my code is fairly well covered with exception handling (try..except). Some exceptions are not expected to happen and some exceptions happen fairly often, which is expected and ok. Now I want to add some automated tests for this code. It would be good to know how many exceptions happened during execution, so I can later see if the expected number was raised or anything unexpected happened. I don’t want to clutter every exception handling block with debug code, so my question is:

Is there a way to install some kind of global exception handler which sits right before all other exception handling blocks? I am searching for a central place to log these exceptions.

Thanks for any suggestions!

(And if this matters: it is Delphi 2009)

    You can do the following:

    • preserve the value of System.RaiseExceptObjProc variable, which in normal Delphi app is pointing to SysUtils.RaiseExceptObject
    • create your own “RaiseExceptObject” proc and assign it to the RaiseExceptObjProc variable
    • in your own “RaiseExceptObject” proc you can do what you want, then call saved RaiseExceptObjProc value

    For details, see above variable and procedure declarations.
