Tests fail on AWS because of IOErrors #27
Description
Describe the bug
Running the test suite on AWS results in a number of failed tests. The consistent theme are IO errors. These are likely caused by us mounting nitelite.test-data/output, not just nitelite.test-data/input, and there are strong restrictions on writing to mounted directories.
To Reproduce
Run with default options, except with the environment variable RUN_TESTS set to true.
Expected behavior
No errors in the tests.
