What are the differences between TDD and other development methodologies?

What are the differences between TDD and other development methodologies?

TDD, or Test-Driven Development, focuses on writing tests before code. Unlike methodologies like Waterfall, which are linear, TDD is iterative and emphasizes continuous testing.

Can you explain how TDD improves code quality?

TDD improves code quality by ensuring that tests are written first, which leads to better design and fewer bugs. It encourages developers to think about edge cases and requirements upfront.

What are some challenges of using TDD?

Some challenges include the initial time investment for writing tests, the need for a shift in mindset, and potential difficulties in testing certain types of code, like UI.

How does TDD compare to Agile methodologies?

TDD can be used within Agile methodologies as a practice to ensure code quality. While Agile focuses on iterative development and collaboration, TDD specifically emphasizes testing.

Is TDD suitable for all types of projects?

TDD is not suitable for every project. It works best in projects with stable requirements and where code quality is a priority, but may be less effective in rapidly changing environments.
