Agenda Intro on Selenium Tips and Tricks Pitfalls to avoid Ask questions as we go!

Watir? Web Application Testing in Ruby A different open source project that drives browsers for test automation

What is Selenium? A tool to automate browsers! Quick regression testing across many browsers Automate web based admin tasks

Why Selenium over Watir? Choice More widely supported More bindings available

Regression testing! Repetitive test efforts Reproducible tests across many browsers Time consuming

Automation of web based admin tasks! Creation of data Reading of records on the browser Updating of content Deletion of records

What version of Selenium? Don’t use Selenium 1.0 - Selenium IDE Recorder is deprecated Javascript Injection to drive a browser Selenium 2 uses WebDriver http://docs.seleniumhq.org/projects/webdriver/

WebDriver? A platform and language-neutral interface that allows programs or scripts to introspect into, and control the behaviour of, a web browser http://www.w3.org/TR/2013/WD-webdriver- 20130117/

How do I start? Pick a language! Java C# python ruby others supported as well

Pick your browser/driver Firefox Chrome IE Safari many more!

How do I interact with the browser? Dev tools are built-in to browsers Inspect the HTML to glean the locators to use var inputElement = driver.FindElement(By.Name("myButton")); inputElement.Click();

Built-in locators Use these if you can driver.FindElement(By.Name("myName")); driver.FindElement(By.Id("myId")); driver.FindElement(By.ClassName("myClass")); others as well

XPath vs. CSS XPath //div[. ='Some Text of the Div'] CSS table[id='tblBadgeInfo'] thead td Speed considerations?

Tips to avoid headaches…. GUI based tests sometimes thought of as fragile, brittle or unreliable How to prevent your Selenium automation from becoming shelfware

Use unique locators Very difficult if locators are not unique Avoid using index numbers Ask for some name/id/class on UI elements from the development team

Do not use hard coded sleeps Makes test scripts brittle when run on different environments. Thread.Sleep(5000); // Sleep for 5 seconds button.Click();

Use a polling wait Be flexible and return as soon as possible but ignore exceptions

Use WebDriverWait WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); IWebElement myDynamicElement = wait.Until<IWebElement>((d) => { return d.FindElement(By.Id("myButtonId")); });

Use ExpectedConditions Convenience methods on things that are checked often. Use these with WebDriverWait. http://selenium.googlecode.com/git/docs/api/d otnet/html/AllMembers_T_OpenQA_Seleniu m_Support_UI_ExpectedConditions.htm

Use Page Objects Isolate UI elements from the test cases If the UI changes, your tests only need to be modified in a single place - the Page Object that defines the UI Reduces duplicate code

Login Page Object class LoginPage : BasePage { public LoginPage() {} public void Login(string username,string password) { var nameElement = driver.FindElement(By.Name("username")); nameElement .SendKeys(username); var passElement = driver.FindElement(By.Name("password")); passElement .SendKeys(password); var submitButton = driver.FindElement(By.Name("submit")); submitButton.Click(); } }

Login Test Case var loginPage = new LoginPage(); loginPage.Login("user","pass");

Verify your assumptions…. Are you where you think you are? Verify page elements on transitions Clicked links Form submission

Be Generous with your logging Overlogging is better than underlogging Easier to examine output files to see where failures are occurring Especially true for remote execution Use logging to get a trail on most events

Things I like to log URL of the page Timestamp Values used on assertions Values used on comparators Values used on loops

IE Considerations Sometimes click appears to do “nothing” Use SendKeys instead of Click https://www.google.com/webhp?#safe=off&q=i e+click+selenium

SendKeys Code Instead of button.Click(); Use button.SendKeys(Keys.Enter);

Handling Frames Be sure to set the focus to the frame hosting your elements. IWebElement mainFrame = driver.FindElement(By.Name("MainFrame")); driver.SwitchTo().Frame(mainFrame);

Handling Dialogs Javascript alerts Javascript confirm Javascript prompts

Example code try { driver.SwitchTo().Alert(); return true; } catch (NoAlertPresentException) { // Modal dialog not displayed return false; }

Handling Popup windows var windowHandles = driver.WindowHandles; // if handle 0 is the main window then handle 1 is the popup, otherwise the popup is handle 0 var popUp = (windowHandles[0] == mainWindowHandle ? windowHandles[1] : windowHandles[0]); driver.SwitchTo().Window(popUp); <do stuff> driver.SwitchTo().Window(mainWindowHandle );

Not the only answer... Sometimes Selenium can’t do the job. AutoIt can be used as a fall-back. https://www.autoitscript.com/site/autoit/

Advanced Topics Use with Continuous Integration tools Remote control of tests Selenium Grid

Summary Instrument your framework correctly and Selenium tests can be very good for you Don’t be discouraged. Try different things. Investigate to see what Selenium can do for you
