Setup: — Install Jest and any necessary dependencies (e.g., React Testing Library).

Identify Target: — Determine the component, function, or class to be tested.

Create Test File: — Create a `.test.js` or `.test.ts` file next to the target file or in a `__tests__` directory.

Write Test Cases: — Use `describe` and `it` blocks to organize tests and describe expected behavior.

Implement Mocking: — Mock external dependencies using `jest.mock()` or `jest.spyOn()`.

Run Tests: — Execute the tests using the `jest` command.

Analyze Results: — Review test results and debug any failures.

Refactor: — Improve test coverage and code quality based on test results.
