Look inside

In this liveProject, you’ll reduce a test’s coupling to the implementation (thereby reducing the tests’s dependence on the details of how the code works) and extend a feature using test-driven development for an e-commerce record store. You’ll begin by applying techniques to increase test readability, then implement a full stack feature that requires changes to all layers of the system. Lastly, you’ll tidy up by refactoring the implementation to reduce conceptional duplication, making the code easier to read and maintain.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

  • Basic Spring MVC
  • Basic JUnit
  • Basic JavaScript
  • Basic HTML
  • Basic React
  • Basic SQL
  • Basic Unit Testing

This liveProject will prime you on the basics of test-driven development, and using it to drive bug-free development of new features.

  • The attributes of a well formed unit test
  • White-box and black-box testing, and how to choose between them
  • Refactoring an end-to-end test to be less coupled to the implementation
  • Using TDD to implement a full stack feature
  • Refactoring for improved readability, and reduced conceptional duplication
