PHPUnit Testing Exceptions for Laravel Resource Controllers

Question

Is it possible to test Exceptions with Laravel resource controllers? Every time I try to do the following:

/**
 * @expectedException Exception
 * @expectedExceptionMessage Just testing this out
 */
public function testMyPost() {
    $response = $this->call('POST', '/api/myapi/', array('testing' => 1));
}

I get:

Failed asserting that exception of type "Exception" is thrown.

I've tried this with \Exception and Exception.

In my resource controller I have:

public function store() {
    throw new \Exception('Just for testing!');
}

Does anyone has any idea of I can test Exceptions? I've also tried using:

    $this->setExpectedException('InvalidArgumentException');

what if you specify it as @expectedException \\Exception ? — zerkms

Same :( Failed asserting that exception of type "\\Exception" is thrown. — mayrop

What if you wrap your call with try-catch and get the exact type of exception with get_class($e)? Presumably it's $this->call() what throws an exception, and your original exception is handled by something else. — zerkms

Nothing is thrown.. even if I call $response = $this->action('POST', 'APIController@store');, nothing seems to be thrown. — mayrop

what if you send POST with curl and see what is actually returned to you? — zerkms

The problem is as hannesvdvreken states; the exception is caught. An easy work-around is to tell Laravels errort/exception handler, that when we are testing, we just want our exceptions thrown.

That could look something like this:

    // If we are testing, just throw the exception.
    if (App::environment() == 'testing') {
        throw $e;
    }

For Laravel 5, this should go in the render method in app/Exceptions/Handler.php

For Laravel 4, this should go in app/start/global.php within:

App::error(function(Exception $exception, $code)...

Don't focus on the notation of @expectedException. The problem is the Exception is catched somewhere. Maybe with the default App::error(function(Exception) {... inside the app/start/global.php file.

Or maybe you did a try catch somewhere. Try making a custom Exception that does not get catched by a generic exception catcher that catches everything that's inherited from Exception.

I'll try the custom Exception and let you know. But, at the end of the day I'll will want to catch the Exceptions so my application doesn't break, but if I do that, then the Unit testing will not work :(
