Base Class for creating reusable PHPUnit Mock Objects

• Allows for simple sharing of mocks (build them once)
• Allows simple array config for any mock return
• Mocks can follow class structure of your project

    - src
    -- MyPackage
    --- MyClass
    - mocks
    -- MyPackage
    --- MyClass

Example

Test Target

namespace MyPackage;

class MyClass 
{
    public function myMethod() 
    {
        return 'someValue'
    }
}

Simple Mock Setup

Use this when your config is one-to-one with the mocks methods and results

namespace MyPackage;

class MyClassMock extends \PhpUnitMock\Mock 
{
    /**
     * NameSpace and Name of the class to mock
     *
     * @var null
     */
    protected $className = '\MyPackage\MyClass';
    
    /**
     * Build the default mock configuration
     *
     * @return array
     */
    public function buildDefaultConfig()
    {
        return [
            'myMethod' => 'SOME_TEST_VALUE'
        ];
    }

    /**
     * @override to show proper type hinting in IDE
     * Build PHPUnit Mock in this method
     *
     * @return \MyPackage\MyClass
     */
    public function buildMock() 
    {
            return parent::buildMock();
    }
}

Custom Mock Setup

Use this when you require special cases for you mock results

namespace MyPackage;

class MyClassMock extends \PhpUnitMock\Mock 
{
    /**
     * Build the default mock configuration
     *
     * @return array
     */
    public function buildDefaultConfig()
    {
        return [
            'myMethod' => 'SOME_TEST_VALUE'
        ];
    }

    /**
     * @override to show proper type hinting in IDE
     * Build PHPUnit Mock in this method
     *
     * @return \MyPackage\MyClass
     */
    public function buildMock() 
    {
        /** @var \MyPackage\MyClass $mock */
        $mock = $this->testCase->getMockBuilder('\MyPackage\MyClass')
            ->disableOriginalConstructor()
            ->getMock();

        $mock->method('myMethod')
            ->will($this->returnValue($this->config['myMethod']));
            
        // Custom mock building here
            
        return $mock;
    }
}

Simple Usage

namespace MyPackage;

class MyClassTest extends \PHPUnit_Framework_TestCase 
{
    public function testMyMethod() 
    {
        // Default Mock with default config 
        $mock = MyClassMock::build($this);
        
        // Returns 'SOME_TEST_VALUE' from default config
        $mock->myMethod();
        
        // Over-ride Mock return value
        $mock = MyClassMock::build(
            $this,
            // Add local config, this will be merged with the default config
            [
                'myMethod' => 'DIFFERENT_TEST_VALUE'
            ];
        );
        
        // Returns 'DIFFERENT_TEST_VALUE' from local config
        $mock->myMethod();
    }
}

Usage with Type Hints in IDE

namespace MyPackage;

class MyClassTest extends \PHPUnit_Framework_TestCase 
{
    public function testMyMethod() 
    {
        // Default Mock with default config 
        $mock = MyClassMock::get($this)->buildMock();
        
        // Returns 'SOME_TEST_VALUE' from default config
        $mock->myMethod();
        
        // Over-ride Mock return value
        $mock = MyClassMock::get(
            $this,
            // Add local config, this will be merged with the default config
            [
                'myMethod' => 'DIFFERENT_TEST_VALUE'
            ];
        )->buildMock();
        
        // Returns 'DIFFERENT_TEST_VALUE' from local config
        $mock->myMethod();
    }
}
