Fix next

Ranked by the time each fix saves per run

Run tests in parallel on all 2 CPUs

Tests run one at a time: 26.6s of test time on a 2-CPU machine. With pytest-xdist this could take about 13.3s.

High Parallelism

13.31 s per run

Fix: pip install pytest-xdist, then run pytest -n auto (add it to addopts, or only in CI). pytest-django creates a separate test database per worker automatically. Read the guide

Details

Tests must not share state: files in fixed paths, ports, a shared database without per-worker names, or module globals. Run with -p randomly first to shake out order dependencies.

Documentation

Use plain static file storage in tests

Static file storage/manifest handling costs 12.2s.

High App code

12.18 s per run

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

Disable django-debug-toolbar in tests

High App code

Documentation

Make the test database server skip durability work

Tests spend 16.6s (62%) in the database. Test databases don't need to survive a crash, so the server can skip flushing to disk.

High Database

3.32 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. Read the guide

Details

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

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

27 tests run the same query 10+ times, e.g. 180x in test_seed_demo. N+1 queries slow the tests and production alike.

High Database

3.17 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). Read the guide

Details

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

Documentation

Stop re-running migrations on every test run

Migrations take 2.7s per run, before the first test can start.

Medium Migrations

2.47 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. Read the guide

Details

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

Documentation

pytest takes a long time before the first test runs

Startup takes 5.8s and collection 303ms on every run, even when you only run one test.

Medium Imports

2.45 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. Read the guide

Details

.venv/bin/pytest (303ms)
.venv/bin/pytest (5.8s)

Documentation

Use a fast password hasher in tests

2.0s (8% of test time) is spent hashing passwords. Slow hashing protects real passwords; in tests it only burns CPU.

Medium Password hashing

1.91 s per run

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

Details

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

Documentation

Use TestCase instead of TransactionTestCase

1.2s goes to flushing every table after tests in 11 TransactionTestCase / transaction=True / live_server tests.

Medium DB schema

1.06 s per run

Fix: Use django.test.TestCase (or @pytest.mark.django_db without transaction=True): it wraps each test in a transaction and rolls back instead of truncating every table. Keep TransactionTestCase only for tests that need real commits (on_commit hooks can use TestCase.captureOnCommitCallbacks). Read the guide

Details

Tests that rely on commit behaviour, multiple connections or a live server still need a transactional test case.

Documentation

Tests open new database connections over and over

Connecting to the database takes 1.0s.

Medium Database

806 ms per run

Fix: Reuse connections: create the engine once per session (not per test) and keep the default pool (NullPool reconnects on every checkout); in Django avoid closing connections in tests (connection.close()/close_old_connections). Read the guide

Create shared test data in setUpTestData instead of setUp

setUp() runs before every test and takes 933ms in total (db 874ms, library 47ms, factories 6ms) in 14 classes: SettingsTest (3 tests), ProjectsPageTest (5 tests), ProjectEditPage (6 tests), ProjectDeletePage (4 tests).

Low Database

653 ms 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). Read the guide

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.
