"""Pytest fixture isolation for meshai persistence (v0.6-2).
|
||
|
|
|
||
|
|
Before v0.6-2 the dispatcher held all state in instance memory, so tests
|
||
|
|
that constructed `Dispatcher(...)` were inert w.r.t. SQLite. v0.6-2 made
|
||
|
|
`Dispatcher.__init__` read/restore from the persistence layer, which by
|
||
|
|
default points at `/data/meshai.sqlite`. Without isolation every test
|
||
|
|
would now read+write production state, polluting across tests and across
|
||
|
|
pytest invocations.
|
||
|
|
|
||
|
|
This autouse fixture redirects `MESHAI_DB_PATH` to a per-test tmp file
|
||
|
|
and clears the persistence-layer threading.local caches around each test.
|
||
|
|
Existing tests that don't reference any fixture get isolation for free;
|
||
|
|
tests that explicitly use a `db_path` (or similar) fixture can still
|
||
|
|
override the env var inside their own fixture body -- last setenv wins.
