The describe() block in Cypress (inherited from Mocha) is used to group related test cases. It defines a test suite, which helps organize your tests logically and improves readability, structure, and maintainability.
Groups multiple it() (individual test cases) under one common title.
You can nest describe() blocks to further group related tests.
You can add before, after, beforeEach, and afterEach hooks inside a describe() block to manage test setup and teardown.
Group tests by features, pages, or components.
Nest describe() only when needed to maintain clarity.
