failureException

This class attribute gives the exception raised by the test method. If a test framework needs to use a specialized exception, possibly to carry additional information, it must subclass this exception in order to “play fair” with the framework. The initial value of this attribute is AssertionError.

Hi,

what do you think about the idea to add an optional data kwarg to unittest.failureExeption()?

Up to now a the exception class "failureException" does only get a message which is a string.

I would like to log the failed Exceptions to a structured logging back end.

Parsing the string message to extract the real value is possible, but somehow ugly and error prone.

My high level use case: Have a system (maybe ELK-Stack) to investigate if a test failure was seen before.

Doing this on strings could work, but I would like to keep the original (json serializable) values.

What do you think?
