Adds tests/web/db/conftest.py with a db_backends fixture parametrizing SQLite (always) + MySQL (gated on DECNET_TEST_MYSQL_URL). Surface assertions (mixin methods present + async) GREEN today; insert_tags idempotency, identity rollup projection, attacker-rollup exclusion of NULL-attacker tags xfail-gated behind E.3.3.

"""Shared fixtures for ``tests/web/db/`` — dual-backend repo testing.
|
|
|
|
The ``db_backends`` fixture parametrizes a repository instance over
|
|
SQLite (always) and MySQL (skipped when ``DECNET_TEST_MYSQL_URL`` is
|
|
unset). This is the single source of truth referenced by the design
|
|
doc's "every repo test runs against both SQLite and MySQL"
|
|
convention; new repo tests under ``tests/web/db/`` should consume
|
|
the fixture rather than instantiating their own backend.
|
|
|
|
MySQL is gated on env var rather than auto-detected because spinning
|
|
a real MySQL is heavy enough to belong in CI / live runs but not the
|
|
dev loop. Per project memory: "skip heavy test categories" in the
|
|
dev cycle.
