I had a look at this issue and it seems that our tests may not be 100% independent - sometimes these tests succeed when when they run in a particular order, but not when run independently

[mineo]

I just ran all test files on their own with

for i in test/test_*.py; do
   python -m unittest $(basename ${i/\//.} .py)
done

and it looks like test_submit.py is the only one that fails. It seems to require test_requests.py (or maybe other that make the correct calls) to have run before.
