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->findElement(WebDriverBy::tagName('option'));
    
    # select the options
    foreach ($allOptions as $option) {
      echo "Value is:" . $option->getAttribute('value);
      $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();
