Funktsionaalsustestid

Funktsionaalsustestid, also known as functional testing, is a type of software testing that focuses on the functionality of an application. It is designed to ensure that the software meets the specified requirements and behaves as expected. Functional testing is typically performed after unit testing and before system testing.

The primary goal of functional testing is to verify that each function of the software works as intended. This involves testing individual features, modules, and components to ensure they perform their designated tasks correctly. Functional testing can be further categorized into several types, including:

1. Smoke Testing: This is a preliminary test to ensure that the most critical functions of the software work. It is typically performed to determine if the software is stable enough for further testing.

2. Sanity Testing: Similar to smoke testing, sanity testing is performed to ensure that recent changes or fixes have not adversely affected the software's functionality.

3. Regression Testing: This type of testing is conducted to ensure that new changes or updates have not negatively impacted existing functionality.

4. User Acceptance Testing (UAT): This is the final stage of testing, where the software is tested by end-users to ensure it meets their requirements and is ready for deployment.

Functional testing is crucial for identifying defects, ensuring software quality, and validating that the software meets user needs. It is typically performed using test cases that are designed based on the software's requirements and specifications. The results of functional testing are used to make decisions about whether the software is ready for release or if further development and testing are needed.
