Browser Arguments:

–headless

To open browser in headless mode. Works in both Chrome and Firefox browser

–start-maximized

To start browser maximized to screen. Requires only for Chrome browser. Firefox by default starts maximized

–incognito

To open private chrome browser

–disable-notifications

To disable notifications, works Only in Chrome browser

Example:

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--start-maximized");
chromeOptions.addArguments("--disable-notifications");
chromeOptions.addArguments("--incognito");

Alternative

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--incognito","--start-maximized","--headless");

Launch URL

driver.get(url)

Retrieve Browser Details:

driver.getTitle();
driver.getWindowHandle();
driver.getWindowHandles();
driver.getCurrentUrl();
driver.getPageSource();

Navigation

driver.get(url);
driver.navigate().to(url);
driver.navigate().to(new URL(url));
driver.navigate().back();
driver.navigate().forward();
driver.navigate().refresh();

Locating Elements

By id

<input id=”login” type=”text” />

element = driver.findElement(By.id(“login”))

By Class Name

<input class=”gLFyf” type=”text” />

element = driver.findElement(By.className(“gLFyf”));

By Name

<input name=”z” type=”text” />

element = driver.findElement(By.name(“z”));

By Tag Name

<div id=”login” >…</div>

element = driver.findElement(By.tagName(“div”));

By Link Text

<a href=”#”>News</a>

element = driver.findElement(By.linkText(“News”));

By XPath

<form id=”login” action=”submit” method=”get”>

Username: <input type=”text” />

Password: <input type=”password” />

</form>

element = driver.findElement(By.xpath(“//form[@id='login']/input”));

By CSS Selector

<form id=”login” action=”submit” method=”get”>

Username: <input type=”text” />

Password: <input type=”password” />

</form>

element = driver.findElement(By.cssSelector("input.username"));

Clicking / Input text

Clicking button

chromedriver.findElement(By.className("gLFyf")).click();

Send Text

chromedriver.findElement(By.className("gLFyf")).send_keys("hello");

Waits

Implicit Waits

An implicit wait instructs Selenium WebDriver to poll DOM for a certain amount of time, this time can be specified, when trying to find an element or elements that are not available immediately.

driver = webdriver.Chrome();
driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS) ;
driver.get("https://www.google.com");
driver.findElement(By.name("q")).click();

Explicit Waits

Explicit wait make the webdriver wait until certain conditions are fulfilled . Example of a wait

new WebDriverWait (chromeDriver,10).until(ExpectedConditions.presenceOfElementLocated(By.name("q")));

List of explicit waits

• alertIsPresent()
• elementSelectionStateToBe()
• elementToBeClickable()
• elementToBeSelected()
• frameToBeAvaliableAndSwitchToIt()
• invisibilityOfTheElementLocated()
• invisibilityOfElementWithText()
• presenceOfAllElementsLocatedBy()
• presenceOfElementLocated()
• textToBePresentInElement()
• textToBePresentInElementLocated()
• textToBePresentInElementValue()
• titleIs()
• titleContains()
• visibilityOf()
• visibilityOfAllElements()
• visibilityOfAllElementsLocatedBy()
• visibilityOfElementLocated()

Loading a list of elements like li and selecting one of the element

 public void test1() {

	  

	  String searchButton_css = "button.btn.Searchbox__searchButton.Searchbox__searchButton--active[data-selenium='searchButton']";

	  String inputDestination_css = "input[data-selenium='textInput']";

	  String suggestedDestinationList_css = "ul.AutocompleteList";

	  String stringBali = "Bali";

	  

	  System.setProperty("webdriver.chrome.driver", "//Users//ivantay//WebDrivers//chrome//mac//chromedriver");

	  driver=new ChromeDriver ();

	  driver.get(url);

	  

	  new WebDriverWait (driver,10).until(ExpectedConditions.presenceOfElementLocated(By.cssSelector(searchButton_css)));

	  driver.findElement(By.cssSelector(inputDestination_css)).sendKeys("Bali Indonesia");

	  

	  new WebDriverWait (driver,10).until(ExpectedConditions.presenceOfElementLocated(By.cssSelector(suggestedDestinationList_css)));

	  WebElement items = driver.findElement(By.cssSelector(suggestedDestinationList_css));

	  List <WebElement> elementsList = items.findElements(By.tagName("li"));

	  

	  for (WebElement item : elementsList){

		  

		  if (item.getText().contains(stringBali)){

			  

			  item.click();

			  break;

		  }

		  

	  }

	  

  }

Read Attribute

System.out.println("Title of searchbar : "+ chromedriver.findElement(By.name("q")).getAttribute("jsaction"));

Get CSS

driver = webdriver.Chrome();

// open website
driver.get("https://google.com");

// get the css value
String cssValue = driver.findElement(By.name("q")).getCssValue("font-size");
System.out.println("font size searchbar : "+ cssValue);

CSS values varies on different browser, you may not get same values for all the browser.

Capture Screenshot

public void captureSnapShot(WebDriver driver,String path) throws Exception{

        //Convert web driver object to TakeScreenshot

        TakesScreenshot scrShot =((TakesScreenshot)driver);

        //Call getScreenshotAs method to create image file

                File srcFile=scrShot.getScreenshotAs(OutputType.FILE);

            //Move image file to new destination

                File destFile=new File(path);

                //Copy file at destination

                FileUtils.copyFile(srcFile, destFile);

    }

This will saved the file as in the path of destFile.

isSelected()

isSelected() method in selenium verifies if an element (such as checkbox) is selected or not. isSelected() method returns a boolean.

driver = webdriver.Chrome();

// open website
driver.get("https://google.com.sg");

// get css value
boolean isSelected = driver.findElement(By.xpath("//input[@id='selected']")).isSelected();
System.out.println("Is checkbox selected : ", isSelected);

isDisplayed()

isDisplayed() method in selenium webdriver verifies and returns a boolean based on the state of the element (such as button) whether it is displayed or not.

driver = webdriver.Chrome();

// open website
driver.get("https://google.com");

// get css value
boolean isDisplayed = driver.findElement(By.name("q")).isDisplayed();
System.out.println("Is Searchbar Displayed : ", isDisplayed);

isEnabled()

is_enabled() method in selenium python verifies and returns a boolean based on the state of the element (such as button) whether it is enabled or not.

driver = webdriver.Chrome();

// open website
driver.get("https://google.com");

// element enabled
boolean isEnabled = driver.findElement(By.name("q")).isEnabled();
System.out.println("Is searchbar enabled : ", isEnabled);
