What Is TDD?

Test-driven development (TDD) is a software development approach where tests are written before writing the code, ensuring that code meets specified requirements. Agile is a broader development methodology emphasizing iterative development, collaboration, and adaptability. TDD is a practice within Agile methodologies.

Test-driven development (TDD) encourages writing tests before code implementation, ensuring that the code meets specified requirements. This iterative process leads to improved code quality, faster development, and early detection of defects.

Test-driven development (TDD) involves three main steps: write a failing test for a new feature, write the minimum code to pass the test, and refactor the code for better design while keeping all tests passing. This iterative process ensures test coverage and code reliability.

Test-driven development (TDD) focuses on writing tests before code, while behavior-driven development (BDD) emphasizes collaboration between developers, testers, and nontechnical stakeholders to define behavior through examples.

Test-driven development (TDD) is a key practice in DevOps, emphasizing the creation of automated tests before writing code. TDD aligns with DevOps principles by promoting continuous testing and early defect detection.
