There seems to be an issue with the updated version of tox and the use-current-env plugin.
This should be fixed in: #184

[ambarrio]

Great job!

One test crashing. Is the tox thing you found?

[johandahlberg]

This looks good to me - I am a little bit concerned that some of the numeric the test results are changing. Do you have any feel for why that is?

[fbdtemme]

I have made a new test data generation run to test the new meta.json files.
These very small numerical changes are common whenever the testdata is rerun.
After the scope change of this ticket it is actually not needed to update the testdata so I'll drop that from the PR.

The test failures should indeed be fixed with the tox PR that is now merged.
