Re: [Wavepacket-ng-devel] task #4 - evaluating some unit testing and mocking frameworks

[Piotr B. <dms...@gm...>]

Following the suggestion i will try to describe some relevant features of
the CxxTest framework:

1. Minimal amount of work needed to add new tests

Creating new test cases with CxxTest turns out pretty easy and requires
minimal programming effort.
No manual registration of test cases or use of some ugly macros is needed.
CxxTest gets around that by parsing test cases and generating a C++ test
runner.
The build process looks like the following:
1. Tests are defined in C++ header files
2. The "cxxtestgen" command line tool processes header files to generate
files for the test runner.
3. Finally, the test runner can be compiled and executed to run all test
suites.

3. Supports fixtures.

Great support. A wide range of functions available:
- setup/teardown for individual tests
- setup/teardown for the whole test suite
- world(global) fixtures

4. Handles exceptions and crashes well

Very good. Again, a rich set of functions is available to check if certain
exceptions were thrown.
No support for dealing with C++ signals found yet.
I have not found on this topic in the documentation or during google search.
Maybe we'll find more info in CxxTest forum. I have already asked for some
hint - https://groups.google.com/forum/?hl=en#!forum/cxxtest-forum

5. Supports different outputs

Good support. In addition to the standard output, the test results can be
stored in XML format.

Another plus - CxxTest supports testing with mock objects which i will
study in next step.
Last but not least i have attached an example test suite to the Ticket.
