What are the benefits of Test-Driven Development?

Test-Driven Development (TDD) offers several benefits, including improved code quality, easier debugging, and better design. It encourages developers to think through their code before writing it, leading to fewer bugs and more maintainable code.

Can you explain how TDD improves code quality?

TDD improves code quality by ensuring that tests are written before the code itself. This means that the code is constantly being validated against the tests, which helps catch errors early and encourages writing only the necessary code to pass the tests.

What challenges might developers face when implementing TDD?

Some challenges include the initial time investment to write tests, the learning curve for new developers, and the potential for over-testing, which can slow down development.

Is TDD suitable for all types of projects?

While TDD can be beneficial for many projects, it may not be suitable for all. Projects with rapidly changing requirements or very small codebases might find it less effective.
