Step 1: Import the component and testing utilities.

Step 2: Render the component using a testing library.

Step 3: Use `expect` to make assertions about the component's output.

Step 4: Simulate user interactions and verify the component's behavior.

Step 1: Mock the API endpoint using a library like `msw`.

Step 2: Make a request to the API endpoint using `fetch` or `axios`.

Step 3: Use `expect` to assert that the response data matches the expected format.

Step 4: Verify that error responses are handled correctly.

Step 1: Render the component and capture its output as a snapshot.

Step 2: Store the snapshot in a file.

Step 3: In subsequent tests, compare the current output to the stored snapshot.

Step 4: If there are differences, review the changes and update the snapshot if necessary.

Step 1: Render the form component.

Step 2: Simulate user input with invalid data.

Step 3: Trigger the form's validation logic.

Step 4: Use `expect` to assert that the appropriate error messages are displayed.

Step 1: Import the modules to be tested.

Step 2: Set up the necessary dependencies and mock any external services.

Step 3: Call the functions or methods that integrate the modules.

Step 4: Use `expect` to assert that the modules interact as expected.
