Yes, Test Driven Development (TDD) can be used for both unit testing and integration testing. Unit testing with TDD focuses on testing individual components of the code, ensuring each function or method works correctly. Writing tests first in TDD promotes clean, modular code that's easy to test. Integration testing with TDD checks how different system components work together. By writing tests before integration code, TDD helps identify issues between modules early on, ensuring smooth interaction. Using TDD for both unit and integration testing ensures better code quality, early bug detection, and improved system design.
