Schema caching tests broken on Python 3.6 and 3.7 #52

Closed simonw closed 4 years ago

simonw commented 4 years ago

Broken due to #51 commit https://github.com/simonw/datasette-graphql/commit/ae717857cde97db4a52054310b029bf8ba222d7c

Tests pass in 3.8, fail in 3.6 and 3.7.

Testing on my laptop:

% source /tmp/python36env/bin/activate
% cd Dropbox/Development/datasette-graphql 
datasette-graphql % pip install -e '.[test]'
...
% pytest

I wonder if this is the problem: https://docs.python.org/3/library/unittest.mock.html#patch

Changed in version 3.8: patch() now returns an AsyncMock if the target is an async function.

I'm going to only run the template tag test on Python 3.8 or higher, rather than figure out how to get async mocking working on older Pythons.
