🧪Test-driven development (TDD) requires writing tests before writing code.
🚦TDD ensures higher quality software and easier maintenance.
✍️Writing tests first encourages better design and testability.
🗺️TDD focuses on behavior rather than implementation.
⏱️Tests written after code often result in more complex and less thorough testing.
What is test-driven development (TDD)?
—TDD is a software development approach where tests are written before writing the actual code.
Why is writing tests first important in TDD?
—Writing tests first helps ensure higher quality software with better design and testability.
What is the main focus of TDD?
—TDD focuses on the behavior of software rather than its implementation.
What are the benefits of TDD?
—TDD leads to higher quality software, easier maintenance, and faster development.
What are the drawbacks of writing tests after code?
—Tests written after code tend to be more complex and less thorough.
