Type of Functional Testing Techniques
With the advancement of technology, the demand for automated functional testing is increasing. In order to verify and validate the functionalities of an application effectively, there are different types of functional testing techniques. Some of the popular functional testing techniques include:
- Unit Testing
Unit testing is a technique that includes the testing of each and every individual component of the application. It helps in verifying whether the codes developed for the individual components provide the desired results or not. One of the examples of unit testing is that it can be used to test whether an excel application ending with ‘xls’ extension is in the right format.
- Smoke Testing
When the software developers deliver a new build, smoke testing is done to ensure that the basic functionalities are working efficiently. The core aim is to verify the vital functionalities of the application and ensure its optimum working. For example, when an employee application portal is built, smoke testing helps in testing the critical features like login, detail filling, selection of date, and request sent to the manager.
- Regression Testing
While most applications demand modifications to their features or functionalities, there are chances that the changes may give rise to some unusual behavior. Regression testing helps in verifying that the change doesn’t affect the already existing functions of the application.
It helps in the elimination of potential bugs introduced during the modification process. For example, when a leave report feature is added to a leave management system, regression testing is done. It checks that the leave application feature that already existed is not affected by the change.
- Integration Testing
The integration testing technique tests the individual components and tests how they perform together. It also ensures that the modules that work well individually also perform optimally without any flaws when integrated. For example, in an eCommerce site, integration testing is done to test that all the functions work efficiently.
- Sanity Testing
When minor changes are made to new build, sanity testing is a better option as compared to a thorough regression testing. It ensures that the existing bugs are properly fixed, and there is no new issue in the application. For example, in a leave management system, a ‘date selection’ feature undergoes modification. The sanity testing helps in verifying whether the issue has been solved and other features have not been affected.
- User Acceptance Testing
User Acceptance Testing helps in ensuring that the application can successfully handle the essential tasks in real-world situations. It ensures that the software meets the requirements of the users. For example, you have a new application for your business; user acceptance testing can help in ensuring that the application performs well for you as well as your clients.
