            Bug ID: 431765
           Summary: run_tests.py fail when clazy-standalone traverses a
                    symbolic link
           Product: clazy
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: boboniboni at gmail.com
                CC: smartins at kde.org
  Target Milestone: ---

Clazy-standalone outputs the complete *.cpp file path. Normalizing it so it
compares OK with the expected output by using os.getcwd() (run_tests.py:554)
doesn't work if the source root is traversed via symbolic link path

/insilications/apps/symbolic_link/tests $ ./run_tests.py --verbose
