Root-cause and deterministically fix the recurring 5s-timeout flakes that
surfaced under v8-instrumented, concurrent load. All fixes are test-only; no
product source changed. No test was skipped or disabled, and the per-file
coverage gate (>=90 on all four dims) still holds.
Common root cause across the modal/form/screen suites: userEvent.setup()
schedules a real setTimeout between keystrokes. Under CPU contention those
yields balloon, so multi-field interactions blew past the 5s per-test
timeout. Fix: userEvent.setup({ delay: null }) removes the per-keystroke
real-timer dependence (typing dispatches synchronously), making the suites
load-independent.
Per file:
- ServerConfigModal / ServerImportConfigModal / ServerImportJsonModal /
ResourcesScreen / InspectorView: userEvent.setup({ delay: null }).
- PromptArgumentsForm (completions): replaced wall-clock sleeps sized just
past the 300ms completion debounce (await setTimeout(400)) — which race
the debounce timer under load — with awaited conditions (findBy/waitFor)
on the real rendered outcome, plus delay:null. Negative assertions now
lean on the component's synchronous state/timer teardown instead of a
timed window, so they are deterministic regardless of machine speed.
- inspectorClient integration "tracks stderr logs": the child's stderr is
piped out-of-band from the tool's JSON-RPC response, so reading the log
synchronously after callTool raced the stderr chunk. Wrapped the assertion
in vi.waitFor so it polls until the line lands.
Verified: web validate + 6x test:coverage (4 sequential + 2 concurrent
under load) + standalone test:integration, all green (229 files / 3237
tests per coverage run; 799 integration tests), zero intermittent failures.
