Testing 'prompt' popups

[Mike]

Hi, I'm trying to test a page that has a javascript prompt popup. I've read the topic
https://groups.google.com/forum/#!topic/behat/Cc6OcObVWnE and I'm utilising the code by benjamin lazarecki (https://gist.github.com/2888851)
The scenario is as follows
 features/behat/behat-test-window-alert.feature

Feature: For other tests to work, Behat must be able to type into a popup
@behat
  Background:                                                                   
    Given I am logged in as the test user

@javascript
  Scenario: Open and switch to a new window                       
    When I go to "/utils/subwindowwithpassword"

    When I press "Enter"
    And I wait 5 seconds
    Then I should see "Please enter your password" in popup
    When I fill "1234" in popup
    And I confirm the popup
    Then I should see "You're in!"

The javascript is as follows:
    var message = "no message";
    function enter() {
        var pass = prompt("Please enter your password","type here");
        if ( pass == "1234") {
            message = "You're in!";
        } else {
            message = "Go away!";
        }
        var elem = document.getElementById("message");
        elem.innerHTML = message;
    }
   

All the steps 'work' (show in green) except the last one. The popup flashes up and disappears, too quick to see if the "1234" goes in. Any attempt to $this->getSession()->wait(5000); will complain about a modal dialog ad fail straight away. If in the javascript I say if ( pass == "type here") then the last step passes.

Is anyone getting this sort of scenario to work?

Some more information which may be useful: Looking at the output of Selenium2 standalone server:
11:24:21.409 INFO - Executing: [get alert text] at URL: /session/fc53eaa6-0f7c-4891-8752-65c1756d54f3/alert_text)
11:24:21.504 INFO - Done: /session/fc53eaa6-0f7c-4891-8752-65c1756d54f3/alert_text
11:24:21.517 INFO - Executing: [accept alert] at URL: /session/fc53eaa6-0f7c-4891-8752-65c1756d54f3/accept_alert)
11:24:21.541 INFO - Done: /session/fc53eaa6-0f7c-4891-8752-65c1756d54f3/accept_alert

There is no representation of post_Alert in there, so I guess this webdriver doesn't support it? According to the Selenium docs it should. So, I'm asking if anyone has used this sucessfully?

 You can use this function taken from the Behatch extension to insert a breakpoint so you can inspect what happens at a given point:

   /**
     * Pauses the scenario until the user presses a key. Useful when debugging a scenario.
     *
     * @Then /^(?:|I )put a breakpoint$/
     */
    public function iPutABreakpoint()
    {
        fwrite(STDOUT, "\033[s    \033[93m[Breakpoint] Press \033[1;93m[RETURN]\033[0;93m to continue...\033[0m");
        while (fgets(STDIN, 1024) == '') {}
        fwrite(STDOUT, "\033[u");

        return;
    }

or you can print out debugging information using:

$this->printDebug($str);

Cracked it!

OK, so I had written a java program linked directly to Selenium and used "Alert alert = driver.switchTo().alert(); alert.sendKeys(text.toString());" to at least show that it wasn't a limitation of Selenium itself or of it's support for the browser.

Vanille's breakpoint led me to the solution: I put one just before my "When I fill "1234" in popup" and was able to "type" into the popup with the following from the terminal:

curl -X POST -d "1234" http://localhost:4444/wd/hub/session/cbac2503-65c9-4f20-ab15-2483e372a3b6/alert_text/

But by the error messages this command to Selenium was expecting a parameter in JSON format; documentation confirms this (http://code.google.com/p/selenium/wiki/JsonWireProtocol#Commands)

OK then, let's try this:

curl -X POST -d "{\"text\": \"1234\"}" http://localhost:4444/wd/hub/session/cbac2503-65c9-4f20-ab15-2483e372a3b6/alert_text

Success!

After some looking around in the code, the thing is that if HTTP method is POST and the arguments/parameters are an array then it will JSON-encode them. So if I change Bejamin's original setPopupText to this:

    public function setPopupText($message)
    {
        $this->getSession()->getDriver()->getWebDriverSession()->postAlert_text(array("text" => $message));
    }

Then it works as expected!
