Pytests reveal... is is not a method but a property. Are you sure your fix is correct?

[Briimbo]

Yes I am sure it is correct. We use it in our production app and always get a reference to the method in the log, which is identical to what is descibed in the bug report 44022.

Also, if you take a look at the pyexasol implementation of rowcount, you can see that it is actually a method instead of a property. There is a property row_count, but the rowcount method should be used.

I will look into fixing the tests

Thanks, that makes sense - so a mocking issue on the fix. Thanks for adjusting the mocks!
