Functional Testing with Selenium Automation Testing

by Syntax Technologies Software Testing Training

The purpose of functional testing is to ascertain whether each application feature complies with the requirements of the software. Each function is compared to the corresponding requirement to ascertain whether its output meets the end user's expectations. This blog would provide you with a comprehensive understanding of what is Selenium Automation Testing, its benefits as well as shortcomings and much more.

Functional testing: What is it?

Testing for functionality is exactly what it sounds like. All system layers, from unit testing to acceptance testing, are capable of functional testing.

Using one of the numerous languages that are listed as compatible in this blog or by recording it and playing it back are two ways to emulate this.


Types of Functional Testing

At the system and UI levels, functional testing is primarily divided into three types:

Smoke Testing: An easy technique to make sure your building is operating properly is to perform a smoke test. Even if no modifications were made, you should at the very least run a smoke test each time you compile your code. This typically involves walking through the most important user processes as opposed to thoroughly evaluating everything.


Regression Testing: The objective of regression testing is to confirm that the product continues to function as intended in the wake of recent changes. If you've updated the functionality or added any new code, this is essential. Furthermore, it is required if you have applied any problem remedies because bug patches have a terrible habit of influencing other pieces of code. This method takes a lot longer and requires testing all of your software's moving parts.


Integration testing is the process of evaluating newly integrated system capabilities. This can occasionally be challenging if the new functionality has a substantial impact. Both new UI features and backend and core functions should undergo integration testing.


What Is Selenium Automation Testing?

Selenium is a web testing tool that uses simple scripts to run tests directly from the browser. Simply said, it "Automates Browsers." Additionally, it provides a record/playback tool so that tests can be created without the need to learn a scripting language. It is a lightweight framework for software testing web applications (Selenium IDE).


Selenium-based automated functional testing

The Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid are the four independent tools that make up Selenium. You can use any of the technologies available, not just Selenium, to test the functioning of your web application. Selenium also offers a client-server architecture that includes both client and server components.

Because it is Open Source and Free to Use, Selenium is the Best Solution for automating web app testing. However, if you're new to automation testing and aren't familiar with Selenium Grid, you can use LambdaTest, which is already connected to Selenium Grid, to test the operation of your web app.


What is tested during functional testing?

The primary objective of functional testing is to evaluate the functionality of the software system. It mostly focuses on -

Examining an application's core features and functions

Basic Usability: A few simple usability tests will be conducted on the system. It decides whether a user can navigate the screens freely and easily.

Accessibility: Confirms that the system is user-friendly.


The following is a list of popular functional testing tools:

Selenium: Popular open-source functional testing tool

QTP: QTP is a very user-friendly functional testing tool from HP.

JUnit: It helps with unit and system testing and is primarily used with Java programmes.

Soap UI: Open source functional testing software called soap UI is mainly used for Web service testing. There are many supported protocols, including HTTP, SOAP, and JDBC.

Watir: It is a tool for functional web application testing, according to Watir. It enables web browser tests and makes use of the Ruby programming language.



The practise of assessing a system's capabilities to ensure that they operate as specified in the business document is known as functional testing in software testing. The goal of this testing is to ascertain whether the system functions flawlessly, and Selenium Automated Testing makes it simple to do so.
