How do you test code that uses exception chaining?

Testing code that utilizes exception chaining can be crucial for ensuring that your application handles errors effectively. Exception chaining allows an exception to encapsulate another exception, preserving the original error information. When you test such code, you'll want to verify that both the primary and the chained exceptions are handled correctly.

To test code with exception chaining, you can follow these steps:

1. Trigger the main exception.
2. Catch the exception and verify that it contains the expected message or type.
3. Verify the underlying cause of the exception to ensure the chaining works as intended.
