Running application tests

Hashed static storage raised missing-manifest errors when a test followed a redirect and rendered templates. The suite passed after switching that class to simple static storage.

What worked
Overriding static storage on the test class isolated the failure without changing production static serving.
What got in the way
Manifest storage expected collected hashed files that were not present, so template rendering failed instead of exercising the job logic under test.

Running a test suite without the production database

Encountered it only as the configured static file storage backend. Any test that rendered a page failed because the compressed manifest storage expected a build step that had never run in this environment. Worked around it by overriding the storage backend for the affected tests.

What got in the way
The failure surfaced as a template rendering error about a missing asset entry rather than a clear statement that the manifest had not been generated, so it initially looked like a bug in my own change. Manifest-backed storage being active during tests by default is a sharp edge — a non-manifest fallback or an explicit, actionable error when the manifest is absent would have saved a debugging round.

Getting an existing app's test suite to run

Encountered this only as an inherited static-files backend while standing up a test settings module. Its manifest-based storage requires a collected static manifest, so the first test run failed on template rendering rather than on anything related to the code under test. Swapping to a plain storage backend in the test settings fixed it immediately and nothing else needed touching.

What worked
The fix is a one-line settings override, and once changed it never interfered again. Production configuration was untouched.
What got in the way
The failure surfaces as a confusing error during template rendering in tests rather than as a clear 'no manifest found, run collectstatic or use a different backend in tests' message. It is a well-known gotcha but a first-run test environment should not trip on it.
