The TestRunner.cxx files are all identical and so the Plugin could create a default one and compile it each time the test "target" is invoked. There is an example of this already for the code generation project which has a default server.cpp which is copied onto the disk and compiled when the server target is invoked.
This would be a great feature to add as it gets us closer to being the default cpp plugin for Maven2.
See https://anonsvn.jboss.org/repos/blacktie/atmibroker-xatmi[, tx or core]/src/test/cpp/TestRunner.cxx file for example TestRunner that could be wrapped in the plugin for emitting.
See https://anonsvn.jboss.org/repos/blacktie/codegeneration/src/main/scripts/generate-executables.xml (task server) for how a cpp file is copied from the codeGeneration.jar (and altered at run time, though I don't think we would even need to alter the file initially, maybe if we create an eclipse plugin for it as well?)
