Feketetest

Feketetest, also known as *black test* or *black box testing*, is a software testing technique used to evaluate a system without prior knowledge of its internal workings. The term originates from the practice of treating the system as a "black box," where inputs are provided, and outputs are observed without examining the internal logic or code. This method is widely applied in software development to ensure functionality, reliability, and usability from the end-user perspective.

The primary goal of feketetest is to identify defects, validate requirements, and assess compliance with specified behaviors. Testers use predefined test cases or scenarios, often based on user stories or functional specifications, to verify that the system behaves as expected. Unlike white-box testing, which examines internal structures, feketetest focuses solely on the system’s external interface, such as user interfaces, APIs, or command-line inputs.

This approach is particularly useful in regression testing, where changes to the codebase may introduce unintended side effects. It is also common in acceptance testing, where stakeholders verify that the system meets business requirements before deployment. Feketetest can be automated or performed manually, depending on the testing phase and objectives.

While effective for uncovering functional issues, feketetest does not reveal structural problems like performance bottlenecks or security vulnerabilities, which may require additional testing methods. It is often complemented by other techniques, such as integration testing or stress testing, to provide a comprehensive evaluation of the system’s quality.
