What is Black-Box Testing?
Black-box testing is a software testing technique that focuses on assessing the functionality of an application without delving into its internal structures or workings. This approach is particularly advantageous for manual testing, as it allows testers to validate the software's output based purely on specified input, without any need for knowledge of the underlying code.
In black-box testing, the tester interacts with the software through its user interface, providing a series of inputs and evaluating the corresponding outputs. This method is essential for ensuring that the application meets its functional requirements and behaves as expected from the user's perspective. It helps uncover discrepancies between the expected and actual outcomes, including defects and areas for improvement.
Common types of black-box testing include functional testing, system testing, acceptance testing, and regression testing. Each of these focuses on different aspects of the application, ensuring a comprehensive evaluation of its performance under various conditions. By employing black-box testing, organizations can deliver reliable, high-quality software that meets user expectations and industry standards.
