3. Replicate the Bug: With the development environment set up, the next step is to replicate the bug. Follow the steps outlined in the bug report and observe the behavior of the software. It's essential to be able to consistently reproduce the bug in order to effectively debug and fix it.
White-box testing, also known as clear box testing, glass box testing, or structural testing, is a method where the internal structure, design, and implementation of the software being tested are known to the tester. This approach requires the tester to have an understanding of the code and logic used in the software, allowing them to create test cases that exercise specific paths through the code. The main objective of white-box testing is to ensure that all code paths are tested and that the software functions as intended from a programming perspective.
On the other hand, black-box testing is a method where the internal structure, design, and implementation of the software are not known to the tester. Test cases are created based on the software's specifications and requirements, without any knowledge of the internal code or logic. The main objective of black-box testing is to evaluate the software's functionality and ensure that it meets the specified requirements without needing to understand the internal workings of the software.
The primary difference between white-box and black-box testing lies in the level of knowledge the tester has about the internal workings of the software. White-box testing requires an in-depth understanding of the code, allowing testers to create test cases based on the internal logic and structure of the software. In contrast, black-box testing focuses solely on the external behavior of the software, with test cases being derived from the software's specifications and requirements.
