Undefined variable in view when testing Laravel controller

Question

I'm trying to test some of the actions on my controller in Laravel 4 with PHPUnit.

public function testAboutPage()
{
    $this->client->request('GET', 'about');

    $this->assertResponseOk();
}

Also, I bind a variable to my views in the App::before() filter.

App::before(function($request)
{
    View::share('usersCount', User::remember(60)->count());
}

Here is my controller:

class PagesController extends BaseController
{
    public function about()
    {
        return View::make('pages.about')->withTitle("About");
    }
}

However, my tests fail before the variable is not defined in testing. Here is the failing output from PHPUnit.

12) PagesControllerTest::testAboutPage
ErrorException: Undefined variable: usersCount (View: app/views/layouts/application.blade.php) (View: app/views/layouts/application.blade.php)

What can I do to resolve this issue? The variable is fine when viewing in a browser or in production.

Added my controller code. As you can see, it's pretty simple. — Dwight

Your error is in the testUnsubscribedPage method, but you only posted the code for the testAboutPage method. — Joseph Silber

Apologies, this issue affects all my tests on the PagesController. I switched my example from testUnsubscribedPage to testAboutPage as the controller action for it is dead simple. — Dwight

From the docs, it turns out that filters are disabled. I thought this just meant filters defined in the routes file, but it impacts app before/after filters also.

Note: Route filters are disabled when in the testing environment. To enable them, add Route::enableFilters() to your test.

I've added this to my tests to make them go green.

public function setUp()
{
    parent::setUp();

    Route::enableFilters();
}
