Workshops

Pragmatic Angular Testing - Master Class (stationary & online)

Testing or more specifically, front-end testing is undeniably in the top 3 of the most complex topics associated with Angular & front-end 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 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? What about end-to-end tests, they sound attractive but are they enough?

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

What attendees will learn

During this workshop, you will learn:
- how to implement tests for your Angular application with the Test-Driven Development approach,
- how to choose the type of tests that fits best depending on the context,
- how to decouple tests from code to encourage refactoring and tidying up when needed,
- how to implement maintainable and human-readable tests,
- the difference between dummies, stubs, spies, mocks, and fakes + how and when to use them,
- the difference between isolated, shallow & integration component testing,
- how to choose the right scope for your tests,
- lots of tips & tricks that will help you adopt a pragmatic testing strategy.

Course Benefits
You will learn how to write profitable tests, in other terms, you'll learn how to reduce the cost of writing and maintaining tests while increasing their trustworthiness. This will boost the whole team’s confidence and efficiency. You will be able to choose the right tests to implement and how to implement them. You will also learn how to leverage the benefits of Progressive TDD to change your code with confidence, and you will be able to decouple your tests from the tested code so you change the code structure without having to fix tests all the time.
