How to Run Selenium Test on Firefox?

One of the key features of Selenium is its ability to run tests on multiple browsers, including Firefox. In this article, we will walk through the steps required to run Selenium test on Firefox.

Steps to Run Selenium Test on Firefox

Step 1: Install Firefox

The first step in running Selenium tests on Firefox is to install the browser on your system. Firefox can be downloaded from the official Mozilla website and is available for Windows, Mac, and Linux operating systems.

Step 2: Install Selenium WebDriver

Once Firefox is installed, the next step is to install the Selenium WebDriver. WebDriver is a tool that allows Selenium to interact with the Firefox browser. WebDriver can be downloaded from the official Selenium website and is available for various programming languages such as Java, Python, Ruby, etc.

Step 3: Configure Firefox and Selenium WebDriver

Before running Selenium tests on Firefox, we need to configure Firefox and WebDriver to work together. To do this, we need to set the Firefox binary path and the location of the WebDriver executable file.

For example, if you are using Java, the code to configure Firefox and WebDriver would look like this:

System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver");
System.setProperty("webdriver.firefox.bin", "/path/to/firefox");
WebDriver driver = new FirefoxDriver();

The first line sets the location of the WebDriver executable file, while the second line sets the location of the Firefox binary file. The third line creates a new instance of the FirefoxDriver, which can be used to interact with the Firefox browser.

Step 4: Write Selenium Test Script

Once Firefox and WebDriver are configured, we can write Selenium test scripts that automate interactions with the Firefox browser. For example, the following Java code navigates to the Google homepage. Then it searches for the term “Selenium,” and verifies that the search results page is displayed:

WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.com");
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("Selenium");
searchBox.submit();
WebElement searchResults = driver.findElement(By.id("search"));
Assert.assertTrue(searchResults.isDisplayed());

This code creates a new instance of the FirefoxDriver. It then navigates to the Google homepage, finds the search box element, enters the search term “Selenium,”. After that, it submits the search, and verifies that the search results page is displayed.

Step 5: Run Selenium Test on Firefox

Once the Selenium test script is written, we can run it on Firefox using the configured FirefoxDriver. To do this, we simply execute the test script using the programming language of our choice.

For example, if we are using Java, we can execute the test script using the following command:

‘mvn test’

This command will compile and execute the test script. It will open Firefox, navigate to the Google homepage, search for the term “Selenium,” and verify the search results page is displayed.

Conclusion

Running Selenium tests on Firefox is a straightforward process. It requires installing Firefox, configuring Firefox and Selenium WebDriver, writing Selenium test scripts, and executing the tests. By following these steps, testers can automate browser testing on Firefox and ensure that their web applications behave consistently across different browsers and platforms.
