10. HOW?
...things get clearer when you can see them :)

11. Tech and Tools

13. Let’s get started with
Selenium
...lets see some examples...

14. Why Selenium?

15. ● OS independent
● Multiple languages Python, PERL, RUBY, PHP, .NET(C#), Java
● Supports lot many browsers
● Open source and have a good community base
● Robust methods to locate elements

16. Demo - try it yourself!

17. Automate a scenario using
Selenium IDE

18. Scenario: Search an Element
❏Open an URL
❏Search for an element
❏Repeat the test in Selenium IDE

19. Initiate a Browser through
Selenium

20. Open application through Firefox and Chrome
Chrome:
System.setProperty("webdriver.chrome.driver", "/<path to chrome driver>/chromedriver");
String url = "http://localhost:3000";
WebDriver driver = new ChromeDriver();
driver.get(url);
Firefox:
System.setProperty("webdriver.gecko.driver","/Users/shivalis/Downloads/geckodriver");
String url = "http://localhost:3000";
WebDriver driver = new FirefoxDriver();
driver.get(url);

21. Start Interacting with an
application

22. Scenario: Login to Spree e-Commerce Application
Find By ID
System.setProperty("webdriver.chrome.driver", "/Users/shivalis/Downloads/chromedriver");
String url = "http://localhost:3000";
WebDriver driver = new ChromeDriver();
driver.get(url);
// Find By Id
WebElement login_icon = driver.findElement(By.id("link-to-login"));
login_icon.click();
WebElement user_name = driver.findElement(By.id("spree_user_email"));

23. By Name and XPath
// Find By Name
WebElement pswd = driver.findElement(By.name("spree_user[password]"));
user_name.sendKeys("xt@xt.com");
pswd.sendKeys("xtxtxt");
// Find By Xpath
WebElement submit_button =
driver.findElement(By.xpath("//*[@id='new_spree_user']/p[2]/input"));
submit_button.submit();

24. Scenario: Search for an
element and add it to cart

25. @Test
public void searchForAnElement()
{
System.setProperty("webdriver.chrome.driver", "/Users/shivalis/Downloads/chromedriver");
String url = "http://localhost:3000";
WebDriver driver = new ChromeDriver();
driver.get(url);
// Find By Id
WebElement search_box = driver.findElement(By.id("keywords"));
search_box.sendKeys("Bag");
WebElement search_bar = driver.findElement(By.xpath("//*[@id="search-bar"]/form/input[2]"));
search_bar.click();
// Find multiple elements
List<WebElement> products = driver.findElements(By.xpath("//*[@id="products"]/li"));
System.out.println(products.size());
Assert.assertEquals("Size doesn't match ",2, products.size());
}

26. Add Assertion to your
Scenario

27. Closing notes
...time flies when you’re automating tests...

28. Suggestions
● Automate as you go
● Identify automatable
candidates
● Identify levels to Implement
Automation
● Cross role pairing
