Selenium cheat sheet

   Automate Browser navigations

   driver.get("link");
   driver.navigate().to("link");
   driver.navigate.back();
   driver.navigate.forward();
   driver.navigate.refresh();

   Window Properties

   getWindowHandle();
   getWindowHandles();
   switchTo().window(windowHandle);
   manage().window().maximize();
   manage().window().minimize();
   manage().window().fullScreen();
   manage().window().getSize();
   manage().window().setSize(Dimension);
   manage().window().getPosition();
   manage().window().setPosition(Point);

   Static and Dynamic dropdown

   Static dropdown: 
   WebElement dropdown = driver.findElement();
   Select select = new Select(dropdown);
   select.selectByVisibleText("text");
   select.selectByValue("Value 2");
   select.selectByIndex(3);

   Dynamic dropdown:
   Locate the dropdown and wait for the dropdown options to load 

   WebDriverWait wait = new WebDriverWait(driver.Duration.ofSeconds(10));

   Handling Checkboxes

   WebElement checkbox = driver.findElement();
   checkbox.isSelected();
   checkbox.isEnabled();
   checkbox.isDisplayed();

  Handling multiple checkboxes:

  // Locate all checkboxes using a common locator
  List<WebElement> checkboxes = driver.findElements(By.cssSelector("input[type='checkbox']"));

  // Loop and click each checkbox if not already selected
  for (WebElement checkbox : checkboxes) {
      if (!checkbox.isSelected()) {
          checkbox.click();
      }
  }

  Alerts 

  Alert alert = driver.switchTo().alert();
  alert.accept();     
  alert.dismiss();      
  alert.getText();      
  alert.sendKeys("text");

  Waits

  Implicit wait: 
  driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));

  Explicit wait: 
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
  WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("username")));

  ExpectedConditions.visibilityOfElementLocated(By)
  ExpectedConditions.elementToBeClickable(By)
  ExpectedConditions.presenceOfElementLocated(By)
  ExpectedConditions.alertIsPresent()
  ExpectedConditions.frameToBeAvailableAndSwitchToIt()

  Fluent wait: 
  Wait<WebDriver> wait = new FluentWait<>(driver)
      .withTimeout(Duration.ofSeconds(30))
      .pollingEvery(Duration.ofSeconds(5))
      .ignoring(NoSuchElementException.class);

  WebElement element = wait.until(driver -> driver.findElement(By.id("dynamicElement")));

  Iframes and child windows 

  driver.switchTo().frame(0);

  driver.switchTo().frame("iframeName");

  WebElement iframe = driver.findElement(By.xpath("//iframe[@id='frame1']"));
  driver.switchTo().frame(iframe);

  driver.switchTo().defaultContent(); // back to main page

  driver.switchTo().parentFrame(); // back to immediate parent iframe (if nested)

  Child windows: 

  Store the main window handle
  String mainWindow = driver.getWindowHandle();

  Click to open new window/tab
  driver.findElement(By.id("openWindow")).click();

  Get all window handles
  Set<String> allWindows = driver.getWindowHandles();

  for (String handle : allWindows) {
      if (!handle.equals(mainWindow)) {
          driver.switchTo().window(handle); // switch to child window
          System.out.println("Child Title: " + driver.getTitle());
          // Perform actions
          driver.close(); // close child if needed
      }
  }

  Switch back to main window
  driver.switchTo().window(mainWindow);

  Scrolling

 JavascriptExecutor js = (JavascriptExecutor) driver;
 js.executeScript("window.scrollBy(0, 500)");
 js.executeScript("window.scrollTo(0, document.body.scrollHeight)");
 js.executeScript("window.scrollTo(0, 0)");

 WebElement element = driver.findElement(By.id("elementId"));
 js.executeScript("arguments[0].scrollIntoView(true);", element);

  Handling https certification

 ChromeOptions options = new ChromeOptions();
 options.setAcceptInsecureCerts(true);

 WebDriver driver = new ChromeDriver(options);
 driver.get("https://your-ssl-warning-site.com");

Screenshots

TakesScreenshot ts = (TakesScreenshot) driver;
File src = ts.getScreenshotAs(OutputType.FILE);
File dest = new File("screenshot.png");
FileUtils.copyFile(src, dest);

Automate broken links

Assertions in selenium

Assert.assertEquals(actualTitle, expectedTitle);
Assert.assertTrue(element.isDisplayed());
Assert.assertFalse(driver.getPageSource().contains("Error"));
Assert.assertNotNull(driver.findElement(By.id("logo")));

Handling cookies

Cookie cookie = new Cookie("test_cookie", "123456");
driver.manage().addCookie(cookie);

Set<Cookie> allCookies = driver.manage().getCookies();
Cookie sessionCookie = driver.manage().getCookieNamed("JSESSIONID");
System.out.println(sessionCookie.getValue());
driver.manage().deleteCookieNamed("test_cookie");

Mouse Actions

WebElement menu = driver.findElement(By.id("menu"));
Actions actions = new Actions(driver);
actions.moveToElement(menu).perform();
actions.moveToElement(button).click().perform();
actions.contextClick(element).perform();
actions.doubleClick(element).perform();
actions.clickAndHold(element).perform();
actions.dragAndDrop(source, target).perform();
