In this 1-hour long project-based course on Introduction to Unit testing In Jest, we will get to explore the anatomy of a Jest unit test, and begin writing code and subsequently, the tests for that code using the Jest framework. By following this course, we will demystify unit tests and understand how we can use them to write better code. we will get practise across the general landscape of the Jest framework to and see how we can use the cool tools provided to us by the awesome Jest developers We will learn all about the syntax of a test, general rules, common matchers, and then start working with testing in asynchronous code and API fetching and then move on to mocking.

  2. Task 2: Start using matchers in our tests to understand how a test works

  3. Task 3: Matchers deep dive #1

  4. Task 4: Matchers deep dive #2

  5. Task 5: Practice writing tests for asynchronous code and API calls

  6. Task 6: Using mocks in our tests

  7. Task 7: Using setup and teardown code in our tests
