Since LLDB's python code is not organized into a standard python package and we treat the scripts like dotest etc as standalone scripts, the way I've made this work is by introducing a module called lldb_shared under test which, when you import it, fixes up sys.path to correctly add all the right locations under lldb/third_party.<br>
