Using selenium web driver to run test on multiple browsers - browser

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']
for bro in bros:
print "Running "+bro+"\n"
browser = webdriver.Remote(
command_executor='http://10.236.194.218:4444/wd/hub',
desired_capabilities={'browserName': bro,
'javascriptEnabled': True})
browser.implicitly_wait(60000)
browser.get("http://10.236.194.156")
One interesting observation; when I include the parameter platform: WINDOWS it's running only on Internet Explorer.
Does Selenium Webdriver works this way or my understanding is wrong?

Answer 1

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!

Answer 2

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 3

You will have to generate multiple test classes (or webdriver instances) with the chosen browsers.
A Webdriver is defined with one browser.

Answer 4

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.

Answer 5

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 6

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

Answer 7

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.
