Selenium Tutorial 22: Cross Browser Testing with Selenium

Cross Browser Testing with Selenium tutorial explains executing selenium Test cases using different browsers like Mozilla Firefox, Google Chrome and Internet Explorer. Download Browser drivers , instantiate browser drivers and execute Test cases.

Class Notes:
Selenium Class 22: Cross Browser Testing using Selenium WebDriver

1) What is Cross Browser Testing?

Cross Browser Testing is a type of Test to check that our Web Application works as expected in different Browsers.

2) Why Cross Browser Testing?

A web application can be opened in any web browser by the end user, So we need to ensure that the web application will work as expected in all popular browsers.

3) Popular Browsers

a) Google Chrome: It was released in 2008, its market share approximately 68%

b) Mozilla Firefox: It was released in 2004, its market share approximately 19%

c) Internet Explorer: It was released in 1995, its market share approximately 6.5%

4) Working with different Browsers.

> Selenium WebDriver supports Browser compatibility tests on almost every popular browser, including Chrome, Firefox, IE, Opera and Safari.

> The WebDriver API drives the web browser as the real user would drive it.

> By default, Firefox driver comes with selenium-serverstanalone.jar library added.

> For Chrome, IE, Safari, Opera, there are libraries that need to be instantiated externally.

5) How to conduct Cross Browser Testing using Selenium WebDriver?

a) Element Locators - Same for all Browsers.

b) WebDriver Methods/Commands -Same for all Browsers.

c) Programming features - Same for all Browsers.

d) JUnit / TestNG Annotations - Same for all Browsers.

e) Browser Driver - various from one browser to another.

Note: For Mozilla Firefox, just create the driver, For other browsers, libraries that need to be instantiated externally.

f) Inspect Elements -

For Mozilla Firefox -Built in feature Page Inspector,
(Firebug and Firepath)

For Chrome and IE - Built in Developer tools


6) Create Browser Drivers

(For Google Chrome, IE and Other Browsers, download Browser drivers and set path in Selenium Test Scripts)

a) Mozilla Firefox Browser:

WebDriver driverName = new FirefoxDriver();

b) Google Chrome

//Instantiate Chrome Browser driver

System.setproperty("webdriver.chrome.driver", "driver .exe file path");
WebDriver driverName = new ChromeDriver();

c) IE Browser driver

System.setproperty("webdriver.ie.driver", "driver .exe file path");
WebDriver driverName = new InternetExplorerDriver();

7) Create a Test Case and Execute using Mozilla Firefox, Chrome and IE Browsers.

Test Case: Verify Launch Application (Google) functionality in Firefox, Chrome and IE Browsers.

Steps:
i) Launch the Browser

Verification point:
Capture the page Title (Actual) and Compare with Expected.

Expected Page Title:

a) Test Case for Mozilla Firefox Browser

WebDriver driver = new FirefoxDriver();

String PageTitle = driver.getTitle();

if (PageTitle.equals("Google")){
System.out.println("Google Application Launched - Passed");
}
else {
System.out.println("Google Application Not Launched -Failed");
}
driver.close();

b) Test Case for Google Chrome Browser

System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

String PageTitle = driver.getTitle();

if (PageTitle.equals("Google")){
System.out.println("Google Application Launched - Passed");
}
else {
System.out.println("Google Application Not Launched -Failed");
}
driver.close();

c) Test Case for internet Explorer browser

System.setProperty("webdriver.ie.driver", "E:\\IEDriverServer.exe");
WebDriver driver = new InternetExplorerDriver();

String PageTitle = driver.getTitle();

if (PageTitle.equals("Google")){
System.out.println("Google Application Launched - Passed");
}
else {
System.out.println("Google Application Not Launched -Failed");
}
driver.close();

8) Create a Test Case and Execute using Mozilla Firefox, Chrome and IE Browsers Continuously.

public class TestCase1 {
public static WebDriver driver;
public static int browser;
public static String BrowserName;

public static void main(String[] args) {

for (browser = 1; browser <= 3; browser++){
if (browser == 1) {
driver = new FirefoxDriver();
BrowserName = "Mozilla Firefox Browser: ";
}
else if (browser == 2) {
System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");
driver = new ChromeDriver();
BrowserName = "Google Chrome Browser: ";
}
else if (browser == 3){
System.setProperty("webdriver.ie.driver", "E:\\IEDriverServer.exe");
driver = new InternetExplorerDriver();
BrowserName = "Internet Explorer Browser: ";
}

String PageTitle = driver.getTitle();

if (PageTitle.equals("Google")){
+ " - Google Application Launched - Passed");
}
else {
+ " - Google Application Not Launched -Failed");
}
driver.close();
}
}
}

Thank you so much Sir .Its so helpful for everyone because of very clear explanation .

[Gauravkumar]

instead of for loop, we cud just put the test case in a method and could call the method after instanting the each driver.

Sir in latest version firefox firbug is not supporting so for xpath wht we can use.

[rakeshjoshi]

at 1:18:10 its giving error cause in 36 and 39 line you are using BrowserName as some value + google app launched.
but if its never had a value then how can you use it..
it should at least have some string value in it till the compilation time...
then you can use it..

If we have in built feature page inspector for Mozilla Firefox why did you installed Firebug plug-in. Why didn't you used that in built feature in previous classes for inspecting elements?

[rahulk]

thank you for the video sir. please post the notes for this video.
