Re: [easyb-users] Verifying attributes of exceptions

[Andrew Glover]

You could put the code under test in a try/catch block and in the catch, assert various aspects of the caught exception. ex.getMessage().should etc...

I am a new user to easyb and was wondering if anybody can provide some guidance on how to verify the attributes of a thrown exception.

I can check that the exception is thrown using ensureThrows but how do I check that the message of the exception i.e. ex.getMessage() contains some specific text?

My then clause looks as follows:

    then "Exception should be thrown with details of invalid subject", 

    {

        ensureThrows(Exception)

        {

            factory.create(aCalculatedGroup)

        }

    }

Thanks,

David

I'd add that I wonder what's actually being tested.

This sounds more like a case for an exception class that takes the information as ctor/builder arguments and constructs the message from that data.

Rather than testing behavior by parsing out a string, test the exception on its own, and test the class you're talking about here by making sure it throws an exception of the appropriate type.

I might be misinterpreting, though.
