Hi Maxim, I am not fully following what this patch does -I appologize for this- but I am a bit worried about the usage of scripts and other environment specific usage in the tests. I am trying to restructure the test/validation tree to enventually get one single directory per ODP API module and run all tests using CUnit (as main entry point). The idea being to eventually have a single executable including all tests (but where command line options could select specific tests or suites).
If we go for this approach, all pre and post test setup should be done through the suite initialisation and terminaison functions. I get a bit worried when I see Cunit beeing call by scripts etc... I guess we should maybe have a HO with you Mike Anders and me to try to converge... Christophe.
