Cheat sheet for using php webdriver (facebook/webdriver).

Webdriver PHP API workthough

  • Open a browser

    # start an instance of firefox with selenium-webdriver
    
    $browser_type = 'firefox'
    $host = 'http://localhost:4444/wd/hub'
    
    $capabilities = array(\WebDriverCapabilityType::BROWSER_NAME => $browser_type);
    $driver = RemoteWebDriver::create($host, $capabilities);
    
    $browser_type
    # :firefox => firefox
    # :chrome  => chrome
    # :ie      => iexplore
    
  • Go to a specified URL

    $driver->get('http://google.com');
    $driver->navigate()->to('http://google.com');
    

    'NOTE' -- the WebDriver may not wait for the page to load, you'd better using explicit and implicit waits.

  • Locating Elements

    • 'findElement(WebDriverBy $by)' -- Find the first element matching the given arguments.

    • 'findElements(WebDriverBy $by)' -- Find all elements matching the given arguments

    • 'WebDriverBy' -- Class with static methods for selecting elements using different mechanisms.

      • 'WebDriverBy
        • 'class name'
        • 'css selector'
        • 'id'
        • 'name'
        • 'link text'
        • 'partial link text'
        • 'tag name'
        • 'xpath'
    • Finding Element By ID

      # example html
      # <input id="q">...</input>
      	
      $element = $driver->findElement(WebDriverBy::id("q"));
      
    • By Class Name

      # example html
      # <div class="highlight-java" style="display: none; ">...</div>
      
      $element = $driver->findElement(WebDriverBy::className('highlight-java'));
      
    • By Tag Name

      # example html
      # <div class="highlight-java" style="display: none; ">...</div>
      
      $element = $driver->findElement(WebDriverBy::tagName("div"));
      
    • By Name

      # example html
      # <input id="q" name='search' type='text'>…</input>
      
      $element = $driver->findElement(WebDriverBy::name('search'));
      
    • By Link Text

      # example html
      # <a href="http://www.google.com/search?q=cheese">cheese</a>
      
      $element = $driver->findElement(WebDriverBy::linkText("cheese"));
      
    • By Partial Link Text

      # example html
      # <a href="http://www.google.com/search?q=cheese">search for cheese</a>
      
      $element = $driver->findElement(WebDriverBy::partialLinkText("chee"));
      
    • By XPath

      # example html
      # <ul class="dropdown-menu">
      #   <li><a href="/login/form">Login</a></li>
      #   <li><a href="/logout">Logout</a></li>
      # </ul>
      
      $element = $driver->findElement(WebDriverBy::xpath('//a[@href='/logout']'));
      
      • NOTE -- When using Element#findElement with WebDriverBy::xpath, be aware that,

        • webdriver follows standard conventions: a search prefixed with "//" will search the entire document, not just the children of this current node.
        • Use ".//" to limit your search to the children of the receiving Element.
    • By CSS Selector

        # example html
        # <div id="food">
        #   <span class="dairy">milk</span>
        #   <span class="dairy aged">cheese</span>
        # </div>
      
        $element = $driver->findElement(WebDriverBy::cssSelector('#food span.dairy'));
      
  • Element's operation

    • Button/Link/Image

      $element = $driver->findElement(WebDriverBy::id('BUTTON_ID'))->click();
      
    • Text Field

      # input some text
      $driver->findElement(WebDriverBy::id('BUTTON_ID'))->click();
      $driver->getKeyboard()->sendKeys('InputText');
      
      # send keyboard actions, press `cmd+a` & `delete`
      $driver->getKeyboard()
        ->sendKeys(array(
          WebDriverKeys::COMMAND, // Use control on non-mac computers.
          'a',
        ));
      
      $driver->getKeyboard()
        ->sendKeys(array(
          WebDriverKeys::BACKSPACE,
        ));
      

      *'Note' -- /RemoteWebElement->clear() will clear text from a textarea or a text input.

    • Checkbox/Radio

      # check if it is selected
      $driver->findElement(WebDriverBy::id('CheckBox'))->isSelected();
      
      # select the element
      $driver->findElement(WebDriverBy::id('CheckBox'))->click();
      
      # deselect the element
      $driver->findElement(WebDriverBy::id('CheckBox'))->clears();
      
    • Select

      # get the select element	
      $select = $driver->findElement(WebDriverBy::tagName('select'));
      
      # get all the options for this element
      $allOptions = $select->findElements(WebDriverBy::tagName('option'));
      
      # select the options
      foreach ($allOptions as $option) {
        echo "Value: {$option->getAttribute('value')} Text: {$option->getText()}"
        $option->click();
      }
      
    • visibility

      $driver->findElement(WebDriverBy::id('element'))->isDisplayed();
      
    • get text

      $driver->findElement(WebDriverBy::id('element'))->getText();
      
    • get attribute

      $driver->findElement(WebDriverBy::id('element'))->getAttribute('class');
      
  • Driver's operation

    • execute javascript

        $driver->executeScript("return window.location.pathname");
      
    • wait for a specific element to show up

        # set the timeout to 20 seconds, and the time in interval to 1000 ms
      
        $driver->wait(20, 1000)->until(
            WebDriverExpectedCondition::titleIs('WebDriver Page')
        );
      
    • implicit waits

    An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available

    	# set the timeout for implicit waits as 10 seconds
    	$driver->manage()->timeouts()->implicitlyWait = 10
    	
    	$driver->get("http://somedomain/url_that_delays_loading");
    	$element = $driver->findElement(WebDriverBy::id('some-dynamic-element'));
    
    • switch between frames

        # switch to an iframe
        $driver->switchTo()->frame(/WebDriverElement('the id or the name of the frame"some-frame" # name or id'));
      
        # switch back to the main document
        $driver->switchTo()->defaultContent();
      
    • swich between windows

        #TODO: Add examples.
      
    • handle javascript dialog

        # get the alert
      
        $a = $driver->switchTo->alert();
      
        # operation on the alert
      
        if ($a->getText == 'A value you are looking for') {
          a->dismiss();
        }
        else {
          a->accept();
        }
      
  • Cookies

    • Delete cookies

        # You can delete cookies in 2 ways
        # By name
        $driver->manage()->deleteCookieNamed('CookieName');
      
        # Or all of them
        $driver->manage()->deleteAllCookies();
