Sorry, but I don't understand the use case.

---------------------------------------------------------------------------

by kosssi at 2013-01-07T10:36:31Z

if you have this code :
    \<img src="..." alt="">

you can find
    $this->assertCount(1, $crawler->filter('img[alt=""]'));

Then, can you change the unit test with the real use case?

by kosssi at 2013-01-07T11:05:50Z

I don't know if it suits you
