Mocktation

PHP Mocking using annotations

Mocktation lets you define return values of class methods when mocking, instead of having to define each return value in your tests.

By annotating using @mockReturn "test", the method will return "test" by default when calling the method after creating a mock using $this->createMock(CLASSNAME) in your tests.

This speeds up development since you can define default mock return values when writing the method, instead of retroactively deciding on mock values.

1. Install Mocktation

   composer require-dev prodikl/mocktation

2. Extend Mocktation/Testcase instead of PHPUnit TestCases

   use Mocktation\TestCase;
   
   class ExampleTest extends TestCase {
       public function testGetNum(){
           /** @var Example|MockObject $mock */
           $mock = $this->createMock(Example::class);
           $this->assertEquals(5, $mock->getNum(234));
       }
   } 

3. Use annotations to describe mocking in your methods

   class Example {
       /**
        * Accepts an int $num and returns it
        *
        * @param $num      int     The num to return
        * @return int      The example num
        *
        * @mockReturn      5
        */
       public function getNum($num){
           return $num;
       }
   }

Here's a list of Mocktation annotations

• @mockReturn [returnValue] - Returns the [returnValue] when called
• @mockReturnArgument [argumentNumber] - Returns the [argumentNumber] when called. [argumentNumber] starts from 0.
