When trying to create a resource via toolkit.get_action("resource_create"), I trigger the IDomainObjectModification interface, which calls Datastorer's notify method (https://github.com/okfn/ckanext-datastorer/blob/master/ckanext/datastorer/plugin.py#L25).

I have seen this error before when running the datastorer and the harvester together. However, it has not been fixed yet. I am afraid that you have to disable the datastorer when running the tests that are not yet related to the datastorer. When you have to tests the datastorer in the future, run the from the datastorer and not ckan (just like the datastorer tests do at the moment).

Also, since we have talked about your plans a few months ago, you could have a look at the datapusher which will replace the datastorer soon. Hopefully, I'll be able to write the remaining bits in the next month. So, if you don't have a deadline in the next month, it might be worth using the datapusher as it is much nicer than the datastorer.
