What is Test-Driven Development (TDD) primarily focused on?
- Code optimization
- Ensuring code quality through testing
- User interface design
- Writing tests after code implementation
Test-Driven Development (TDD) is primarily focused on ensuring code quality through testing. In TDD, tests are written before the actual code implementation, and the development process revolves around making these tests pass. This approach helps catch bugs early and ensures that the code meets the specified requirements.
A client wants their website to be accessible on all devices without compromising user experience. How would you approach this requirement in your responsive design?
