131 test modules sat next to the code they test; instances alone had 51 of them beside views.py and utils.py. They move into a tests/ package per app, and the JavaScript checks into webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py; the empty generated stubs are removed. Imports of the app's own modules become absolute, paths built from __file__ go one level up, the live helper is instances.tests.livetest, and coverage omits */tests/*. The suite discovers the same 960 tests as before.
