This patch is similar to that proposed by Jeremy. The proposed patch altered
the interface of TestResult such that it would be passed the error
information as a string rather than an exc_info() tuple.
The implemented change leaves the interface untouched so that TestResults
are still passed the tracebacks, but stor them in stringified form for
later reporting.
Notes:
- Custom subclasses of TestResult written by users should be unaffected.
- The existing 'unittestgui.py' will still work with this module after the
change.
- Support can later be added to pop into the debugger when an error occurs;
this support should be added to a TestRunner rather than to TestCase itself,
which this change will enable.
(Jeremy, Fred, Guido: Thanks for all the feedback)
If 'unittest.py' was run from the command line with the name of a test
case class as a parameter, it failed with an ugly error. (Which was a
shame, because the documentation says you can do that.)
The problem was the old 'is the class X that you imported from me the same
as my class X?' gotcha.
