Pull request overview
Adjusts the web test coverage configuration to avoid artificially inflating the coverage denominator, and substantially expands the Vitest test suite with deep/edge-case tests across hooks, contexts, and shared UI card components.
Changes:
- Removed
coverage.all=truefromweb/vite.config.tsto prevent coverage denominator inflation. - Added/expanded extensive unit tests for UI card components, theme utilities, demo mode, and many hooks/contexts (including many edge cases).
- Added new test suite for
useClusterGroupsand deepened coverage for several existing hook test files.

There was a problem hiding this comment.
The assertion expect(postCalls.length).toBeGreaterThanOrEqual(0) is always true, so this test doesn't validate heartbeat behavior. Make it deterministic (e.g., advance timers past the heartbeat interval and assert at least one POST call, or assert that no POST occurs when demo mode is off).

expect(true).toBe(true) makes this test pass regardless of whether timers were actually cleaned up. Consider asserting observable behavior (e.g., spy on clearTimeout/clearInterval, or verify no further fetch/poll calls after unmount when timers advance).

This test is intended to cover the “max reconnect attempts exhausted” path, but it only triggers the first reconnect and then asserts reconnectAttempt <= MAX_RECONNECT_ATTEMPTS, which will always be true. To actually validate the behavior, drive the hook through MAX_RECONNECT_ATTEMPTS reconnect cycles (with fake timers + a WebSocket mock that creates new instances per reconnect) and assert the final status === 'error' and the expected error message.

There was a problem hiding this comment.
The hook reads the auth token from STORAGE_KEY_TOKEN (which resolves to the literal key 'token'). Hardcoding 'token' here works today, but it duplicates a storage convention and will silently break if the constant ever changes. Prefer importing STORAGE_KEY_TOKEN (or mocking the constants module and using the mocked value) so the test stays aligned with production behavior.
