🐛 Fix parse errors in context test files#4255
Conversation
…>5% drop If coverage drops more than 5% from the previous badge value: 1. Badge is NOT updated (prevents showing regressed value) 2. An issue is automatically opened with diagnostics This prevents the badge from bouncing between values when squash merges corrupt test files or coverage shards fail to upload.

Pull request overview
This PR primarily repairs broken frontend test files (parse errors from a squash merge) and adjusts/extends hook test coverage; it also updates the scheduled coverage workflow to add a coverage-regression guard.
Changes:
- Restores/fixes multiple hook test suites (LLM-d, Kagent backend, ArgoCD) so they parse and run again.
- Removes the broken
AlertsContext-deeptest file. - Adds a regression guard to the hourly coverage badge update workflow (including optional issue creation on large drops).

The regression-guard branch attempts to create a GitHub issue using the same github-token configured for gist updates (secrets.GIST_TOKEN). If that token lacks repo/issues:write scope (common for gist-only PATs), issues.create will fail, but the script still returns—so the badge will not be updated and no alert will be raised. Consider using GITHUB_TOKEN for the issue creation path (and add permissions: issues: write), or use a separate secret token with confirmed issue permissions; also only skip updating the badge if the notification step succeeds (or fall back to updating + logging a warning).

The workflow will open a new issue on every scheduled run while coverage remains below the previous badge by >5%. Without any deduplication (e.g., searching for an existing open issue with the same title/label and updating it), this can spam the repo. Add an idempotency check (search issues by label/title and only create if none open) or update/comment on an existing issue.

This test claims to hit the hook’s outer try/catch and increment consecutiveFailures, but the error thrown by kubectlProxy.exec is handled by the inner per-cluster catch, after which the hook unconditionally calls setConsecutiveFailures(0). As written, the test can’t validate the stated behavior and doesn’t assert consecutiveFailures at all. Either rename the test to reflect what it actually verifies (graceful handling of exec exceptions) or adjust the setup to trigger the outer catch and assert the expected consecutiveFailures change.

The test name says it reports healthy=false when consecutiveFailures >= 3, but it only asserts the default healthy state when failures are 0. This is misleading and makes it harder to understand what coverage is actually being added. Rename the test to match the assertions, or (if feasible) set up the hook state to reach consecutiveFailures >= 3 and assert the unhealthy behavior.

PR description focuses on fixing parse errors in test files, but this PR also changes the coverage workflow behavior (adds a regression guard and potential issue creation). If intentional, please update the PR description to call out this operational change so reviewers know to evaluate it explicitly.
