scripts/run_tests.sh

#!/usr/bin/env bash
# Canonical test runner for hermes-agent. Run this instead of calling
# `pytest` directly to guarantee your local run matches CI behavior.
#
# What this script enforces:
#   * -n 4 xdist workers (CI has 4 cores; -n auto diverges locally)
#   * TZ=UTC, LANG=C.UTF-8, PYTHONHASHSEED=0 (deterministic)
#   * Credential env vars blanked (conftest.py also does this, but this
#     is belt-and-suspenders for anyone running `pytest` outside of
#     our conftest path — e.g. calling pytest on a single file)
#   * Proper venv activation
#
# Usage:
#   scripts/run_tests.sh                     # full suite
#   scripts/run_tests.sh tests/agent/        # one directory
#   scripts/run_tests.sh tests/agent/test_foo.py::TestClass::test_method
#   scripts/run_tests.sh --tb=long -v        # pass-through pytest args
