### Overview of Functional Testing

The purpose of [functional testing](https://www.lambdatest.com/learning-hub/functional-testing/?utm_source=devto&utm_medium=organic&utm_campaign=45090&utm_term=ap&utm_content=learning_hub) is to verify that a product fulfills functional requirements or behaves acceptably. For example, when clicking on a search bar in a search engine, a user should see a list of top searches in the results. This feature helps users find the information they are looking for more quickly, and it can also help them discover new topics of interest.

Developers and functional testers are technical professionals who validate software against functional specifications. They interpret the requirements based on their knowledge and use it to develop and test the software. Domain knowledge is essential as it helps testers better understand the specific needs and expectations of the system’s users.

To carry out effective functional testing, it is crucial to use a combination of both testing based on needs and testing based on business scenarios. Testing based on requirements ensures that all the necessary features and functions are implemented. In contrast, testing based on business scenarios ensures the system works as intended from a user’s perspective.

### Why Need Functional Testing Tools?

Can you imagine manually testing all of the features and functions of an extensive, complex software application? It would be time-consuming, tedious, and prone to human error. That’s where functional testing tools come in –

* As testing teams increasingly push a fail-fast, fix-fast approach, automating functional tests is essential to ensure internal processes are strictly followed, resulting in more accurate test results. Automated functional tests can be run 24/7 without human intervention, making it significantly faster than manual testing.
    
* When analyzing [test reports](https://www.lambdatest.com/learning-hub/test-reports?utm_source=devto&utm_medium=organic&utm_campaign=45090&utm_term=ap&utm_content=learning_hub), it is crucial to prioritize the analysis of defects as they are the most significant failures to investigate.
    
* Organizations that lack coordinated reporting methods may spend excessive time and resources on backlogs. Defects detected earlier also cost less than defects discovered manually at the end of the development process.
    

An example scenario is entering the correct login credentials on an application, navigating to the homepage, performing various actions, and logging out of the system error-free. A fully privileged user could make account changes, while another user with limited privileges would have restricted access to certain features and functionalities.

With automated tools, you can modify [test data](https://www.lambdatest.com/learning-hub/test-data?utm_source=devto&utm_medium=organic&utm_campaign=45090&utm_term=ap&utm_content=learning_hub) for easy customization, enabling teams to efficiently run sequential tests with slightly different data to compare results.

Functional testing tools offer other core capabilities, which we will discuss in the next section.
