About Me

Testing Pyramid

Never forget the pyramid!

• Target audience is for people who have experience using Selenium WebDriver

• At BuildDirect we use:• Selenium WebDriver for desktop

• http://www.seleniumhq.org• Appium for mobile/tablet

• http://appium.io• My experience is with C# bindings only. Other languages should be similar.

Background

• Methods to increase code re-use

• Learn some differences between various browsers

• Learn from BD experiences

Goals of this Talk

Statement

• I do not want my test runs interrupted by any OS level dialog windows

Sample

Problem

• iOS automatically downloads and prompts for update

iOS

Workaround

• Disable it!

iOS

Statement

• I want to run custom javascript during my test to do different actions (like open a new browser window).

Sample

Problem

• iOS restricts this due to security reasons

iOS

((IJavaScriptExecutor)Driver).ExecuteScript("window.open();");

Workaround

• Skip tests that run on iOS devices

or

• If you’re running tests against a simulator, Appium has a capability option to allow Safari to open new browsers

iOS

var dc = DesiredCapabilities.IPhone(); dc.SetCapability(“safariAllowPopups", “true");

Statement

• I want to send “action” keys to a textbox to cause a Javascript blur event

Sample

Problem

• Some keys will send an emoji character instead

• Tab will send

iOS

Driver.FindElement(By.Id(“username")).SendKeys(Keys.Tab);

Workaround

• We were using the Keys.Tab to cause a Javascript blur event

• We were able to do the same by changing focus to another element

iOS

Statement

• I want to easily interact with elements on Android devices

Sample

Problem

• Sometimes, elements cannot be interacted with if they are not in the view

Android

Driver.FindElement(By.Id("loginButton")).Click();

Workaround

• Add scrolling functionality to prior to clicking on element

• Install a keyboard app called “Null Keyboard” that permanently hides the keyboard

• Appium has a method to close the keyboard

Android

var ele = Driver.FindElement(By.Id("loginButton"));             var js = (IJavaScriptExecutor) Driver;             js.ExecuteScript("arguments[0].scrollIntoView(true);", ele);         

Statement

• I want to click on the element so that I can do actions on IE browser

Sample

Problem

• Sometimes IE will not execute the click properly and the view will not change

Internet Explorer

Driver.FindElement(By.Id("loginButton")).Click();

Workaround

• Wrap the Click() method and have it retry if first click failed

Internet Explorer

driver.FindElement(elementToClick).Click();

// element still on screen, retry only when testing using IE             if (driver.FindElement(elementToClick) != null && driver is InternetExplorerDriver){                  driver.FindElement(elementToClick).Click();             }

Statement

• I want to be able to delete all the cookies so my browser has a clean session before running the test

Sample

Problem

• IE cannot manipulate httpOnly cookies

Internet Explorer

Driver.Manage().Cookies.DeleteAllCookies();

Workaround

• When instantiating the InternetExplorerDriver we can set options to ensure that the session is cleared

• Note that his means you have to start a new browser for each test

Internet Explorer

var opts = new InternetExplorerOptions                     {                          EnsureCleanSession = true                         };                     

Driver = new InternetExplorerDriver(opts);

Statement

• I want to write my automation once so I don’t have to have special code paths for different device views

Sample

Problem

• A responsive view might have multiple elements with the same locator value and your FindElement() might not get the one you want

Responsive Design

Driver.FindElement(By.Id("loginButton"));

Workaround

• Use the same locator value for all the designs

• From the test make sure your FindElement searches for Displayed == true elements only

• Add special helper variables to help determine if you are in mobile, tablet, or desktop view

• Limit use of these though as it could increase test maintenance work

Responsive Design

Driver.FindElements(By.Id("loginButton")).First(e => e.Displayed);

Statement

• I am running tests remotely and want screenshots during test run for debugging

Problem

• Screenshots can increase test run time. Some devices/browsers more than others

• IE takes a full webpage by taking multiple screenshots and combining them

• Android/iOS devices are slow when taking screenshots

Screenshots

Workaround

• Only take screenshots on failed steps

• Have a way to easily toggle screenshots on or off

Screenshots

• Each browser has its own quirks

• Be flexible in your automation design

• Limit the amount of browser specific code
