Agile Testing: TDD & BDD

Testing is integral in Agile, with approaches focused on quality and rapid feedback.

Test Driven Development (TDD)

• Write tests before code implementation.
• Red-Green-Refactor cycle:
  1. Red: Write a failing test.
  2. Green: Write code to pass the test.
  3. Refactor: Improve code without breaking behavior.

Benefits include modularity, reduced debugging time, and higher code quality.

Behavior Driven Development (BDD)

• Write acceptance criteria in plain language (Given-When-Then format).
• Involves both technical and non-technical team members for clear understanding.
• Tools like Cucumber and JUnit automate scenario-based testing in Java.

Collaborative testing ensures requirements are met and builds team confidence.
