php - Is it possible to create a mock outside a test case in PhpUnit?

Question

It may seem silly, hope not, but I want to create a service that will return mock objects for people that uses my project so they can mock all the classes from my project and test their code.

My idea was to offer this kind of service so it can be called inside other project's test cases and obtain the appropriate mock for each test.

Is that possible? Or there are other ways to do that. Btw, I can't use any mocking library because of project's limitations.

Yes, it is possible. Under the hood the getMock method uses the PHPUnit_Framework_MockObject_Generator class. So you can use it directly:

PHPUnit_Framework_MockObject_Generator::getMock($originalClassName, $methods)

But you will lose all the expectation shortcuts like $this->once(). You will have to instantiate the expectations on your own:

$mock->expects(PHPUnit_Framework_TestCase::once())

Look at the PHPUnit source code to see how the mocks are build
