You should be testing your app, but, in reality, it is hard and cumbersome to keep all your tests up to date and develop the tests using TDD methodology. Choosing the proper tools for the job is the first step to achieve this goal. In this session, Michal Szcepani will compare testing performance using both Jest and Jasmine within an Angular application, analyze how the watchers work in both frameworks, share some migration strategies to convert the existing Jasmine infrastructure to Jest, and explore snapshot testing.
