    $client = static::createClient();
    $this->client = $client;
}


    public function testForm()
{

    $crawler = $this->client->request('GET', '/test');
    $form = $crawler->selectButton('.btn btn-lg btn-yellow')->form();

    $form->setValues(
        array(
            'form[search[searchName]]' => 'nom',
            //'form[search]' => 'search'
        )
    );

    $this->client->submit($form);

There are two issues with your current approach: First selectLink() does not work with arbitrary CSS selectors. Also separating class names with spaces does not mean that the desired element has all class names (your selector would filter for a btn-yellow element inside a btn-lg element inside an element having the class .btn ).

If you want to filter for an element with multiple classes you would have to do that like this: $crawler->filter('.btn.btn-lg.btn-yellow')
