Handling exceptions with unit testing is a software development technique that involves testing how a piece of code handles different types of exceptions that may occur during runtime. Exceptions can be triggered by a variety of factors, such as invalid input, unexpected input, or issues with the environment in which the code is running.

Unit testing is the practice of writing small, automated tests to ensure that individual units of code are working as expected. When it comes to handling exceptions, unit tests can help ensure that the code responds appropriately to various error conditions. As a developer, you need to test that your code can handle exceptions gracefully. You can simulate these error conditions in a controlled environment so that you have more confidence in your code’s ability to handle exceptions that may occur.

For instance, in the case of a Flask application with an attendees endpoint, you may want to test how the application handles...
