[MaelAudren]

I had the issue with several other test/log/frame.level and I can provide them if they can highlight the issue.

[pderakhshanfar]

The fitness function should be 0. Before that, EvoCrash cannot generate a test for crash replication. As we can see in the output that you sent, the Best individual has fitness: 3.0

[MaelAudren]

@pderakhshanfar Is there a way to play with the parameters in order to generate a correct test ?

[pderakhshanfar]

Since EvoCrash is generating test cases randomly, even without changing configurations we may have some crash replications. The point is that we should apply EvoCrash on more than one stack trace. Because it can be much easier to replicate one stack trace (in some specific target frame) than doing it for another stack trace.
