Funktsioonitestimise

Funktsioonitestimine, also known as functional testing, is a type of software testing that focuses on verifying that the software functions as intended according to the specified requirements. It is one of the most common types of testing and is typically performed after unit testing and before system testing. The primary goal of functional testing is to ensure that the software meets the functional requirements and behaves as expected under various conditions.

Functional testing can be categorized into several types, including:

1. Black-box testing: This type of testing is performed without knowledge of the internal workings of the software. Testers focus on the inputs and expected outputs, ensuring that the software behaves correctly from the user's perspective.

2. White-box testing: Also known as clear-box testing, this approach involves testing the internal structure or workings of the software. Testers have knowledge of the internal code and design, allowing them to create tests that cover all possible paths and conditions within the software.

3. Grey-box testing: This approach combines elements of both black-box and white-box testing. Testers have partial knowledge of the internal workings of the software and use this information to create more effective tests.

Functional testing is typically performed using a variety of techniques, such as equivalence partitioning, boundary value analysis, and decision table testing. These techniques help testers create a comprehensive set of test cases that cover all possible inputs and conditions.

Overall, functional testing is a critical component of the software testing process, helping to ensure that the software meets the specified requirements and behaves as expected under various conditions. By identifying and addressing functional defects early in the development process, functional testing helps to improve the quality and reliability of the software.
