expectException($e) passing class fix

[stampycode]

(example extends PHPUnit_Framework_TestCase)

This works fine:

public function testThrow()
{
    $expected = new \Exception("FOO");
    $this->expectException(get_class($expected));
    throw $expected;
}

This doesn't:

public function testThrow()
{
    $expected = new \Exception("FOO");
    $this->expectException($expected);
    throw $expected;
}

The method signature/PHPDoc for expectException($e) is to accept "mixed" parameter, and doesn't mind when you submit an Exception object - but it won't catch that exception object when it is thrown, even if it's that exact object that is thrown.

I'd suggest either passing instances of Exception generates an InvalidArgumentException, or instances of Exception passed in are just used to call get_class on to stringify them, or the actual instance of that exception is then expected (which I think would be less useful generally).

Either way, accepting the exception object then basically ignoring it isn't ideal...
