test: Phase 4 new dimensions — proptest, mock chaos modes, jest-axe a11y#4501
Conversation
…plan §6.3) proptest was absent from our tests. Add it as a dev-dependency (already in Cargo.lock) and property suites over the adversarial-input surfaces: - security/policy/proptest_tests.rs: classify_command / command_risk_level / is_command_allowed / check_gated_command and is_path_string_allowed never panic on arbitrary .*/unicode input; a quote-free command with an appended unquoted redirect always classifies >= Write (fail-closed floor). - encryption/core.rs: Argon2id+AES-GCM round-trips for arbitrary plaintext and any printable password (case-capped — Argon2 is deliberately expensive). Verified: cargo check -p openhuman --tests reaches the openhuman crate with zero errors from these files (proptest resolves + compiles); cargo fmt clean. The full test-binary run is deferred to CI (build-time budget). Claude-Session: https://claude.ai/code/session_01Q7PNT4bLDUuZFPkV68gj4F
… §5.3) The mock backend could only inject clean HTTP error statuses. Add two real outage shapes as rule modes: "reset" (destroy the socket → client sees a connection reset) and "malformed" (a 200 with a non-JSON body). New scripts/mock-api/chaos.test.mjs drives the real server and asserts both, plus a regression guard that the default status mode and unmatched requests are unchanged. Auto-run by the Phase 0 test:scripts job + inventory guard. Verified: node --test scripts/mock-api/** → 46 pass (5 new chaos tests). Claude-Session: https://claude.ai/code/session_01Q7PNT4bLDUuZFPkV68gj4F
The frontend had zero a11y assertions. Add jest-axe (+ @types) and an a11y smoke test running axe-core over ArtifactCard (ready + failed) and ApprovalRequestCard, asserting no violations. jsdom skips color-contrast (no layout), so this catches the structural bugs that matter — roles, labels, ARIA. Verified: vitest run a11y.smoke.test.tsx → 3 pass; eslint/prettier clean. Claude-Session: https://claude.ai/code/session_01Q7PNT4bLDUuZFPkV68gj4F

Rust Core Coverage failure is an unrelated pre-existing flake — re-running. All five new proptest tests passed in that run: The lib-test target exited 101 on a different, unrelated test: |
…env-race Under coverage instrumentation Argon2id runs ~2.5s/case, so the 24-case encrypt/decrypt round-trip property held the lib-test binary for ~60s and deterministically widened a pre-existing env-var race in the unrelated config::schema::load env-overlay tests (they mutate process-global env without per-test serialization), failing the Rust Core Coverage lane on env_overlay_toggles_agent_tracing_capture_content. The round-trip is already covered by the fixed-input tests in this module (round-trip, tamper, KDF determinism); the property-based fuzzing value stays in the fast security::policy::proptest_tests. Keep proptest as a dev-dep (still used there). Claude-Session: https://claude.ai/code/session_01Q7PNT4bLDUuZFPkV68gj4F

…ansai#4498 PR tinyhumansai#4498 flipped `default_capture_content()` from false to true (traces without content aren't actionable in Langfuse) and updated observability.rs's own test, but left config/schema/load_tests.rs::env_overlay_toggles_agent_tracing_capture_content still asserting the old `false` default. `Config::default()` now yields capture_content=true, so that first assertion is deterministically wrong — the test only *runs* on Rust-touching PRs (Rust Core Coverage lane trigger), which is why it stayed silently red rather than blocking every PR. Correct the test to the new "on by default" contract: assert the default is on, then that an env overlay can turn it off and back on. Add the env_lock() guard its sibling env-overlay tests use. Surfaced by the Phase 4 proptest PR (tinyhumansai#4501), whose Rust changes trigger the coverage lane that runs this test. Claude-Session: https://claude.ai/code/session_01Q7PNT4bLDUuZFPkV68gj4F

Summary
Phase 4 of the test-suite audit (
plan.md§5 / §6 / §7) — the new test dimensions the suitehad zero of. Unlike the §4 P0/P1 backlog (which re-verification showed was largely already covered),
these are genuinely greenfield, and all three are validated locally.
proptestas adev-dependency (already in
Cargo.lock) and property suites over the adversarial-input surfaces:security/policy/proptest_tests.rs: the command classifier + allowlist + path-string checknever panic on arbitrary/
.*/unicode input (fuzz-lite over untrusted LLM/user strings), anda fail-closed invariant — a quote-free command with an appended unquoted redirect always
classifies
>= Write.encryption/core.rs: Argon2id+AES-GCM round-trips for arbitrary plaintext + any printablepassword (case-capped, since Argon2 is deliberately expensive).
httpFaultRulescould only inject clean HTTP errorstatuses. Adds two real outage shapes as
modevalues:reset(tears the socket down →client sees a connection reset) and
malformed(a 200 with a non-JSON body). Newscripts/mock-api/chaos.test.mjsdrives the real server and asserts each mode (plus a regressionguard that the default status mode and unmatched requests are unchanged). Auto-covered by the
Phase 0
test:scriptsjob + inventory guard.jest-axeandapp/src/components/__tests__/a11y.smoke.test.tsx, running axe-core over ArtifactCard (ready +failed) and ApprovalRequestCard and asserting no violations. jsdom skips color-contrast (no
layout), so this catches the structural bugs that matter — roles, labels, ARIA validity.
Problem
plan.md§7 lists dimensions with zero coverage: property-based testing, a11y, and (in §5) themock's inability to simulate connection resets or malformed bodies. These aren't duplicate-risk like
the backlog — they're new capability.
Solution
Each dimension is small and self-contained so it stays fast/stable and can grow incrementally
(more property targets, more chaos modes, more a11y screens). Everything is validated locally:
cargo check -p openhuman --testsclean;node --test scripts/mock-api/**(46 pass incl. 5 newchaos tests);
vitesta11y smoke green (3 tests).Scope note (what's intentionally NOT here)
cargo-fuzz(needs a separate fuzz crate + nightly),cargo-mutants(a CI runner, not test code),and
criterionbenches are larger tooling efforts better landed on their own; they're left for afollow-up. The remaining §4 P0/P1 items that need the Tauri crate (blocked locally by missing system
glib-2.0) or the WDIO/Playwright harness are also out of scope here.Submission Checklist
