Several testing methodologies are used in software testing, such as:

1. Manual Testing: Testers manually execute test cases without using any automation tools.
2. Automated Testing: Testing performed using automation tools to speed up the testing process and enhance accuracy.
3. Black Box Testing: Testing where the internal logic of the software is not known; the focus is on inputs and expected outputs.
4. White Box Testing: Testing where the internal logic and code of the software are known and tested accordingly.
5. Regression Testing: Repeatedly testing software after changes to ensure that new modifications do not adversely affect existing functionalities.

In the realm of software testing, a variety of methodologies are employed to ensure the robustness and reliability of applications. If you're aiming to dive into this field, consider augmenting your skills through relevant courses, such as a Python programming course in Meerut, which can significantly enhance your testing capabilities.
