How to test exception handler with phpspec

I am stumbling a bit with finding a way to test that my exception handler is being called upon thrown Exception.

This is the idea that I initially working with for the testing:

class ClientSpec extends ObjectBehavior
{
    function it_should_catch_exceptions(Config $config)
    {
        $e = new Exception('test exception');
        $this->catchException($e)->shouldBeCalled();
        throw $e;
    }
}

The Client has a method catchException which will be set as exception handler through set_exception_handler: http://php.net/set_exception_handler.

Running this test gives me this feedback: no beCalled([array:0]) matcher found for null, so I've also tried to do create a spec for Exception and do the following:

class ExceptionSpec extends ObjectBehavior
{
    function it_should_trigger_opbeat_client_when_thrown(Client $client)
    {
        $client->catchException($this)->shouldBeCalled();
        throw $this->getWrappedObject();
    }
}

But running this test returns another error: exception [exc:Exception("")] has been thrown

How can I test that my exception handler is called?

I'm afraid you cannot test an exception handler using phpspec, PHPUnit or other similar testing tool because they wrap the test you write into a try-catch block in order to catch any uncaught exception and report it.

On the other hand, the documentation of set_expection_handler() says:

Sets the default exception handler if an exception is not caught within a try/catch block.

Since phpspec catches all the exceptions your test code throws, the exception handler you install does not have a chance to run :-(

I think all uncaught exceptions end their adventure in ExampleRunner.php at line 96
