When using Jest, what does the term "mocking" refer to?

  • Creating fake modules to replace real ones.
  • Writing assertive test cases.
  • Generating random test data.
  • Testing asynchronous code.
In Jest, the term "mocking" refers to creating fake modules or functions to replace real ones during testing. This allows you to control the behavior of dependencies and isolate the code being tested. Mocking is commonly used to ensure that a function or module behaves as expected and to avoid making actual network requests or database calls. The other options describe different aspects of testing but do not directly relate to the concept of mocking in Jest.
