I did develop some small python library called "DTest" which helps for that kind of thing. see: http://download.savannah.gnu.org/releases/tsp/dtest/what_is_dtest.pdf. I'm using it with CMake/CTest to test distributed applications (HLA distributed simulation) see eg: http://www.nongnu.org/certi/certi_doc/User/html/execute.html The idea is to build all needed executables with CMake, then use CTest to launch a python script which may open as many ssh connection as needed on specified machine and run the executable. This looks like the same idea as the Paraview "driver" but I think it could be of general use. CTest then tests the return status of the scripts. Example of such a script: http://cvs.savannah.gnu.org/viewvc/applications/HLA_Tutorial/dtest_HLA_Tutorial.py?root=certi&view=markup In my current case, each host should have the executable to launch already deployed but you may easily incorporate deployment inside the dtest script since dtest is using an SSH connection thus there are "putFile/getFile" steps which use scp to transfer files. With a dtest script you can easily run several application on the same host too (the usual test case is to ssh on the localhost). I have not much time to enhance DTest currently but I would be glad to share ideas and help people enhancing dtest. The discussion can continue here or on the tsp mailing list: http://lists.nongnu.org/mailman/listinfo/tsp-devel. (dtest is a TSP subproject) I'm not usually doing such "self-promotion" but for this time I do because this kind of question is arising from time to time on this list and may be DTest (or equivalent features) could be a valuable enhancement/or add-on to CTest for some of us. By the way DTest was named after D-istributed Test before I even began to use CTest :-) So there is no DMake nor DPack :-) -- Erk Membre de l'April - « promouvoir et défendre le logiciel libre » - http://www.april.org _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
