I have troubles executing a behat/mink test routine in the browser. I have tried sahi and selenium divers, the result is the same:
I run the test, sahi opens the login modal-popup, but does not fill in username and password. Clicking "submit" does work again, but due to the missing username and password the user is not logged in ("wrong username/password" message is shown).
Now the questions:
- Does anyone have an idea why this might happen and what I can do to get the issue fixed
 - Can someone tell me how to slow down execution in the browser (its very hard to follow)
 - Any more ideas on how to debug issues which occur during execution of the test scripts?
 
my feature step for loging in:
    /**
     * @Given /^I am logged in as "([^"]*)"$/
     */
    public function iAmLoggedInAs($username)
    {
        $user = $this->getUserFromUsername($username);
        $this->clickLink('Login');
        $this->fillField('_username',$user->getEmail());
        $this->fillField('_password','12341234');
        $this->pressButton('_submit');
        $this->loggedInUser = $user;
    }
html of the page:
                        
Fields parameters should be either field labels (actual text, not id) or field names.
so solution to your problem is to either use:
