I am trying to generate the dynamic slice for the junit assertions in a test class of the joda-time subject. However, the script throws error such as:

looking for LINENO:324:FILE:org.joda.time.tz.TestBuilder None Traceback (most recent call last): File "run_benchmarks.py", line 207, in run_slicer4j(project, jar_name, project_arg, extra_libs, sc_file, slice_line) File "run_benchmarks.py", line 148, in run_slicer4j line = sc.split(", ")[0] AttributeError: 'NoneType' object has no attribute 'split'

Is it because the tool does not instrument test classes? Not sure if I am making any mistake, any help would be highly appreciated!

At the moment, Slicer4J requires all classes to be in the packaged jar. So you can only slice from either the main classes, or modify the build system to include the test classes into the jar to be sliced.
