The document discusses Test-Driven Development (TDD), which is a software development process that emphasizes short development cycles and the need for testing code. It highlights the advantages of well-tested software, including reduced costs, low maintenance, and fewer bugs. The TDD cycle is outlined as a repetitive process involving adding tests, running tests, writing code, and refactoring.

4. 1. What is TDD
• Test Driven Development (TDD)
• Is a software development process
• Relies on the repetition of a very short development
cycle

6. 2. Why do we need to test
our code?
• Well-tested software
• Bug free software
• Low maintenance code
• Less costs

9. We do not want to deliver
untested software

10. Test first

11. Well tested software: durable, without
extra costs, easy to maintain and bug free

13. 1. Test-driven development
cycle
• Add a Test
• Run all the tests and see if the new test fails
• Write the code
• Run tests
• Refractor
• Repeat
