If you are building a consumer-centric web application or website, your specific product is likely to be accessed by consumers worldwide. Your SaaS product should be tested on several combinations of devices, web browsers, and platforms (operating systems) to make certain top-notch performance. No one wants to lose potential users because of unpleasant user experiences. Therefore, compatibility testing becomes even more critical. The most productive and economical way to do this is by implementing cloud-centric automated browser testing, or Selenium tests, to be precise. Wondering why it is the most effective way? Allow me to dive deep into the importance of using Selenium Webdriver 4 for the compatibility tests of SaaS products.
Developers who have practical experience with Selenium can’t deny talking about the crucial rewards of using Selenium for browser compatibility testing. Selenium is one of the most popular open-source test frameworks that is used to automate the activities of the product under test. It counts around 27.55% of the overall market share of software testing tools to date. However, Selenium is not just a sole tool, it is a suite of automation tools, every single component appealing to a business’s multiple testing needs.
There are three components or categories of Selenium Suite:
- Selenium Grid
- Selenium IDE (which is now deprecated)
Most of the time, when people discuss Selenium, they actually mean Selenium WebDriver. Developed by Simon Stewart in the year 2006, Selenium WebDriver was the first prime cross-platform tests framework that could control and configure the browsers on the Operating System level. It served as a programming interface to generate and execute test cases. Unlike Selenium Remote Control, WebDriver doesn’t necessitate a core engine such as RC & interacts natively with the web browser apps. WebDriver also supports multiple programming languages like Ruby, Python, Perl, and PHP. It can also be incorporated with frameworks such as JUnit and TestNG for Selenium automated testing management.
Selenium WebDriver is the core element of the Selenium framework, as it allows the interfacing of the test code with the components of the web page under testing. It connects straight with a web browser & has a browser-specific application. Conversely, Selenium Integrated Development Environment or Selenium IDE is a plugin that lets you record test scripts and playback the current ones.
Which Browsers can I run Selenium Testing on?
Most mobile/ desktop browsers today have built-in support for test automation with automated tools like Selenium. Consumer browser vendors like Safari, Chrome, Firefox, Opera and IE develop and ship their browser drivers. In the past decade, when it was first open-sourced, others have contributed to the Se (Selenium) project by accumulating 3rd party drivers for specialized browsers like HtmlUnit and BlackBerry 10, as well as bindings for incorporation with development frameworks such as Qt, PhantomJS, etc.

Selenium WebDriver: Installation and set up
In this segment, we look at setting up Selenium WebDriver for the Windows OS with Java as the core programming language. For the demo, I used the Eclipse IDE. But, you can select to use the IDE of your choice.
Begin with the Prerequisites:
- Firstly Install Java
- Then, Install Eclipse IDE
- Later, Install Selenium WebDriver
Step 1: Visit the authorized Java Downloads site & for Windows x64 Installer and downloads the JDK.
Step 2: You should accept the license agreement in the pop-up and, press tick & click on Download.
Step 3: Once the download is finished, navigate to the Downloads folder & then double-click the executable so that Java is properly installed in the system.
Set Up Environment Variables
Step 1: Open your computer settings and choose from the System dialog window. ‘Advanced system settings’.
Step 2: Click on the button named Environment Variables in the next window.
Step 3: Then, under the System variables, you need to double-click on Path.
Step 4: Add the entire path of the Java installation directory consistent with your system location & click OK.
Step 5: You can now check the top path in the screenshot is the Java route in the system.
To validate whether the Java is installed properly & variables are set properly, you need to click on Command Prompt & type: java -version. You will find that the Java version is installed properly in your system.
And now all set; your first prerequisite is done. The next step is installing Eclipse.
Step 1: Now, download Eclipse IDE (for Java Developers) from the authorized Eclipse website. It would be better to download the latest stable release. Choose the download based on the specific system architecture. You can use eclipse Mars, but you can pick any of the latest versions.
Step 2: Once the download is finished, at your convenience, extract the zip file at a location.
The Eclipse will open, and there you are done with your 2nd prerequisite of this Se (Selenium) WebDriver.
Install Selenium WebDriver
The last phase in this Selenium WebDriver is to install the Selenium Standalone Server:
Step 1: Try to Download Selenium Client and WebDriver Language Bindings from the authorized Se (Selenium) website. You can download the client libraries in consent with your language preference.
Step 2: Once you are done with the file download, extract it to a folder of your selection from where you can use it later.
Step 3: You can now check the corresponding extracted file at the particular destination folder.
Step 4: When you open the folder, you can notice the jar files, a libs folder (which includes a few more jar files), and a CHANGELOG file.
Step 5: Then, you have to download the web browser drivers to assist you in instantiating the browser. Below are the links to download the drivers for a few major browsers:
There is a difference between WebDriver & Remote WebDriver as there is no requirement to download browser drivers when running Selenium testing on a cloud Selenium Grid.
Step 6: Next, just extract the downloaded driver & save it at a location where you can use it.
Now you are done with setting up the prerequisites.
Popular Tools to Create Tests for SaaS Products
These tools are all made or designed for testing on multiple operating systems and browsers in diverse ways.
- Distributed Build via Jenkins
This runs Selenium testing on numerous machines, with Jenkins managing the distributions through its jobs. This is the closest performance to executing local-based testing and can be very effective if set up appropriately.
You can run test scripts faster than any other SaaS-based automated testing grid on LambdaTest’s automated cloud testing platform.
Automation browser testing using cloud Selenium Grid
LambdaTest is a cloud-centric cross-browser testing platform on which you can run the following tasks:
