`scripts/run_tests.sh tests/<dir>/` is how a change gets its regression
coverage run, so a test filed under the wrong directory is a test nobody
runs when that code changes. Two kinds of drift had accumulated.
Parallel directories for one source package, folded into the mirror:
tests/acp -> tests/acp_adapter (its __init__/conftest move with it)
tests/cli -> tests/hermes_cli (prompt_toolkit fixture merged into
hermes_cli/conftest.py)
tests/run_agent -> tests/agent (backoff fixture becomes
agent/conftest.py)
tests/relay -> tests/gateway/relay
tests/state -> tests/hermes_state
246 loose files at tests/ root, routed by the package they import/patch:
hermes_cli, hermes_state, agent, gateway, tools, plugins, tui_gateway, cron.
Installer and desktop-update script tests go to tests/scripts/{install,
desktop_update}/. 43 tests of root-level modules (batch_runner, utils,
hermes_constants, packaging) stay at the root.
Filenames drop their issue numbers (95 files: test_89315_x.py -> test_x.py);
the number stays in the module docstring where it has context.
Collisions: test_cli_skin_integration.py existed in both tests/ and tests/cli
with different subsets — merged into one (10 tests, all kept);
run_agent/test_pre_compress_memory_context.py -> agent/..._handoff.py;
tests/test_account_usage.py -> agent/test_account_usage_fetch.py;
tests/test_web_server.py -> hermes_cli/test_web_server_ws_ping.py.
Deleted: test_minisweagent_path.py (empty since PR #2804),
test_model_picker_scroll.py (tested a private copy of the logic, imported
nothing), test_process_loop_event_loop_warning.py (asserted asyncio behaviour,
imported nothing from Hermes).
Repo-root path arithmetic (Path(__file__).parents[N], dirname chains) is
bumped for the 202 files that changed depth and verified by evaluating every
such expression against the new location. classify_changes' desktop-updater
lane prefix, tests-os.yml's ignore glob and every in-tree path comment follow
the moves. tests/test_tests_tree_layout.py keeps the tree from drifting back.
test_session_not_found_goes_to_stdout_in_full_mode passes in isolation but
fails in a full tests/cli run. Two independent leaks from the same neighbor
test conspire:
1. test_cli_init.py's _make_cli() reloads cli.py while prompt_toolkit is
stubbed with MagicMocks and never reloads it back, so sys.modules['cli']
is left with a mock _pt_print/_PT_ANSI and cli._cprint silently no-ops
for every later test. Fixed by reloading cli once more with the real
modules visible (try/finally).
2. prompt_toolkit's print_formatted_text caches its Output on the
process-global default AppSession the first time it renders without an
explicit output=. Under capsys (which swaps sys.stdout per test), the
first CLI test to emit through _cprint locks that cache onto its own
captured stdout, so later capsys tests read an empty buffer. Fixed with
an autouse fixture in a new tests/cli/conftest.py that resets the cached
output around each test.
Neither change touches production code or the flaky test's own assertion.
Related to #59358 (which addresses the same flaky test by mocking _cprint in
the assertion instead; this fixes the two underlying leaks at the source and
does not modify test_resume_quiet_stderr.py).
