Understanding Selenium?
Selenium is an open-source automation testing framework. It tests web applications across various browsers and supports browsers like Chrome, Firefox, Safari, and Internet Explorer. It can also simulate user interaction on a website. Selenium automates web browser interaction to test web applications. Testers can use multiple programming languages like C#, Python, Java, etc to create Selenium test scripts. Selenium is often used with other Software testing frameworks.
Selenium is also used to test web applications automatically for performance and functionality. Additionally, Selenium can scrape data from websites or generate reports automatically. In comparison to other testing frameworks, Selenium has a huge advantage. The advantage is that there are no license fees because it is an open-source technology.
Understanding Selenium ChromeDriver
ChromeDriver is a separate executable that Selenium WebDriver uses to control Google Chrome. The Chromium team maintains ChromeDriver with help from WebDriver contributors. WebDriver refers to a collection of APIs. These APIs are used to automate the testing of web applications. Running Selenium test scripts on the Google Chrome browser is impossible without ChromeDriver.
ChromeDriver is a free open-source web driver for automated testing across Google Chrome browsers. Selenium is an umbrella project for many platforms and libraries that enable and support automated web testing. ChromeDriver runs on macOS, Windows, and Linux operating systems.
The main purpose of Selenium ChromeDriver is to launch the browser and perform desired automated operations. The Selenium ChromeDriver comes up with many different capabilities.
What is browser testing?
Browser testing popularly known as cross-browser testing verifies that a website works accurately in all browsers. In another way, it is a quality assurance (QA) process of evaluating whether the functionality of a web application remains consistent when the end-user visits the web application from a different browser.
The main goal is to confirm that the site being developed runs perfectly on all targeted browsers and operating systems to validate browser compatibility. Testers can run manual tests using automated frameworks like Selenium ChromeDriver to save time. Selenium ChromeDriver automates the browser and helps automate web applications across different browsers. After getting a brief idea about browser testing let us know why it is important.
Why is browser testing important?
Browser testing’s contribution to a more positive user experience commits to its importance. There are various versions of desktop browsers and mobile browsers for iOS and Android. Each browser has different levels of support for technologies like cascading style sheets (CSS) or JavaScript programming languages. Browser testing aims to identify defects that can negatively affect how an end user interacts with a page. Browser testing helps developers pinpoint in which browser and its version issues occur.
Steps to download ChromeDriver for Selenium
To run Selenium tests on the Chrome browser, it is important to have a ChromeDriver executable file in the Selenium project. To download the respective ChromeDriver, it is important to check the current version installed in the testing machine. ChromeDriver for Selenium can be downloaded in line with the ChromeDriver version. Mentioned below are the steps to download ChromeDriver for Selenium:
- The first thing to do is navigate to ChromeDriver’s official site for downloading the latest ChromeDriver.
- For the Chrome browser click on “Chrome for Testing availability dashboard”. This will navigate to Chrome for the Testing Dashboard.
- The page has many versions for Dev, Beta, and Canary releases on Mac, Linux, and Windows operating systems. Click on the Stable link and look for ChromeDriver based on the Windows operating system.
- Next, open the URL in the new browser window. ChromeDriver will be downloaded in zip format. Move it to the desired location.
How to configure ChromeDriver?
Configuring Selenium ChromeDriver for browser testing requires several steps. Initially, it is necessary to download the correct version of ChromeDriver. This can be done using the official Selenium website. Testers should ensure the ChromeDriver version aligns with the Chrome browser installed on the tester’s system. ChromeDriver can be configured using different methods. System-level variables on the Windows operating system can be declared using Environment variables. Steps to configure ChromeDriver via the Environment variable are mentioned below:
- Once the ChromeDriver executable is extracted and moved to the desired location, the next step is to copy the location to set its path in the system’s environment.
- Open the environment variable pop-up. This will open the “System Properties” pop-up. Next, click on the “Environment Variables” button.
- Click on the Path variable in the Environment variable pop-up’s System Variables section. Then click on the Edit button.
- The next step is to click the “New” button on the edit environment variable pop-up. Then add the ChromeDriver executable location.
- Click on OK to save the configuration.
Now whenever testers create an instance of ChromeDriver in the Selenium script, it will detect the ChromeDriver path automatically from the system variable. ChromeDriver can even be configured by specifying the ChromeDriver path in the test script.
