PhpSpec - PHP-Mock Extension

Adds the PHP Mock function mocking library as a phpspec Collaborator

This phpspec extension allows you to mock non-deterministic PHP core functions (time(), rand(), etc.), or mock functions from other libraries or frameworks that have side effects from dependencies like a database, filesystem or HTTP request.

By using the specially named parameter $functions in any example method, phpspec-php-mock will turn that parameter into a special FunctionCollaborator that wraps the php-mock-prophecy library's PHPProphet. This allows you to mock return values for any function as you normally would for an ObjectProphecy.

Installation

Add this to your composer.json:

    {
        "require-dev": {
            "cyruscollier/phpspec-php-mock": "dev-master"
        }
    }
    

Then add this to your phpspec.yml:

    extensions:
      PhpSpec\PhpMock\Extension\PhpMockExtension: ~

Example

A PHP class that uses a non-deterministic function:

    class Time
    {
        function getCurrentTime()
        {
            return time();
        }
    }

The spec for that class that mocks the time() function:

    use PhpSpec\ObjectBehavior;
    
    class TimeSpec extends ObjectBehavior
    {
        function it_is_initializable()
        {
            $this->shouldHaveType('Time');
        }
    
        function it_gets_the_current_time($functions)
        {
            $functions->time()->willReturn(123);
            $this->getCurrentTime()->shouldReturn(123);
        }
    }

Examples that test Exceptions require an extra line to reveal the function prophecy manually, since the Throw Matcher executes the Subject method differently than the other matchers :

    use PhpSpec\ObjectBehavior;
    
    class TimeSpec extends ObjectBehavior
    {
        function it_is_initializable()
        {
            $this->shouldHaveType('Time');
        }
    
        function it_gets_the_current_time($functions)
        {
            $functions->time()->willReturn(123);
            $functions->reveal();
            $this->shouldThrow('\Exception')->during('getCurrentTime', [123]);
        }
    }
