GeckoDriver acts as a link between your Selenium tests and Firefox, facilitating browser automation. It ’ s needed when using Firefox with Selenium in Python.

This guide explains in detail how to instal GeckoDriver for Selenium Python.

What is GeckoDriver?

GeckoDriver is a web browser locomotive that facilitates communicating between the API and Mozilla Firefox. Using the GeckoDriver protocol, the bidding are interpret into a format that Firefox understands. This allows the automation of browser activeness in Firefox. Since Firefox does not support the legacy driver built into Selenium any longer, using Geckodriver is quite important for running Selenium tests on Firefox.

In short, The browser driver, GeckoDriver, is required to interface between WebDriver-enabled clients and the browser, Firefox, to execute the automation test scripts written in assorted programming languages.

How Does GeckoDriver Work?

To on any browser, a compatible browser driver must be utilized. GeckoDriver let the user to automatise various action on Gecko-based platforms such as Firefox.

Interestingly, GeckoDriver doesn ’ t directly communicate with the Firefox browser, it needs to go through Marionette. Marionette is Firefox ’ s mechanization driver and use Firefox ’ s automation protocol. Essentially Marionette take requests sent to it via GeckoDriver and executes them in Gecko, performing functions such as automated actions on the user interface. GeckoDriver is needed as a go-between for Selenium and Marionette because Marionette protocol isn ’ t compatible with Selenium.

When pass a examination script in Selenium, thegeckodriver.exefile must be used to implement the WebDriver protocol. Compatibility is the main benefit of utilizing GeckoDriver over the built-in Firefox driver. GeckoDriver and Selenium pass utilise the W3C WebDriver protocol. The universally accepted Web Driver standard is W3C. This trait of GeckoDriver is highly beneficial to developer since it make the test more consistent across browsers and stable.

The figure above illustrates how GeckoDriver works.

geckodriver.exe launches a local server that can be used to fulfil test scripts. By act as a proxy, interfacing with Selenium, and translating requests into Marionette mechanization protocol. GeckoDriver establishes communication between Selenium and the Firefox browser.
