This documentation explains how to use 'describe' and 'it' blocks to structure and organize your tests effectively.

Usage of Describe block

  1. Organization - Put together tests that relate to the same functionality or feature within a describe block
  2. Readability - Provide a clear overview of what each group of tests is testing
  3. Setup and Teardown - Use hooks (before, beforeEach, after, afterEach) within a describe block to manage setup and teardown tasks for that group of tests.

It Block

This is a single test case within an overall test file

-It block contains two arguments:

  1. A string containing what the test should do (Description)

  2. An argument which is a callback function that contains the actual test

Usage of It block

  1. Single Responsibility
    Each it block should test a specific behavior or aspect of the
    functionality being tested

  2. Descriptive Names
    Use clear and descriptive names for it blocks to indicate what is
    being tested

  3. Assertions
    Include assertions to verify expected outcomes within each it block
