funktsionaalsetes

Funktsionaalsetes, also known as functional testing, is a type of software testing that focuses on verifying the correctness of a software application by examining its functions and behaviors. Unlike structural or unit testing, which checks individual components or modules, functional testing evaluates the system as a whole to ensure it meets specified requirements and behaves as intended under various conditions.

The primary goal of functional testing is to identify defects related to the system’s functionality, such as incorrect calculations, improper data processing, or failures in user interactions. Test cases are typically derived from requirements documents, user stories, or other specifications, ensuring that the software adheres to predefined criteria. This approach is widely used across industries, including software development, finance, healthcare, and telecommunications, where reliability and accuracy are critical.

Functional testing can be performed manually or through automated tools, depending on the complexity of the system and the available resources. Manual testing involves human testers executing predefined test cases, while automated testing uses scripts to run repetitive tests efficiently, reducing human error and improving coverage. Common techniques include equivalence partitioning, boundary value analysis, and decision table testing, which help identify potential edge cases and invalid inputs.

Key phases in functional testing include planning, test case design, execution, and reporting. Testers collaborate with developers and stakeholders to define clear objectives, prioritize test scenarios, and track defects. Effective functional testing ensures that software delivers the expected performance, usability, and functionality, ultimately enhancing user satisfaction and system reliability.
