Stub out the global craft() object for PHPUnit tests

Question

As best I can tell, the 'mockBuilder' function is exactly what I want, and based on other examples, should work.

Am I missing something? How can I stub out the global craft() object?

under test:

<?php

namespace Craft;


class JobsVariable
{

     // Grab all Jobss
     public function jobs()
      {
            return craft();
      }
 }

test file:

    <?php

    namespace Craft;

    require_once 'www/craftcms/plugins/jobs/variables/JobsVariable.php';


    class JobsVariableTest extends \PHPUnit_Framework_TestCase
    {



        public function testJobs()
        {


            $craft = $this->getMockBuilder('\\Craft')
                ->disableOriginalConstructor()
                ->setMethods(array('craft'))
                ->getMock();


            $craft->method('craft')->willReturn('xxx');


            $jobs = new \Craft\JobsVariable();
            $this->assertEquals('xxx', $jobs->jobs());

        }
    }

output:

PHP Fatal error:  Call to undefined function Craft\craft()

Answer 1

Whew...this seems to do the trick! Hopefully this is an appropriate way to handle things.

I created a new Craft class file in the 'tests' dir. There I can stub out any \Craft\craft() methods the class under test depends on.

stub class \tests\Craft

<?php

class Craft {

    public function __construct()
    {
    }

    public function jobs()
    {
        return 'xxx';
    }
    public function getJobs()
    {
        return 'xxx';
    }

    public function craft()
    {
        return $this;
    }
}

in the test class

<?php

namespace Craft;

require_once '/www/craftcms/plugins/jobs/variables/JobsVariable.php';
require_once '/www/craftcms/tests/Craft.php';


class JobsVariableTest extends \PHPUnit_Framework_TestCase
{

    public function testJobs()
    {
        $jobs = new \Craft\JobsVariable();
        $this->assertEquals('xxx', $jobs->jobs());

    }
}
function craft()
{
    return new \Craft;
}

allows me to test this function...

public function jobs()
{
    return craft()->jobs();
}

Answer 2

...and because the actual test method to get mocked looks like this: craft()->jobs->getJobs()

I can mock this up by adding a class to my stubbed out \test\Craft class;

<?php

class Craft {

    public $jobs;

    public function __construct()
    {
        $this->jobs = new Jobs;
    }
}


class Jobs{

    public function __construct(){
        var_dump('new jobs');
    }


    public function getJobs(){
        return 'xxx';
    }
}

Now I can return dummy test data ('xxx'), instead of letting the code make network requests for real data.
