Testing Multiple Browsers

22 Apr 2014

Web Applications normally need to be tested on multiple browsers. We would like to write a single test suite and run it on different browsers.

We can provide the browser we want the test to run on with @Parameters annotation in TestNG. In this case the defaul browser will be firefox.

@Parameters({ "browser" })
@BeforeMethod
public void setUp(@Optional("firefox") String browser) throws Exception {
}

Now we can configure TestNG with an xml file.

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
  
<suite name="SeleniumGrid" verbose="1" parallel="tests" thread-count="4">
  <test name="firefox">
    <parameter name="browser" value="firefox"/>
    <classes>
      <class name="jesg.SeleniumGridTest"/>
    </classes>
  </test>
  <test name="chrome">
    <parameter name="browser" value="chrome"/>
    <classes>
      <class name="jesg.SeleniumGridTest"/>
    </classes>
  </test>
  <test name="phantomjs">
    <parameter name="browser" value="phantomjs"/>
    <classes>
      <class name="jesg.SeleniumGridTest"/>
    </classes>
  </test>
</suite>

To run the test with a different browser we set the browser parameter.

When selenium server is running locally the test suite can be run with mvn test.

public class SeleniumGridTest {
    private WebDriver driver;
    private Capabilities capabilities;
    private Map<String, Capabilities> browserConfig = new HashMap<String, Capabilities>();

    @BeforeTest
    public void init() {
        browserConfig.put("firefox", DesiredCapabilities.firefox());
        browserConfig.put("chrome", DesiredCapabilities.chrome());
        browserConfig.put("phantomjs", DesiredCapabilities.phantomjs());
    }

    @Parameters({ "browser" })
    @BeforeMethod
    public void setUp(@Optional("firefox") String browser) throws Exception {
        RemoteWebDriver remoteDriver = new RemoteWebDriver(
                browserConfig.get(browser));
        driver = remoteDriver;
        capabilities = ((HasCapabilities) remoteDriver).getCapabilities();
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
    }

    @AfterMethod
    public void tearDown() throws Exception {
        driver.quit();
    }

    @Test()
    public void verifyLinks() {
        driver.get("https://www.google.com/");
        System.out.println("Browser: " + capabilities.getBrowserName()
                + " version: " + capabilities.getVersion() + 
                " platform: " + capabilities.getPlatform() + 
                " title: " + driver.getTitle());
    }

}
