Keep the two tests that pin the user-facing contract (a file-backed
list bypasses discovery; `-` reads stdin). The mutual-exclusion and
unreadable-path error tests exercised argparse plumbing already covered
by the runner's flag-routing contracts and pushed the suite past the
salvage bar of two invariant tests per fix.
--files carries the whole list as one argv element, and Linux caps a
single argument at MAX_ARG_STRLEN (128 KiB) - a much smaller limit than
ARG_MAX. The whole-suite list (~210 KB) dies with E2BIG in execve before
the runner's first line runs, so 'run the whole suite except one file'
cannot be expressed through --files at all.
Add --files-from PATH (or '-' for stdin), one path per line, mutually
exclusive with --files. A bare '-' after --files-from is normalized to
the '='-joined form because argparse treats '-' as a positional.
When a per-file pytest subprocess dies by signal (the sqlite cross-thread
close in #113186 was a SIGSEGV after every test had passed), faulthandler
prints "Fatal Python error: Segmentation fault" and no summary line, so
every count parses to 0. The runner filed that under "1 file where no
tests ran (collection/import error, ...)" beneath a summary that read
"0 failed" and exited 1 — two wrong diagnoses for one real bug, and it
was misread as a runner problem twice on main.
The runner now detects a signal death or a "Fatal Python error:" banner,
prefixes the captured output with the diagnosis (same convention as the
timeout path), marks the progress line CRASHED, counts "N files CRASHED"
on the summary line, lists the file in its own failure bucket, and no
longer trips the "NO TESTS RAN" guard for a crash that ran tests. The
flake retry already covers crashes (any non-zero rc), so nothing changes
there.
The bare-flag check asked pytest's parser which tokens it does not know,
but wrapped parse_known_args in the same blanket except that guards
parser construction. A known flag with a missing value (`--tb` alone)
raises pytest.UsageError there, which the except turned into "nothing
unknown", so discovery ran and every per-file pytest died with
"argument --tb: expected one argument".
Keep the fallback around building the parser only; let parse_known_args
run outside it and surface UsageError (and the unknown-token list) as
this runner's own usage error before discovery. One invariant test.
A bare token this runner does not own used to be forwarded to every per-file
pytest, so a typo (`--jbs`, or `--help` before #114065's fix) discovered the
whole suite and each file died with "unrecognized arguments" — hours to learn
about a typo. Validate the bare passthrough tokens against pytest's own
argparse parser (installed plugins loaded), and fail once with this runner's
usage (exit 2) before discovery. argparse handles the attached-short-value
(`-rA`), combined-flag (`-xvs`) and `-k expr` forms, so real pytest flags keep
passing through; tokens after a literal `--` are the caller's explicit choice
and are never validated. If pytest's parser cannot be built, the check is
skipped and behaviour is unchanged.
Follow-up to KoNit-K's `-h`/`--help` interception (#114065). Fixes#114059.
`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.
