Ranked by the time each fix saves per run

Use a fast password hasher in tests

21.2s (32% of test time) is spent hashing passwords. Slow hashing protects real passwords; in tests it only burns CPU.

High Password hashing

20.15 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

Use plain static file storage in tests

Static file storage/manifest handling costs 15.7s.

High App code

15.74 s per run

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

Stop re-running migrations on every test run

Migrations take 17.2s per run, before the first test can start.

High Migrations

15.51 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 20.6s in total (password hashing 20.4s, db 158ms, factories 12ms) in 7 classes: TestPostAnnouncements (6 tests), TestFollowStarterPack (3 tests), TestConferenceApprovalVisibility (5 tests), TestApproveConference (6 tests).

High Database

14.42 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.

Documentation

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

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

High Database

7.85 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_invalid_selected_instance: SELECT "confs_conferencetag"."id", "confs_conferencetag"."name", "confs_conferencetag"."slug", "confs_conferencetag"."icon" FROM "confs_conferencetag" WHERE "confs_conferencetag"."slug" = %s LIMIT ? FOR UPDATE

Disable django-debug-toolbar in tests

django-debug-toolbar is installed in the test settings and costs 5.9s.

Medium App code

5.92 s per run

Documentation

Make the test database server skip durability work

Tests spend 28.6s (43%) in the database. Test databases don't need to survive a crash, so the server can skip flushing to disk.

Medium Database

5.73 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.

Documentation

pytest takes a long time before the first test runs

Startup takes 7.1s and collection 3.4s on every run, even when you only run one test.

Medium Imports

4.17 s per run

Fix: Set testpaths and norecursedirs (node_modules, .venv, build, docs) so pytest doesn't walk unrelated directories; move heavy imports out of module level in test files and conftest.py into fixtures; check `python -X importtime -m pytest --collect-only -q` for the slowest imports.

pytest-xdist workers finish at very different times

The busiest worker ran 20.7s of tests, the least busy 14.7s.

Medium Parallelism

3.00 s per run

Fix: Use --dist worksteal (pytest-xdist 3.2+) so idle workers take tests from busy ones; if you use --dist loadscope/loadfile, split the biggest classes or modules.

Details

Documentation

Run migrations once, not once per worker

Each of the 4 pytest-xdist workers builds its own test database by running every migration: 18.6s in total, about 4.6s per worker. 13.9s of it repeats work another worker already did.

Medium Migrations

13.94 s per run

Fix: Migrate once and copy the database: let one worker build the test database and have the others create theirs from it as a template (on PostgreSQL, CREATE DATABASE ... TEMPLATE ..., which copies files instead of running migrations). Django's own test runner already does this with --parallel.

Details

Every copy is built by the same migrations, so a broken migration still fails the run.
