Functional Testing with Selenium

Functional testing is a sort of testing that aims to determine whether each application feature functions in accordance with the needs of the software. To determine whether a function’s output is in line with the expectations of the end user, each function is compared to the associated requirement.

What is Functional Testing?

Are we building the product right?

Functionality Testing is exactly what it sounds like. Functional testing is possible at all system levels, from unit testing to acceptance testing.

It is possible to simulate this by recording and playing it back or by using one of the many compatible languages that are listed in this blog.

Types of Functional Testing

There are three primary Types of Functional Testing at the system and UI levels:

1. Smoke Testing: Smoke testing is a quick way to make sure your built is Functioning Correctly. Every time you build your code, you should at the very least perform a smoke test, even if no changes were made. Instead of extensively testing everything, this usually entails going through the key user processes.

2. Regression Testing: Verifying that the product still Works As Intended after Recent Changes is the goal of regression testing. This is crucial if you’ve changed the functionality or introduced any new code. Additionally, if you have performed any problem fixes—and bug patches have a nasty way of affecting other bits of code—it is necessary. This is a significantly more time-consuming method that must test each moving component of your software.

3. Integration Testing: Testing Newly Integrated system capabilities is known as integration testing. If the additional functionality has a significant impact, this can occasionally be difficult. Integration testing should be Conducted for both new UI Features and Backend and core functionality.

Selenium is a Web Testing Tool that employs straightforward scripts to conduct tests from inside of a browser. It “Automates Browsers,” to put it simply. It also offers a record/playback tool for creating tests without having to learn a test scripting language. It is a portable software testing framework for web applications (Selenium IDE).

Automated Functional Testing Using Selenium

Selenium is made up of Four Independent Tools: Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid. Selenium is not a single application to test your web app’s functionality, you can use any of the tools available. Additionally, Selenium provides a client-server architecture with both client and server elements.

Now, use Selenium to Automate Functional Testing by performing the actions listed below:

Selenium is the Greatest Solution for automating web app testing because it is Free to Use and Open Source. To test the functionality of your web app, however, if you’re new to automation testing and aren’t familiar with Selenium Grid, you may utilize LambdaTest, which is already linked with Selenium Grid.

In functional testing, what is tested?

Functional testing’s main goal is to examine the Software System’s Functionality. It focuses primarily on –

Primary Functions: Examining an application’s primary features

Basic Usability: The system will be put through some basic usability testing. It determines whether a user can freely and easily browse through the screens.

Accessibility: Verifies the system’s usability for the user.

Popular Functional Testing Tools are listed below:

• Selenium: Popular Open-Source Functional Testing Tool
• QTP: HP’s QTP is an extremely user-friendly functional test tool.
• JUnit: It is mostly used with Java programmes and is useful for unit and system testing.
• soap UI: It is a functional testing tool that is open source and primarily used for Web service testing. Numerous protocols, including HTTP, SOAP, and JDBC, are supported.
• Watir: It is a tool for web application functional testing. It employs the ruby scripting language and supports web browser tests.

Conclusion: Functional testing in software testing is the process of evaluating a system’s capabilities to make sure they function as defined in the business document. This testing’s objective is to determine whether the system is flawless in terms of functionality, and this can easily be achieved using selenium.

Happy coding!
