WebDriver’s most popular Commands

Selenium WebDriver is like a magic wand to automation tester to test the web application. Selenium WebDriver has not only  made automation more Object oriented through it OOPs API  but it has also solve the  the most complaining performance of browser launching in Selenium 1.0 and the most important thing that has given a panacea to automation engineers’ hand is its ability to Single Host origin policy.

Selenium WebDriver has left more impact on functional test coverage, like the file upload or download, pop-ups and dialog’s barrier

Today I am going to post most common functions used in Selenium WebDriver to make a journey of automation testing through WebDriver

      1. IsElementPresent/Text Present  function in Selenium WebDriver
        1. Finding elements by using function that take argument of By classprivate boolean isElementPresent(WebDriver driver, By by)
          try{
          driver.findElement(by);
          return true;
          }
          catch(Exception e)
          {
          return false;
          }
          }
        2. Using the size to decide whether element is there or not
          if(driver.findElements(Locator).size()>0
          {
          return true
          }else
          {
          return false
          }
          }
        3. Finding the text using the PageSource
          driver.PageSource.Contains("TEXT that you want to see on the page");

      2. Finding WebElement  by using various locators in WebDriver
        1. Using ID  WebElement welement = driver.findElement(By.id("Id from webpage"));
        2. Using Name  WebElement welement = driver.findElement(By.name("Name of WebElement"));
        3. Using Tag Name  WebElement welement = driver.findElement(By.tagName("tag name"));
        4. Using Xpath  WebElement welement = driver.findElement(By.xpath("xpath of  webElement"));
        5. Using CSS  WebElement welement = driver.findElement(By.CSS("CSS locator path"));
        6. Using LinkText  WebElement welement = driver.findElement(By.LinkText("LinkText"));
    1. Fetching pop-up message in Selenium-WebDriver
      this is the function that would help you in fetching the message

      public static String getPopupMessage(final WebDriver driver) {
      String message = null;
      try {
      Alert alert = driver.switchTo().alert();
      message = alert.getText();
      alert.accept();
      } catch (Exception e) {
      message = null;
      }
      System.out.println("message"+message);
      return message;
      }
    2. Canceling pop-up in Selenium-WebDriver
      public static String cancelPopupMessageBox(final WebDriver driver) {
      String message = null;
      try {
      Alert alert = driver.switchTo().alert();
      message = alert.getText();
      alert.dismiss();
      } catch (Exception e) {
      message = null;
      }
      return message;
      }
    1. Inserting string in Text Field in Selenium-WebDriver
      public static void insertText(WebDriver driver, By locator, String value) {
      WebElement field = driver.findElement(locator);
      field.clear();
      field.sendKeys(value);
      }
    2. Reading ToolTip text in in Selenium-WebDriver
      public static String tooltipText(WebDriver driver, By locator){
      String tooltip = driver.findElement(locator).getAttribute("title");
      return tooltip;
      }
    3. Selecting Radio Button in Selenium-WebDriver

      public static void selectRadioButton(WebDriver driver, By locator, String value){ List select = driver.findElements(locator);
      for (WebElement element : select)
      {
      if (element.getAttribute("value").equalsIgnoreCase(value)){
      element.click();
      }
      }
    4.  Selecting CheckBox in Selenium-WebDriver

      public static void selectCheckboxes(WebDriver driver, By locator,String value)
      {
      List abc = driver.findElements(locator);
      List list = new ArrayListArrays.asList(value.split(",")));
      for (String check : list){
      for (WebElement chk : abc){
      if(chk.getAttribute("value").equalsIgnoreCase(check)){
      chk.click();
      }}}}
    5. Selecting Dropdown in Selenium-WebDriver
      public static void selectDropdown(WebDriver driver, By locator, String value){
      new Select (driver.findElement(locator)).selectByVisibleText(value); }
    6. Selecting searched dropdown in Selenium-WebDriver
      public static void selectSearchDropdown(WebDriver driver, By locator, String value){
      driver.findElement(locator).click();
      driver.findElement(locator).sendKeys(value);
      driver.findElement(locator).sendKeys(Keys.TAB);
      }
    7. Uploading file using  Selenium-WebDriver
      public static void uploadFile(WebDriver driver, By locator, String path){
      driver.findElement(locator).sendKeys(path);
      }
    8. Downloading file in Selenium-WebDriver
      Here we will click on a link and will download the file with a predefined name at some specified location.
      public static void downloadFile(String href, String fileName) throws Exception{
      URL url = null;
      URLConnection con = null;
      int i;
      url = new URL(href);
      con = url.openConnection();
      // Here we are specifying the location where we really want to save the file.
      File file = new File(".//OutputData//" + fileName);
      BufferedInputStream bis = new BufferedInputStream(con.getInputStream());
      BufferedOutputStream bos = new BufferedOutputStream(
      new FileOutputStream(file));
      while ((i = bis.read()) != -1) {
      bos.write(i);
      }
      bos.flush();
      bis.close();
      }
    9. Handling multiple Pop ups 
      read  Handling Multiple Windows in WebDriver
    10. Wait() in Selenium-WebDriver
      1. Implicit Wait :
        driver.manage.timeouts().implicitlyWait(10,TimeUnit.SECONDS);
      2. Explicit Wait:WebDriverWait wait = new WebDriverWait(driver,10);
        wait.until(ExpectedConditons.elementToBeClickable(By.id/xpath/name("locator"));
      3.  Using Sleep method of java
        Thread.sleep(time in milisecond)
    11. Navigation method of WebDriver Interface

      1. to() method (its a alternative of get() method)
        driver.navigate().to(Url);
        This will open the URL that you have inserted as argument
      2. back() – use to navigate one step back from current position in recent history syntax == driver.navigate().back();
      3. forward() – use to navigate one step forward in browser history driver.navigate().forward();
      4. refresh() – This will refresh you current open url driver.navigate().refresh();
    12. Deleting all Cookies before doing any kind of action  driver.manage().deleteAllCookies();
      This will delete all cookies
  1. Pressing any Keyboard key using Action builder class of WebDriver
    WebDriver has rewarded us with one class Action to handle all keyboard and Mouse action. While creating a action builder its constructor takes WebDriver as argument. Here I am taking example of pressing Control key
    Actions builder = new Actions(driver);
    builder.keyDown(Keys.CONTROL).click(someElement).click(someOtherElement).keyUp(Keys.CONTROL).build().perform();
    When we press multiple keys or action together then we need to bind all in a single command by using build() method and perform() method intend us to perform the action.
    In the same way you can handle other key actions.
  2. Drag and Drop action in Webdriver
    In this we need to specify both WebElement  like Source and target and for draganddrop Action class has a method with two argument so let see how it normally look like
    WebElement element = driver.findElement(By.name("source"));
    WebElement target = driver.findElement(By.name("target"));
    (new Actions(driver)).dragAndDrop(element, target).perform();
