ℹ️ 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
Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.
Features include:
Get started:
assert
packageThe assert
package provides some helpful methods that allow you to write better test code in Go.
See it in action:
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)
}
}
testing.T
object as the first argument. This is how it writes the errors out through the normal go test
capabilities.if you assert many times, use the below:
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
packageThe require
package provides same global functions as the assert
package, but instead of returning a boolean result they terminate current test.
See t.FailNow for details.
mock
packageThe 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 setup expectations (testify) and assert that they indeed happened:
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)
// setup 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)
// setup 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)
// setup 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.
You can use the mockery tool to autogenerate the mock code against an interface as well, making using mocks much quicker.
suite
packageThe 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:
// 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
For more information on writing suites, check out the API documentation for the suite
package.
Suite
object has assertion methods:
// 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))
}
To install Testify, use go get
:
go get github.com/stretchr/testify
This will then make the following packages available to you:
github.com/stretchr/testify/assert
github.com/stretchr/testify/require
github.com/stretchr/testify/mock
github.com/stretchr/testify/suite
github.com/stretchr/testify/http (deprecated)
Import the testify/assert
package into your code using this template:
package yours
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestSomething(t *testing.T) {
assert.True(t, true, "True is true!")
}
To update Testify to the latest version, use go get -u github.com/stretchr/testify
.
We currently support the most recent major Go versions from 1.19 onward.
Please feel free to submit issues, fork the repository and send pull requests!
When submitting an issue, we ask that you please include a complete test function that demonstrates the issue. Extra credit for those using Testify to write the test code that demonstrates it.
Code generation is used. Look for CODE GENERATED AUTOMATICALLY
at the top of some files. Run go generate ./...
to update generated files.
We also chat on the Gophers Slack group in the #testify
and #testify-dev
channels.
