Funktsionaalsustestide

Funktsionaalsustestide, also known as functional tests, are a type of software testing that focuses on verifying the functionality of a system or application. Unlike unit tests, which examine individual components, functional tests assess the system as a whole, ensuring that it behaves as expected from a user's perspective. These tests are designed to validate that the software meets its specified requirements and performs the intended functions correctly.

Functional tests can be categorized into several types, including black-box testing, where the tester does not have knowledge of the internal workings of the system, and white-box testing, where the tester has access to the system's code and design. Other types include regression testing, which ensures that new changes do not adversely affect existing functionality, and acceptance testing, which involves end-users to confirm that the system meets their needs and requirements.

The primary goal of functional testing is to identify defects and ensure that the software is reliable, functional, and meets the user's needs. By simulating real-world scenarios, functional tests help identify issues such as incorrect outputs, missing features, and performance bottlenecks. This type of testing is crucial in the software development lifecycle, as it ensures that the final product is robust and meets the specified criteria before it is released to the end-users.
