[arcuri82]

@aruvic thanks for reporting this bug. For now, can you try to run with --doCollectImpact false --probOfArchiveMutation 0 to disable that part of the code?

@man-zhang do you think you have some time to look into this issue?

[aruvic]

Thanks, it worked now. Please can you just check if the current behaviour is as expected.

Driver was run as following. Can I safely ignore the warnings?

After Driver was running EvoMaster with the additional flags was working. Please can you check if the output of the run is as expected? * Needed budget: 26%, Does this mean I can run this in 26% of 10 minutes and it will achieve same results?
Is * Bytecode line coverage: 3% also expected or this is very low?

hi @aruvic ,

regarding your questions:

1. Can I safely ignore the warnings? -> yes

2. Needed budget: 26%, Does this mean I can run this in 26% of 10 minutes and it will achieve same results? -> not exactly (it is a complex story...), but yes, at the high level that is the idea. Can be used as a rough estimate of for how long to run future runs on same API

3. Bytecode line coverage: 3% also expected or this is very low? -> indeed, it is extremely low. in your logs you had a lot of warnings like No fields for object definition: partyOrPartyRole. wondering if those objects are constructed with some OpenAPI syntax we do not handle (which could explain those results). Could it be possible to paste here one of such definitions?

4. Can this missing Kafka Client dependency be safely ignored? -> yes, ignore those. we should actually avoid printing such confusing stack-traces, as it is not an error, but actually something that could be expected to happen in practice

hi @aruvic ,

we have added some more logs to help debugging this issue regarding mismatched gene impact. could you please re-run it and paste here the updated stacktrace info? many thanks!
