The mars test cases are now located in .../test_suite/mars. The use case .../test_suite/example describes how the frame work works (please refer to README). mars_test_cronjob.sh have a second parameter which specifies the use case directory (.../test_suite/mars). The leading numbers in the module numbers are no longer needed.
