Testing and debugging are crucial steps in the development process to ensure that software functions correctly and efficiently. Writing tests involves creating specific scenarios to check if various parts of the software perform as expected. These tests can be unit tests, which focus on individual components, or integration tests, which evaluate how different parts of the software work together. Running these tests helps identify issues or bugs by comparing the actual behavior of the software with the expected outcomes. Debugging follows testing and is the process of investigating and fixing any problems uncovered during testing. It often involves examining code, checking for errors, and ensuring that all parts of the software interact correctly. By thoroughly testing and debugging, developers can improve the software’s reliability and performance, ultimately leading to a more robust final product.
