How to handle confirm popup with phantomjs + behat + mink

Question

In my tests I use this step to confirm a javascript confirm popup:

/**
 * @when /^(?:|I )confirm the popup$/
 */
public function confirmPopup()
{
    $this->getSession()->getDriver()->getWebDriverSession()->accept_alert();
}

This step work fine with selenium2 and chrome/firefox, but doesn't work with phantomjs.

How can I handle a confirm popup with phantomjs ?

for informations:

symfony: 2.0.23
behat: 2.4.6
mink: 1.5.0
Symfony2Extension: 1.0.2
MinkExtension: 1.1.4
MinkBrowserKitDriver: 1.1.0
MinkSelenium2Driver: 1.1.0
phamtomjs 1.9.1

behat.yml

default:
    extensions:
        Behat\Symfony2Extension\Extension:
            mink_driver: true
        Behat\MinkExtension\Extension:
            base_url: "http://localhost:8000/app_test.php"
            default_session: selenium2
            selenium2:
                wd_host: "http://localhost:9876/wd/hub"

Thanks!

Are you using the native javascript "alert" or a cooked up one? — Ken Hannel, Aug 07 '13 at 16:56
Did you manage to figure this out Benjamin? I've come across the same issue... — Matt, Oct 07 '13 at 18:38
How do you run your tests that include an alert at the mo then, via Selenium? — Matt, Oct 07 '13 at 21:00
phantomjs --webdriver=9876 > /dev/null 2>&1 & php -S localhost:8000 -t web > /dev/null 2>&1 and I update my post to add behat.yml config file. — Benjamin Lazarecki, Oct 07 '13 at 21:06
hello @BenjaminLazarecki can you please update this topic? i tried above but it didn't work for me wondering if there is a better way to solve this now. — Luis Lopes, Jul 05 '16 at 09:47

phantomjs is a headless browser, therefore all dialogs are not show and cannot be interacted with. A solution is to rewrite widnow.confirm and window.alert with your own functions that return pre-defined values.

Since a scenario runs within the same driver, it is perfectly safe to overwrite native methods with pre-defined return values (you will not have a situation where you really need to see a window within the same scenario). Moreover, it is safe to call these step definitions multiple times within a single scenario to flip returned value.

/**
 * @When I accept confirmation dialogs
 */
public function acceptConfirmation() {
  $this->getSession()->getDriver()->executeScript('window.confirm = function(){return true;}');
}

/**
 * @When I do not accept confirmation dialogs
 */
public function acceptNotConfirmation() {
  $this->getSession()->getDriver()->executeScript('window.confirm = function(){return false;}');
}

Scenario example:

Scenario: Removal of something with confirmation dialog
Given I accept confirmation dialogs
And I click a ".mylink" element
And I wait for AJAX to finish
And I should not see a ".some-removed-element" element

I updated my "Selenium2Driver.php" with the following:

public function acceptAlert()
{
$this->wdSession->accept_alert();
}

This makes the accept_alert() available for the driver.

So in the script, you could do something line this to accept the alert.

$this->getSession()->getDriver()->acceptAlert();

Note that I'm using the RawMinkContext not the native MinkContext
