Handling Laravel HttpException in Unit Testing

One of my test functions for unit testing in Laravel keeps erroring out. I'm trying to assert that requesting a specific page without certain conditions being met triggers a 403 FORBIDDEN error. My test case function is this: ``` public function testNoAjaxCall() { $this->call('POST', 'xyz', array()); $this->assertResponseStatus(403); } ``` In the controller action this is routed to, I have this: ``` if(!Input::has('ajax') || Input::get('ajax') != 1) { // Drop all 'non-ajax' requests. App::abort(403, 'Normal POST requests to this page are forbidden. Please explicitly tell me you\'re using AJAX by passing ajax = 1.'); } ``` Running phpunit returns with the following: 1) RaceTest::testNoAjaxCall Symfony\Component\HttpKernel\Exception\HttpException: Normal POST requests to this page are forbidden. Please explicitly tell me you're using AJAX by passing ajax = 1. [path\to\laravel]\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:875 [redacted stack trace] [path\to\laravel]\vendor\symfony\http-kernel\Symfony\Component\HttpKernel\Client.php:81 [path\to\laravel]\vendor\symfony\browser-kit\Symfony\Component\BrowserKit\Client.php:325 [path\to\laravel]\vendor\laravel\framework\src\Illuminate\Foundation\Testing\TestCase.php:74 [path\to\laravel]\app\tests[testFileName].php:176 FAILURES! Tests: 6, Assertions: 17, Errors: 1. Of course the stack trace points back to `$this->call(..);` and `App::abort(..)` I have a HttpException error handler in my `app/start/global.php` file, which works when triggering it outside of unit testing (e.g. making a `POST` request directly to the tested URL), but unit testing doesn't seem to correctly catch the exception or even reach the assert call. What am I missing?
