Hence, to execute Selenium script on the Firefox, we need to set the path to Firefox driver executable. Therefore, it implies that it is not able to locate the driver required to run the automation on the desired browser. The error clearly says that path to driver executable should be set. Note: If you have not yet executed the script, you can do so by doing the right click on the java class > Run As > Java Application. Let us try to execute our first test case automation script If the script does not find the driver when you run it, it would throw an exception as shown in the image below: Then, the test script looks for the appropriate driver when you initialize the driver to Firefox driver. To run the automation on Firefox, you need to initialize the driver to call Firefox driver. Also, the web and mobile devices both use it. Additionally, it works on multiple operating systems like Windows, macOS, Linux. Mozilla Firefox Browser is a free and open-source web browser. In case you have missed any of the above set up, please refer to the individual tutorials available in our course for them.
Download Gecko driver for Firefox browser.Also, we will learn the following points in this tutorial: In this tutorial, we will learn how we can download the Gecko driver and set the path to execute the Selenium script on Firefox browser using Gecko driver. In short, Gecko Driver is Marionette based solution used for automating Mozilla Firefox. On the other hand, Geckodriver uses Marionette protocol to communicate with the Firefox browser. Also, Selenium sends commands to Geckodriver using W3C protocol, which is a world standard. With Selenium 3, automation script needs to initialize Gecko driver to control Firefox browser. Marionette is the automation driver which uses the remote protocol of Firefox to control the UI. In this tutorial, we are using the latest available version of Firefox with Selenium 3. We do not need Gecko Driver when working on Selenium 2 and old versions of Firefox. Hence, Selenium tests can communicate to it through Gecko driver only.
Also, the latest version of Firefox(version 47.0 onwards) does not allow external drivers to interact with the browser. Therefore, we direct all the Selenium commands to Firefox browser through Gecko Driver. So, we need Gecko Diver to establish the link between Selenium tests and Firefox browser. Why Selenium 3 needs Gecko driverįrom Selenium 3 onwards, there is no native implementation of Firefox. Then, all the tests communicate to this server to run the Selenium commands. Basically, this executable starts a server on the local system. Internally, Selenium tests interact with Firefox using an executable called GeckoDriver.exe. Typically, the applications developed by Mozilla Foundation and the Mozilla Corporation use this driver. Also, GeckoDriver provides a proxy to interact with Gecko-based browsers like Firefox. Introducing GeckoDriver What is Gecko Driver
In this tutorial, we will learn how to execute the Selenium code on the Firefox browser. Hence, to run the Selenium script, on different browsers, we need corresponding browser drivers. But, to achieve this feature Selenium needs browser-specific browser. Selenium is a multi-browser multi-platform automation tool. tProperty(“”,”C://softwares//drivers//geckodriver.exe”).
