During running test case, when test case failed with exception error raising by the python lib, the robot seems terminated by itself.

Here is the partial error message shown in console log:

redfish.rest.v1.RetriesExhaustedError

Try --help for usage information.

This error indicate that the redfish python lib encounter some network issue, it retries many times and raise exception.

I also try to regenerate report.html by execute rebot output.xml, but it says:

[ ERROR ] Reading XML source 'output.xml' failed: Incompatible child element 'errors' for 'suite'.

Try --help for usage information.

Here is the output.xml:

For some reason the whole execution crashes when initializing the library as part of the importing process fails. This shouldn't happen, we have tests for handling errors like this so that execution can continue normally. I also tested this separately with a simple library that has a failing __init__. I even tried raising redfish.rest.v1.RetriesExhaustedError to see is that exception somehow special, but also that was handled fine.

Can you provide a simple example I could use to reproduce this? Also, what Robot Framework version did you use?

Any new info related to this? I cannot reproduce the problem so if there's no updates I cannot do anything else than close this issue.
