The purpose of functional testing is to ensure that the system under test's features are functioning as intended and meeting all of its requirements. Rather than focusing on the inner workings of the code or the finer points of implementation, functional testing aims to guarantee that the software can carry out its intended tasks. Among the many varieties of software testing, functional testing is among the most fundamental and widely used. From testing individual components to checking for feature regressions, functional testing covers it all. Some types of functional testing are presented here. You can contact a professional like Flexsin, which is a web development company that provides software testing services. Now, let’s understand the different types of functional testing in detail.

Unit Testing: Developers execute these checks by writing scripts that check if certain application units or components meet the specifications. It is a common practice to write tests that invoke the methods in each unit and verify their validity when they return results that meet the specifications.

Integration Testing: The goal of integration testing is to determine the reliability of combining several software components to achieve the expected performance. Even if a module has already passed its tests, it still has to undergo this form of testing to guarantee that it will function as intended when reliant on other modules.

Smoke Testing: Smoke testing is conducted to ensure that the most important features of the application function as expected. This is merely the start of the testing process and does not aim to encompass all potential scenarios. Smoke tests guarantee the application's fundamental functionality.

Regression Testing: There is a high probability that upgrades can induce unanticipated behaviors if developers alter or adjust the functionality or feature. If you want to be sure that your update didn't disrupt any of the previously implemented features, you should run regression tests. Its goal is to detect any newly introduced bugs in the current build and keep any bugs that have been eliminated from it from returning. When it comes to regression testing, there are many functional testing tools to choose from.

Sanity Testing: The purpose of sanity testing is the same as that of regression testing: to ensure that any newly introduced code or builds with small bug fixes pass muster. If the build fails the sanity test, it will not go on to the next stage of testing. Regression testing checks the entire system after modifications, while sanity testing focuses on the parts of the system directly impacted by the code changes.
