Test Driven Development (TDD) Training in Astana, Kazakhstan

Test-Driven Development (TDD) training teaches participants how to adopt a test-first approach to software development, where tests are written before the actual code. The course covers the core principles of TDD, including writing failing tests, implementing code to pass the tests, and refactoring for cleaner design. Participants learn how to use testing frameworks, such as JUnit, NUnit, or pytest, to write unit tests that drive the development process. Hands-on exercises focus on writing effective test cases, maintaining a fast feedback loop, and ensuring code quality through continuous testing. By the end of the training, attendees are equipped to apply TDD practices in their own development workflow, resulting in more reliable and maintainable software.

Introduction to TDD and the Red-Green-Refactor Cycle

• Introduction to Test-Driven Development (TDD)

• What is TDD and why is it important?

• The benefits of TDD: improved software design, cleaner code, fewer bugs, faster development.

• TDD in the context of Agile software development.

• TDD vs. traditional testing approaches.

• The Red-Green-Refactor Cycle

• Introduction to the Red-Green-Refactor cycle:

• Red: Write a failing test.

• Green: Write just enough code to pass the test.

• Refactor: Improve the code without changing its behavior.

• Hands-On Exercise

• Writing the First Test

• How to write effective and meaningful unit tests.

• Choosing which behavior to test and how to create effective assertions.

• Hands-On Exercise

• Writing the minimal code to make the test pass.

• Importance of simplicity and focusing on the immediate goal.

• Hands-On Exercise

• Refactoring the Code

• What is refactoring and why is it essential in TDD?
