This seminar, we will discuss a way of writing unit tests and approaches to Test Driven Development.

TDD approach: Red-Green-Refactor

Red: Write a test and see it fails.

Green: Write a code, check whether the test passes.

Refactor: rewrite the code to be short, understandable and more effective, use design patterns and SOLID principles. Run the tests often and keep then green.

TDD events

If you want to make you TDD skills better, there are Code Retreat events where you can practice programming, object-oriented design and TDD.
