Systematic prune per AGENTS.md test policy, one pass over every major test tree (gateway, hermes_cli, tools, agent, run_agent, plugins, cli, cron, tui_gateway, honcho/openviking, root-level): - DELETE: source-reading tests (read_text/getsource on prod files), change-detector tests (exact catalog counts, model-name snapshots, config version literals), mock-echo tests (assert a mock returns what it was told), assertion-free/trivial tests, near-duplicate parametrizations (boundaries + one representative kept), async/sync twin duplicates, cosmetic within-file variations. - KEEP (mandatory): security/redaction/approval guards, message-role alternation invariants, prompt-caching/deterministic-call-id invariants, issue-number regression tests (deduped), E2E tests. - 6 test files deleted outright (script-style/no-assert or fully redundant); conftest.py, fakes/, fixtures/ untouched. - tests/acp/conftest.py added: autouse fixture stubs the live models.dev/GitHub/Copilot/Anthropic inventory fetches that ACP server tests performed on every session create — test_server.py 147s → 3.4s, and the tests are now genuinely hermetic. - Sleep-based slowness shrunk where safe (codex_ttfb_watchdog, compression_concurrent_fork, etc.); no wall-clock assertion tightened. Verification: full hermetic suite via scripts/run_tests.sh — 2439 files, 31,130 tests passed, 0 failed, 0 flaky retries, 315s wall (baseline: 583s wall, 13,564s subprocess CPU).

"""Tests for get_hermes_home() profile-mode fallback warning.
|
|
|
|
Regression test for https://github.com/NousResearch/hermes-agent/issues/18594.
|
|
|
|
When HERMES_HOME is unset but an active_profile file indicates a non-default
|
|
profile is active, get_hermes_home() should:
|
|
1. STILL return ~/.hermes (raising would brick 30+ module-level callers)
|
|
2. Emit a loud one-shot warning to stderr so operators can diagnose
|
|
cross-profile data contamination after the fact.
|
|
|
|
The warning goes to stderr directly (not through logging) because this
|
|
function is called at module-import time from 30+ sites, often before the
|
|
logging subsystem has been configured.
