Hi, I'm not sure what happens according to the information you provide. But please make sure that fault localization does not fail at the first place. You can try to print the fault localization outputs.

Actually the FL process is redesigned by myself. I directly give the location in the human patch to faultyLines. So there is only one line in this list. I'd like to know if it's possible for number of positive test cases to be 0 under this condition.

This should be possible. It happens when the positive test cases do not visit this faulty line. If you prefer using all test cases, you can set the default value of "testFiltered" to false in
"AbstractRepairProblem. java"

Thanks. But there's one thing I do not figure out. When the number of positive test cases is 0, Arja still prints logs like "One evaluation started" but Genprog and RSRepair do not. Their logs are as I have shown：only end with "Filtering process is end". What causes the difference so?

The possible reason is that the suspiciousness of this faulty line is no larger than a threshold (0.1 default). So the number of modification points is 0. For GenProg and RSRepair, it will lead to an infinite loop due to their initialization procedure. If you really want to just choose one faulty line, you can set the parameter -Dthr to 0.

The default threshold is 0.1 but I manually set the suspiciousness value of each faulty line to be 1. So they all exceed the threshold.

Please check the "mutation" method in GenProgGA.java to see whether the loop is infinite or not.

I find the method but I do not understand it. Does Arja contain this loop? Why Arja can still go on the repair process?

Arja does not contain this loop. The implementation of initialization is different since they are based on different solution representations.

That's ok. So now my modification point number is only one and positive test case number is 0.Would you please explain why the loop is infinite. I don't figure out the relationship between these two things. Thanks so much

If the number of modification points is not 0, I think the loop should not be infinite.
The repair should go on.
Please find the doMutation method in GenProgMutation.java and add a line of code
before the for loop to make sure that edits.getNumberOfLocations() is not 0.
