Event description
Learn all you need about Unit-Testing Angular with an Angular Google Developer Expert!

About this Event


Unit-testing or more specifically, front-end unit-testing is undeniably in the top 3 of the most complex topics associated with Angular development.

When one is confronted with this complexity, it is tempting to give up, but at what cost? It is totally possible to develop an application without unit-tests but is it really faster? What happens to code maintainability a few months or sometimes just weeks later? Can we serenely refactor and deploy our apps regularly while it is getting older and complex in our hands?

This workshop presents, through practical exercises, pragmatic Angular unit-testing techniques. You will also learn how to implement human-readable, maintainable, and above all profitable tests.


During this workshop, you will learn:

  • how to implement unit tests for your Angular application with the Test-Driven Development approach,
  • choose the type of unit-tests that fits best depending on the context,
  • decouple tests from code to encourage refactoring and tidying up when needed,
  • implement maintainable and human-readable unit-tests,
  • how to implement maintainable and human-readable unit-tests,
  • the difference between fakes, stubs, spies and mocks + how and when to use them,
  • the difference between isolated, shallow & integration component testing,
  • how to choose the right scope for your tests,
  • how and when to use Angular CDK Harnesses,
  • how to test HTTP communication.
