This can be also related to the following StackOverflow question...

To be more concrete: It's clear how to write tests that validate some expected outputs (testCase.validateEqual() etc.).

However, how do I validate that e.g. some exception was properly thrown as a response to e.g. some bad input data? Usually if an exception occurs in the function-under-test, the corresponding test function is marked as both "failed" and "incomplete".

Use testCase.verifyError. The first input should be a function handle that will throw the error when evaluated, and the second should be the error identifier.
