Using selenium web driver to run test on multiple browsers

Question

I\'m trying to run a same test across multiple browsers through for loop but it always run only on Firefox.

bros = [\'FIREFOX\',\'CHROME\',\'INTERNET EXPLORER\']         


        

Answer 1

Have you considered using the composite design pattern to create a CompositeWebDriver that actually runs multiple component WebDriver (such as chrome, gecko,...)? To this end, you would extend the WebDriver class with a new one (e.g. CompositeWebDriver) that just delegates his calls to all the actual WebDrivers.

This could also be done with various instances of RemoteWebDriver as components.

Answer 2

I actually have done this in java, the following works well for me:

...
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
...

DesiredCapabilities[] browsers = {DesiredCapabilities.firefox(),DesiredCapabilities.chrome(),DesiredCapabilities.internetExplorer()};
    for(DesiredCapabilities browser : browsers)
    {
        try{
            System.out.println("Testing in Browser: "+browser.getBrowserName());
            driver = new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub"), browser);
            ...

You will need to adapt this of course if you're writing your tests in a different language, I know it's possible in Java, not sure about otherwise.

Also, I agree with what you're trying to do, I think it is much better to have a class that runs the same tests with different browsers, instead of duplicating code many times over and being inelegant. If you are doing this in Java/other codes, I also highly suggest using a Page Object.

Good luck!

So if I got you right, you have one testcase and want this to be tested against different browsers.

I don't think a loop is a good idea even if it's possible (I don't know atm).

The idea is to be able to test every testcase standalone on the run with a specific browser (thats the JUnit philosophy), not to run all in order to get to that specific browser .

So you need to create a WebDriver with the specific browser and the specific testcase.

I suggest you seperate testcases by creating a testcase-class file for each browser.

Like: FirefoxTestOne.java, IeTestOne.java, ChromeTestOne.java .

Note that you can add multiple firefox tests in the FirefoxTestOne without problems. Theres no guarantee that they will be executed in a particular order through (JUnit philosophy).

For links and tutorials ask google. There are already looooots of examples written.

Answer 4

This way (attached url) worked for me.

The following point is different from the example.

@Parameters
public static List data() {
    return Arrays.asList(new Object[][]{{"firefox"},{"ie"}});
}
@Before
public void setUp() throws Exception {
    System.out.println("browser: " + browser);
    if(browser.equalsIgnoreCase("ie")) {
        System.setProperty("webdriver.ie.driver", "IEDriverServer64.exe");
        driver = new InternetExplorerDriver();
    } else if(browser.equalsIgnoreCase("firefox")) {
        driver = new FirefoxDriver();

Answer 5

As Coretek said you need multiple webdriver instances. You will need to run the selenium-server .jar file and provide each one with an argument specifying the browser you want that instance of the server to run.

The argument for Internet Explorer is *iexplore, the argument for firefox is *firefox and the argument for chrome is *chrome. These are -forcedBrowserMode arguments. Otherwise selenium won't know what it should be running against. You may need to use *iexploreProxy for your tests, sometimes it works better than the *iexplore mode.

You can use TestNG for this combination of selenium + testng gives you a batter result for this just by adding parameters attribute you can do this
