Run Tests

Run the plugin's test suite

This plugin uses Django's built-in test runner (django.test.TestCase), not pytest — pyproject.toml lists pytest as a test extra but the suite is invoked via NetBox's manage.py test. CI runs this exact command in .github/workflows/lint-tests.yaml.

Canonical command

From the NetBox repo root (with the plugin installed in editable mode and testing/configuration.py linked into NetBox):

python netbox/manage.py test netbox_branching.tests --keepdb

This is the same command CI runs. Add -v 2 to print each test as it executes; drop to -v 1 for terser output.

Prerequisites (one-time setup)

1. NetBox checkout alongside this repo (../netbox or any sibling path).
2. testing/configuration.py symlinked into NetBox:

   ln -sf "$PWD/testing/configuration.py" ../netbox/netbox/netbox/configuration.py
   

   This config sets PLUGINS = ['netbox_branching'], wraps DATABASES with DynamicSchemaDict, adds BranchAwareRouter to DATABASE_ROUTERS, and points at a local Postgres + Redis on default ports (netbox / netbox / netbox).
3. Plugin installed in editable mode with test extras:

   pip install -e '.[dev,test]'
   

4. NetBox dependencies installed: pip install -r ../netbox/requirements.txt.
5. Postgres + Redis reachable on localhost (defaults).

If any of these are missing, surface the gap to the user — do not silently skip.

Useful variants

Run a single test module / class / method (Django's dotted-path target):

python netbox/manage.py test netbox_branching.tests.test_branches --keepdb
python netbox/manage.py test netbox_branching.tests.test_api --keepdb
python netbox/manage.py test netbox_branching.tests.test_iterative_merge.IterativeMergeTestCase --keepdb

Available test modules in netbox_branching/tests/:

• test_api — REST API endpoints (CRUD, sync/merge/revert/migrate actions).
• test_branches — Branch model operations and lifecycle.
• test_changediff — ChangeDiff conflict detection.
• test_config — Plugin configuration validation.
• test_connection_lifecycle — Database connection management.
• test_events — BranchEvent creation.
• test_filtersets — Filterset behaviour (FK _id filters, etc.).
• test_iterative_merge — Iterative merge strategy (comprehensive).
• test_query — Branch-aware query routing.
• test_related_models — Related model handling across schemas.
• test_request — Request-level branch context.
• test_squash_merge — Squash merge strategy (comprehensive).
• test_sync — Branch sync operations (comprehensive).
• test_views — UI views via NetBox's test client.

Stop on first failure: --failfast. Run in parallel: --parallel auto (note: --keepdb and --parallel don't always compose cleanly).

After model changes

Generate migrations before running tests, otherwise the test DB build will fail:

python netbox/manage.py makemigrations netbox_branching

Why these choices

• Don't substitute pytest. The suite uses django.test.TestCase; pytest would need pytest-django configured against NetBox's settings, which nobody has set up. Run via manage.py test to match CI.
• Always use --keepdb. Branch schema provisioning and teardown hit a real PostgreSQL database. Recreating the test DB on every run is slow and unnecessary; --keepdb preserves it between runs.
• Don't mock the database. Tests exercise the real ORM, views, and APIs end-to-end. The whole point of this plugin is schema-level database isolation — a mocked DB can't exercise that.
• Match CI's invocation. If a test passes locally but fails in CI, the first diagnostic is "did you run the same command?" — keeping the canonical form identical removes that variable.
