Test Driven Development: Build software with confidence

The course is designed to help understand how to practice Test Driven Development (TDD). It is a software development approach that emphasizes thinking or writing tests before implementing a solution.

The course covers several key techniques like Obvious Implementation, Triangulation and Replace constants with variables to help apply TDD in a systematic approach. Additionally, there are detailed sections about what is Red Green Refactor cycle and how to best utilize these phases to align with business requirements and to improve the code quality. The course also covers why to practice TDD when there are other existing approaches to software development.

It is a short course and focuses primarily on test driven development and not on the very details of testing, like how to write better acceptance tests, integration tests or unit tests. Also the course doesn’t get into deep discussions on testing frameworks or tools as such, for example there will be no discussion on different types of assertions or mocking techniques in testing. It is very important to know that the course focus is on test driven development, but to learn specific testing frameworks in specific languages this course is not the right choice.

In the end, learners will understand that TDD is a mindset that is worth practicing and how to effectively apply it in day to day software development.
