)
* [Mocking](#mock-package)
* [Testing suite interfaces and functions](#suite-package)
Get started:
* Install testify with [one line of code](#installation), or [update it with another](#staying-up-to-date)
* For an introduction to writing test code in Go, see https://go.dev/doc/code#Testing
* Check out the API Documentation https://pkg.go.dev/github.com/stretchr/testify
* A little about [Test-Driven Development (TDD)](https://en.wikipedia.org/wiki/Test-driven_development)
[`assert`](https://pkg.go.dev/github.com/stretchr/testify/assert "API documentation") package
-------------------------------------------------------------------------------------------
The `assert` package provides some helpful methods that allow you to write better test code in Go.
* Prints friendly, easy to read failure descriptions
* Allows for very readable code
* Optionally annotate each assertion with a message
See it in action:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
// assert equality
assert.Equal(t, 123, 123, "they should be equal")
// assert inequality
assert.NotEqual(t, 123, 456, "they should not be equal")
// assert for nil (good for errors)
assert.Nil(t, object)
// assert for not nil (good when you expect something)
if assert.NotNil(t, object) {
// now we know that object isn't nil, we are safe to make
// further assertions without causing any errors
assert.Equal(t, "Something", object.Value)
}
}
```
* Every assert func takes the `testing.T` object as the first argument. This is how it writes the errors out through the normal `go test` capabilities.
* Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
if you assert many times, use the below:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
assert := assert.New(t)
// assert equality
assert.Equal(123, 123, "they should be equal")
// assert inequality
assert.NotEqual(123, 456, "they should not be equal")
// assert for nil (good for errors)
assert.Nil(object)
// assert for not nil (good when you expect something)
if assert.NotNil(object) {
// now we know that object isn't nil, we are safe to make
// further assertions without causing any errors
assert.Equal("Something", object.Value)
}
}
```
[`require`](https://pkg.go.dev/github.com/stretchr/testify/require "API documentation") package
---------------------------------------------------------------------------------------------
The `require` package provides same global functions as the `assert` package, but instead of returning a boolean result they terminate current test.
These functions must be called from the goroutine running the test or benchmark function, not from other goroutines created during the test.
Otherwise race conditions may occur.
See [t.FailNow](https://pkg.go.dev/testing#T.FailNow) for details.
[`mock`](https://pkg.go.dev/github.com/stretchr/testify/mock "API documentation") package
----------------------------------------------------------------------------------------
The `mock` package provides a mechanism for easily writing mock objects that can be used in place of real objects when writing test code.
An example test function that tests a piece of code that relies on an external object `testObj`, can set up expectations (testify) and assert that they indeed happened:
```go
package yours
import (
"testing"
"github.com/stretchr/testify/mock"
)
/*
Test objects
*/
// MyMockedObject is a mocked object that implements an interface
// that describes an object that the code I am testing relies on.
type MyMockedObject struct{
mock.Mock
}
// DoSomething is a method on MyMockedObject that implements some interface
// and just records the activity, and returns what the Mock object tells it to.
//
// In the real object, this method would do something useful, but since this
// is a mocked object - we're just going to stub it out.
//
// NOTE: This method is not being tested here, code that uses this object is.
func (m *MyMockedObject) DoSomething(number int) (bool, error) {
args := m.Called(number)
return args.Bool(0), args.Error(1)
}
/*
Actual test functions
*/
// TestSomething is an example of how to use our test object to
// make assertions about some target code we are testing.
func TestSomething(t *testing.T) {
// create an instance of our test object
testObj := new(MyMockedObject)
// set up expectations
testObj.On("DoSomething", 123).Return(true, nil)
// call the code we are testing
targetFuncThatDoesSomethingWithObj(testObj)
// assert that the expectations were met
testObj.AssertExpectations(t)
}
// TestSomethingWithPlaceholder is a second example of how to use our test object to
// make assertions about some target code we are testing.
// This time using a placeholder. Placeholders might be used when the
// data being passed in is normally dynamically generated and cannot be
// predicted beforehand (eg. containing hashes that are time sensitive)
func TestSomethingWithPlaceholder(t *testing.T) {
// create an instance of our test object
testObj := new(MyMockedObject)
// set up expectations with a placeholder in the argument list
testObj.On("DoSomething", mock.Anything).Return(true, nil)
// call the code we are testing
targetFuncThatDoesSomethingWithObj(testObj)
// assert that the expectations were met
testObj.AssertExpectations(t)
}
// TestSomethingElse2 is a third example that shows how you can use
// the Unset method to cleanup handlers and then add new ones.
func TestSomethingElse2(t *testing.T) {
// create an instance of our test object
testObj := new(MyMockedObject)
// set up expectations with a placeholder in the argument list
mockCall := testObj.On("DoSomething", mock.Anything).Return(true, nil)
// call the code we are testing
targetFuncThatDoesSomethingWithObj(testObj)
// assert that the expectations were met
testObj.AssertExpectations(t)
// remove the handler now so we can add another one that takes precedence
mockCall.Unset()
// return false now instead of true
testObj.On("DoSomething", mock.Anything).Return(false, nil)
testObj.AssertExpectations(t)
}
```
For more information on how to write mock code, check out the [API documentation for the `mock` package](https://pkg.go.dev/github.com/stretchr/testify/mock).
You can use the [mockery tool](https://vektra.github.io/mockery/latest/) to autogenerate the mock code against an interface as well, making using mocks much quicker.
[`suite`](https://pkg.go.dev/github.com/stretchr/testify/suite "API documentation") package
-----------------------------------------------------------------------------------------
The `suite` package provides functionality that you might be used to from more common object-oriented languages. With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal.
An example suite is shown below:
```go
// Basic imports
import (
"testing"
"github.com/stretchr/testify/assert"
"github.com/stretchr/testify/suite"
)
// Define the suite, and absorb the built-in basic suite
// functionality from testify - including a T() method which
// returns the current testing context
type ExampleTestSuite struct {
suite.Suite
VariableThatShouldStartAtFive int
}
// Make sure that VariableThatShouldStartAtFive is set to five
// before each test
func (suite *ExampleTestSuite) SetupTest() {
suite.VariableThatShouldStartAtFive = 5
}
// All methods that begin with "Test" are run as tests within a
// suite.
func (suite *ExampleTestSuite) TestExample() {
assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
}
// In order for 'go test' to run this suite, we need to create
// a normal test function and pass our suite to suite.Run
func TestExampleTestSuite(t *testing.T) {
suite.Run(t, new(ExampleTestSuite))
}
```
For a more complete example, using all of the functionality provided by the suite package, look at our [example testing suite](https://github.com/stretchr/testify/blob/master/suite/suite_test.go)
For more information on writing suites, check out the [API documentation for the `suite` package](https://pkg.go.dev/github.com/stretchr/testify/suite).
`Suite` object has assertion methods:
```go
// Basic imports
import (
"testing"
"github.com/stretchr/testify/suite"
)
// Define the suite, and absorb the built-in basic suite
// functionality from testify - including assertion methods.
type ExampleTestSuite struct {
suite.Suite
VariableThatShouldStartAtFive int
}
// Make sure that VariableThatShouldStartAtFive is set to five
// before each test
func (suite *ExampleTestSuite) SetupTest() {
suite.VariableThatShouldStartAtFive = 5
}
// All methods that begin with "Test" are run as tests within a
// suite.
func (suite *ExampleTestSuite) TestExample() {
suite.Equal(suite.VariableThatShouldStartAtFive, 5)
}
// In order for 'go test' to run this suite, we need to create
// a normal test function and pass our suite to suite.Run
func TestExampleTestSuite(t *testing.T) {
suite.Run(t, new(ExampleTestSuite))
}
```

//
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// )
//
// func TestSomething(t *testing.T) {
//
// var a string = "Hello"
// var b string = "Hello"
//
// assert.Equal(t, a, b, "The two words should be the same.")
//
// }
//
// if you assert many times, use the format below:
//
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// )
//
// func TestSomething(t *testing.T) {
// assert := assert.New(t)
//
// var a string = "Hello"
// var b string = "Hello"

// assert.Equal(a, b, "The two words should be the same.")
// }
//
// # Assertions
//
// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
// All assertion functions take, as the first argument, the `*testing.T` object provided by the
// testing framework. This allows the assertion funcs to write the failings and other details to
// the correct place.

// Every assertion function also takes an optional string message as the final argument,

// Package mock provides a system by which it is possible to mock your objects
// and verify calls are happening as expected.
//
// # Example Usage
//
// The mock package provides an object, Mock, that tracks activity on another object. It is usually
// embedded into a test object as shown below:
//
// type MyTestObject struct {
// // add a Mock object instance
// mock.Mock
//
// // other fields go here as normal
// }
//
// When implementing the methods of an interface, you wire your functions up
// to call the Mock.Called(args...) method, and return the appropriate values.
//
// For example, to mock a method that saves the name and age of a person and returns
// the year of their birth or an error, you might write this:
//
// func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
// args := o.Called(firstname, lastname, age)
// return args.Int(0), args.Error(1)
// }
//
// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
// index position. Given this argument list:
//
// (12, true, "Something")
//
// You could read them out strongly typed like this:
//
// args.Int(0)
// args.Bool(1)
// args.String(2)
//
// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
//
// return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
//
// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
// cases you should check for nil first.

// Package suite contains logic for creating testing suite structs
// and running the methods on those structs as tests. The most useful
// piece of this package is that you can create setup/teardown methods
// on your testing suites, which will run before/after the whole suite
// or individual tests (depending on which interface(s) you
// implement).
//
// A testing suite is usually built by first extending the built-in
// suite functionality from suite.Suite in testify. Alternatively,
// you could reproduce that logic on your own if you wanted (you
// just need to implement the TestingSuite interface from
// suite/interfaces.go).
//
// After that, you can implement any of the interfaces in
// suite/interfaces.go to add setup/teardown functionality to your
// suite, and add any methods that start with "Test" to add tests.
// Methods that do not match any suite interfaces and do not begin
// with "Test" will not be run by testify, and can safely be used as
// helper methods.
//
// Once you've built your testing suite, you need to run the suite
// (using suite.Run from testify) inside any function that matches the
// identity that "go test" is already looking for (i.e.
// func(*testing.T)).
//
// Regular expression to select test suites specified command-line
// argument "-run". Regular expression to select the methods
// of test suites specified command-line argument "-m".
// Suite object has assertion methods.
//
// A crude example:
//
// // Basic imports
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// "github.com/stretchr/testify/suite"
// )
//
// // Define the suite, and absorb the built-in basic suite
// // functionality from testify - including a T() method which
// // returns the current testing context
// type ExampleTestSuite struct {
// suite.Suite
// VariableThatShouldStartAtFive int
// }
//
// // Make sure that VariableThatShouldStartAtFive is set to five
// // before each test
// func (suite *ExampleTestSuite) SetupTest() {
// suite.VariableThatShouldStartAtFive = 5
// }
//
// // All methods that begin with "Test" are run as tests within a
// // suite.
// func (suite *ExampleTestSuite) TestExample() {
