Conversation
The squash merge of PR #4223 truncated 23 test files (missing closing braces, duplicate imports). This caused 8-10 shard failures per coverage run, dropping reported coverage from 53% to 12-32%. Restored all files from the original fix/coverage-tests branch where all tests passed. Also fixed auth.test.ts duplicate renderHook import. Signed-off-by: Andrew Anderson <andy@clubanderson.com>

This hunk deletes a large block of tests (consecutive failures/error state + additional useLLMdServers edge cases). Given the PR goal (“restore truncated test files / fix shard failures”), removing coverage here looks inconsistent and may reintroduce untested behavior. If these tests were intentionally removed to address flakiness, please document the rationale in the PR description; otherwise restore the deleted describes/tests so the file isn’t effectively re-truncated.

This test asserts that an OK API response with { items: [], isDemoData: false } should fall back to mock/demo data. That contradicts the hook implementation: useArgoCDApplications explicitly uses real data even when the list is empty (treats it as “ArgoCD installed but no apps yet”). Update the expectations to isDemoData === false and applications length 0 (or change the hook behavior if that’s what you intend, but then its in-code comment about #4201 would also need updating).

This test expects a successful API response with all-zero health stats (isDemoData: false) to fall back to demo data. The hook useArgoCDHealth currently treats zero totals as valid real data (ArgoCD installed but no apps) and sets isDemoData to false. Adjust the test to expect isDemoData === false, total === 0, and healthyPercent === 0 (or update the hook if behavior has changed).

This test expects an OK API response with zero sync totals (stats: {synced:0,outOfSync:0,unknown:0}, isDemoData:false) to fall back to demo data. The hook useArgoCDSyncStatus explicitly uses real data even when totals are zero (see comment about #4201). Update the test expectations to isDemoData === false and total === 0 (and percents 0), unless the hook behavior is intended to change.
