Re: [Cppunit-devel] Subclassing Exception class for better test failure report

[Baptiste L. <bl...@cl...>]

Yes.
If you remember the mail that I wrote a while back, this is the second
option for unicode: having a "string" class in the cppunit nameclass that is
an alias to either std::string or std::wstring. That solution also fit well
with the <sstream>/ostringstream problem.

The method expectionType() would be a victim to that change...

I will rise the unicode problem once the basic will be cleaned up (config,
core stuff working correctly). Should not be so long. I'm nearly done
writing unit tests (there is 72 tests by now and they cover most of the
functionnalities).

Baptiste.

Just a small point - I would like to be able to use CppUnit in Unicode
projects, so I think it needs some generic string class which chances
dependent on using Unicode or not. It could be a simple typedef to
std::string or std::wstring.
