Several questions about the test cases files

KeyError: 'PathTestCases'

I got this error when running CLI.py.

[Q1] Are the test case files necessary when running CLI.py? I do not see relative arguments in "usage".

usage: run.py [-h] --targetContractName TARGETCONTRACTNAME [--timeout TIMEOUT]
              [--json] [--detectorArg KEY=VALUE] [--targetVul vulnerability]
              [--targetLoc CodeRange object in JSON format]
              [--synthesizerArg KEY=VALUE] [--core CORE] [--coreArg KEY=VALUE]
              {repair} ... source_file

[Q2] If the test case files are necessary, could you please provide some test case files examples and the arguments should be filled in "usage"?
