German talk at the DATEV Digital Festival about visual regression in Angular by using Storybook together with Cypress and Jest/Puppeteer.
In April this year, even before the release of Angular 12, it became clear what we knew all along. Angular is going to drop Protractor, which has been the official e2e tool since the days of AngularJs.
Although there is no official successor yet and maybe there never will, there is one tool that shines before all others: Cypress.
In this talk, you will get an introduction to Cypress. You will learn how it works, how to use it, and also about its pitfalls. With Cypress, we have finally e2e tests that don’t fail and we can trust.
We all know the problem. A test causes some changes in our database. These changes can break the following tests. Not the nicest thing to do. Unfortunately, we can’t just always mock the database as we can in Unit Tests. So we have to find other ways.
This talk is about various strategies for how to set up our tests so that they have the least possible effect on others.
In this talk, I’ll show how to do visual regression in Angular by combining Storybook with Jest. The talk is in German.
This talk (in German) is about best practices in ngrx. For example, it shows how to implement caching, make use the facade pattern and what to do, if the structure of the state is incompatible with the one of the component.
Why and how you should use OpenAPI to bringt type-safety into the communication between your applications/services.
