Summary

In this chapter, we embarked on creating a weather application from scratch, adhering to the TDD methodology. We employed Cypress for user acceptance tests and Jest for unit tests, progressively building out the application’s features. Key practices such as modeling domain objects, stubbing network requests, and applying the single responsibility principle during refactoring were also explored.

While not exhaustive in covering all the techniques from previous chapters, this chapter underscored the importance of maintaining a disciplined pace during the development phase. It highlighted the value of being able to identify code “smells” and address them effectively, all while ensuring a solid test coverage to foster a robust and maintainable codebase. This chapter served as a practical synthesis, urging you to apply the acquired knowledge and techniques to enhance the application further.

In the upcoming and concluding chapter, we’ll recap the...
