# Run the agent-image test suite via pytest, with the determinism the legacy
# per-file `unittest` runner gave for free.
#
# WHY per-file isolation: a large body of these tests was written for
# `python -m unittest tests.test_x` (one process per file). Many stub
# langchain/langgraph into sys.modules at import time and bake real tool objects
# against a fake decorator during import — order-dependent in a single pytest
# process. So the gate runs each test FILE in its own pytest subprocess
# (parallelized) via tooling/scripts/pytest_isolated.py. See docs/readmes/README.TESTING.md.
#
# The whole repo is mounted at /repo (workdir /repo/agentic) so the cross-layer
# tests resolve: REPO_ROOT=parents[2]=/repo, git HEAD is available, and sibling
# dirs (capture_proxy/, recon_orchestrator/, webapp/, mcp/) are present.
#
# Usage:
#   ./agentic/run_tests.sh                 # unit gate (default) — must be 100% green
#   ./agentic/run_tests.sh unit            # same
#   ./agentic/run_tests.sh focused         # back-compat alias -> unit
#   ./agentic/run_tests.sh integration     # integration tier
#   ./agentic/run_tests.sh live            # live tier (self-skips when stack down)
#   ./agentic/run_tests.sh all             # unit + integration
#   ./agentic/run_tests.sh coverage        # unit+integration with --cov + floor
#   ./agentic/run_tests.sh tests/test_x.py [pytest args...]   # passthrough (single proc)
