Testify: A toolkit with Common Assertions and Mocks

Testify - Thou Shalt Write Tests

Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.

Features include:

Easy assertions
Mocking
Testing suite interfaces and functions

Get started:

Install testify with one line of code, or update it with another
For an introduction to writing test code in Go, see http://golang.org/doc/code.html#Testing
Check out the API Documentation http://godoc.org/github.com/stretchr/testify

A little about Test-Driven Development (TDD)

`assert` 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:

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:

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` package

The 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` 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 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)


}

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` 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:

// 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))
}

Installation

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!")

}

Staying up to date

To update Testify to the latest version, use go get -u github.com/stretchr/testify.

Supported go versions

We currently support the most recent major Go versions from 1.13 onward.

Contributing

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.

What is Assertion in Java?

The assertion in Java is used to ensure the correctness of any program’s assumptions as the assertion is assumed to be true when it is executed. The Java Virtual Machine throws an error named AssertionError if the assertion is false. The assertion in Java has found its application mainly for testing purposes. Boolean expressions are used along with assertion statements. An assertion is a statement, and the ‘asset’ keyword is used to carry out an assertion in Java.

Java assertion is an inbuilt statement that ensures the correctness of any assumptions which have been done in the program. When an assertion is executed, it is assumed to be true. If the assertion is false, the JVM will throw an Assertion error. Assertions in Java can be done with the help of the assert keyword.

Suppose there is a condition that you, as a programmer or a developer, while testing your code, want to make sure exists, such as making sure that a particular method shall return only negative values; Java has a (relatively) new feature made available just for that.

The feature is called assertion, and wherein one can assert the existence of a particular condition. It is done with the help of the keyword assert. Assertions are generally used for testing and scarcely used in the release code. Release code is usually run with assertions disabled.

#Why to use Assertions

We can make sure that an unreachable looking code is unreachable.
We can make sure that assumptions written in the comments are right.

         if ((x & 1) == 1)  
         {  }
         else // x must be even 
         { assert (x % 2 == 0); }

We can make sure the default switch case is not reached.
We can check the object’s state.
At the beginning of the method
After the method invocation.

Deep Dive Into WordPress Toolkit 4.7 Release

WordPress Tookit 4.7 is the third major WordPress Toolkit update in 2020. It’s also the first update developed and released by a team working completely remotely due to the current lock down. We’re happy to announce that we were still able to deliver as planned. Read on to learn what was added in this release.

What’s WordPress Toolkit?

Update of Paid Plugins & Themes

Most WordPress agencies and web developers are using paid plugins and themes in their projects. Same goes for WordPress admins who’re at least semi-serious about their site. The main problem with such plugins and themes was that they’re not hosted on wordpress.org. Thus, WordPress Toolkit couldn’t detect their updates and install them. This deficiency led to a miserable user experience where you could update a bunch of plugins and themes via WordPress Toolkit. But for the rest, you had to go through WordPress itself. The Smart Updates feature also couldn’t update such plugins and themes, hence limiting its usefulness.

I’m not exaggerating when I say that this was the main known showstopper on the critical user path in WordPress Toolkit. This is why I’m very happy to announce that we have removed this showstopper in WordPress Toolkit 4.7. If you can see and install the plugin or theme update in WordPress itself, you can do the same in WordPress Toolkit now. Let’s take a closer look.

Here’s how these updates are displayed in WordPress itself:

WordPress Toolkit displays these updates in the same way it displays updates for plugins and themes from wordpress.org:
