Saved mocks

[elliotchance]

A saved mock allows easy and verifiable mocks between integration (or expensive logic) and unit (cheap logic) tests:

public function test1()
{
    $calc = $this->niceMock('Calculator')
                 ->saveAs('calc')
                 ->done();
    $this->assert($calc->add(3, 5), equals, 8);
}

public function test2()
{
    $calc = $this->savedMock('calc');

    // add(3, 5) was prerecorded as returning 8
    $this->assert($calc->add(3, 5), equals, 8);

    // add(3, 7) was not recorded so it has to go back to the original object to calculate it
    $this->assert($calc->add(3, 7), equals, 10);
}

When recording a mock it assumes that;

• All methods are deterministic, that is if I call a method with the same set of arguments I would get the same result.
• Mocks are saved to be available in subsequent run without needing to regenerate the mock.
• If you call a method with arguments that have not been recorded it falls back to the actions defined on the original mock.
