"""Shared fixtures for end-to-end tests.

Since the CLI server refactor (#1545), ``pyrit_scan`` is a thin client that
talks to a separate ``pyrit_backend`` process; it exits with an error if no
server answers on ``http://localhost:8000``. The session-scoped fixture
below launches a backend once per test session so the scenario tests can
keep invoking ``pyrit_scan_main`` directly without any CLI changes.

    Uses the same ``test_config.yaml`` the scenario tests pass to the CLI

    Tear down via ``launcher.stop()`` so a lingering subprocess does not
    occupy port 8000 between local pytest runs. The launcher is a no-op if
    a backend is already healthy on the port (e.g. a developer has one
    running), so this fixture also remains friendly to local iteration.
