Exception propagation is the process of passing an exception up the call stack until it is caught and handled. It allows for centralized error handling and prevents exceptions from being accidentally swallowed or ignored.

How to use it in a sentence

• "I'm not sure why the app is crashing, but I suspect it's due to exception propagation from that legacy Perl script we use for currency conversion. Time to break out the debugger and follow the stack trace!"

• "Hey Bob, I noticed you added a bunch of empty catch blocks in your code. You know that's just swallowing the exceptions, right? Let's refactor to use proper exception propagation so we can handle errors at the appropriate level."

• Reporting Database - Fowler discusses separating operational and reporting databases to optimize for different use cases. Proper exception handling is crucial when synchronizing data between these databases.

• Eradicating Non-Determinism in Tests: Resource Leaks - Unhandled exceptions can lead to resource leaks, causing random test failures. Using resource pools in tests can help identify leaks early.

• Continuous Delivery: Synthetic Monitoring - Synthetic monitoring runs automated tests against production regularly. Monitoring exception propagation in these tests can detect issues before they impact users.
