What is Cypress Hooks

 Cypress Hooks refer to a set of functions provided by the Cypress testing framework that enable users to interact with and control the testing environment. Introduced in Cypress version 6.0, Hooks enhance the flexibility and extensibility of Cypress test scripts by allowing users to run custom code at various points during the test lifecycle.

The primary Hooks in Cypress include before, beforeEach, after, and afterEach. These Hooks enable users to execute setup and teardown tasks before or after test suites or individual test cases. For instance, the beforeEach Hook can be used to set up the necessary test conditions, such as visiting a webpage or logging in, before each test case runs. Conversely, the afterEach Hook is useful for cleaning up resources or resetting the state after each test.  - Cypress Training

Cypress Hooks can be defined in the test files or in the configuration file (cypress.json). When defined in the configuration file, Hooks apply globally to all test files, providing a centralized way to manage setup and teardown tasks across the entire test suite.  - Cypress Training in Hyderabad

 Here's a brief overview of each Cypress Hook:

before:

This Hook runs once before all test cases in a test suite. It is typically used for global setup tasks that need to be performed only once. - Cypress Online Training

beforeEach:

Executed before each test case within a test suite. Useful for setting up a consistent state before each test, such as navigating to a specific page.

afterEach:

Runs after each test case. It is commonly used for cleaning up resources or resetting the state to ensure test independence.  - Cypress Online Training Course

 after:

This Hook is executed once after all test cases in a test suite have completed. It is suitable for global teardown tasks. - Cypress Training Institutes in Hyderabad

 Cypress Hooks are powerful tools for customizing the test execution flow and handling various scenarios. They contribute to the maintainability and scalability of Cypress test suites by allowing users to encapsulate common setup and teardown logic. By leveraging Hooks effectively, developers can create more robust and modular Cypress tests, ultimately enhancing the reliability of their web applications.
