Program

What we actually do

  • · Types of tests – how to choose them and what do they mean? Unit tests Component tests Integration tests
  • · To test or not to test?
  • · What does it mean that code is “testable”? Code composition vs. “testability” Implementation details vs. contracts vs. side effects How to handle third-party code in tests Edge cases How to avoid “cementing” implementation
  • · Structure of a good test DRY vs. DAMP vs. WET Boundaries After* and Before* – how to avoid duplication and complications Organization: test suites and test cases Well-chosen assertions Loose vs. tighter assertions Asymmetric matchers Custom matchers Circular assertions
  • · Mocking and test doubles – mocks, stubs, and spies When to use these techniques What to mock Library support Record & Replay pattern Pitfalls of mocking
  • · Integration tests and MSW Where are the boundaries? What are the components we integrate? How to provide data in tests?
  • · Data in tests Fixtures – are they always the right way? How to generate data Snapshots Test data sets (data providers) – write one test for many cases
  • · Testing techniques TDD vs. Code First vs. Test First How to get more from react-testing-library (RTL)? Selectors in RTL – byRole etc. RTL queries – get vs. find vs. query Asynchronous testing with waitFor, act, and find* Testing hooks in RTL Interactions in RTL – user-event Snapshot testing – yay or nay Test Utils – how to extend custom test utilities without creating a mess Custom assertions Jest matchers Utils/Helpers and building abstractions
  • · Code coverage Types of coverage When coverage helps and when it gives a false sense of security
  • · Introduction to e2e tests Introduction to e2e testing Tooling and setup e2e testing challenges
  • · State management and tests What and how to test when using Redux or similar solutions Testing code that uses React Context
Every module is adapted to your stack and context. The above is a starting point — not a fixed agenda.
