Use plain static file storage in tests

Static file storage/manifest handling costs 47.8s.

High App code

47.76 s per run

Fix: In test settings use STORAGES["staticfiles"] = {"BACKEND": "django.contrib.staticfiles.storage.StaticFilesStorage"} so templates don't need a manifest.

Use a fast password hasher in tests

48.7s (32% of test time) is spent hashing passwords. Slow hashing protects real passwords; in tests it only burns CPU.

High Password hashing

46.25 s per run

Fix: In your test settings set PASSWORD_HASHERS = ["django.contrib.auth.hashers.MD5PasswordHasher"] (currently PBKDF2PasswordHasher).

Details

Only change the hasher in test settings. Tests that assert on a specific hash format need updating.

Documentation

Stop re-running migrations on every test run

Migrations take 37.1s per run, before the first test can start.

High Migrations

33.39 s per run

Fix: Run with --reuse-db (add it to addopts in pytest.ini/pyproject) so the test database survives between runs; pass --create-db when migrations change. If no test depends on data migrations, --nomigrations builds the schema straight from the models, which is faster still.

Details

CI should still build the database from scratch (no --reuse-db) so broken migrations are caught.

Documentation

Create shared test data in setUpTestData instead of setUp

setUp() runs before every test and takes 47.2s in total (password hashing 46.9s, db 311ms, factories 19ms) in 7 classes: TestPostAnnouncements (6 tests), TestFollowStarterPack (3 tests), TestCreateConference (10 tests), TestConferenceApprovalVisibility (5 tests).

High Database

33.07 s per run

Fix: Move object creation that tests only read from setUp() into `@classmethod def setUpTestData(cls)`: it runs once per class and each test still sees the original rows (TestCase rolls back to a savepoint).

Details

Since Django 3.2 attributes assigned in setUpTestData are deep-copied per test, so in-memory changes don't leak between tests. Keep objects a test modifies in the database (or re-fetches) as before.

Repeated queries (N+1) in the code under test

10 tests run the same query 10+ times, e.g. 45x in test_single_facet_is_indexable. N+1 queries slow the tests and production alike.

Medium Database

12.64 s per run

Fix: Django: fetch related rows in one query with select_related() for foreign keys and prefetch_related() for reverse/many-to-many relations, then lock the count in with assertNumQueries (or pytest-django's django_assert_num_queries).

Details

This changes application code, so it speeds up production too; the tests stay as they are.

45x in test_single_facet_is_indexable: SELECT "confs_conferencetag"."id", "confs_conferencetag"."name", "confs_conferencetag"."slug", "confs_conferencetag"."icon" FROM "confs_conferencetag" WHERE "confs_conferencetag"."slug" = %s LIMIT ? FOR UPDATE

Documentation

Make the test database server skip durability work

Tests spend 52.8s (35%) in the database. Test databases don't need to survive a crash, so the server can skip flushing to disk.

Medium Database

10.57 s per run

Fix: For a PostgreSQL test server (Docker/CI service) start it with -c fsync=off -c synchronous_commit=off -c full_page_writes=off, and put its data directory on tmpfs; for MySQL use --innodb-flush-log-at-trx-commit=0 --skip-log-bin. Never on a server with data you need.

Details

Only affects crash safety of the throwaway test server; query behaviour is identical.

Disable django-debug-toolbar in tests

django-debug-toolbar is installed in the test settings and costs 9.9s.
