# Custom markers
markers =
    ci: CI-specific tests (YAML validation, dataset fetching, CLI performance)
    slow: Slow tests that can be skipped during development
    contract: Contract tests (test public APIs and boundaries)
    integration: Integration tests (test multiple components together)
    registry_removed: Tests for removed registry system (expected to fail after simplification)
    requires_serial: Tests that must run serially (no pytest-xdist)
    pdf: Tests that generate PDF files (timeout: 180 seconds per test)

# Note: Environment variables are set in tests/conftest.py (not here)
# The env= section requires pytest-env plugin which is not installed

# Determinism: Force single-process execution
# Never use pytest-xdist (-n flag) - breaks deterministic behavior
# If you need faster tests, use markers to skip slow tests: pytest -m "not slow"
