Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Context
internal/handlers/handlers_test.gocurrently covers Health and Dashboard (no-token path). The integration test file covers a broader set but many handlers lack unit-level coverage for error paths, HTMX partial responses, and write operations (create issue, apply label, submit review, set state).What to do
Add test cases to
handlers_test.go(or a newhandlers_write_test.go) covering:POST /issues— CreateIssue returns 303 redirect on success, 400 on missing fieldsPOST /issues/{owner}/{repo}/{index}/labels— ApplyLabels returns HTMX fragmentPOST /issues/{owner}/{repo}/{index}/state— SetIssueState returns correct fragment for open/closedPOST /pulls/{owner}/{repo}/{index}/review— SubmitReview returns 200 on successPOST /pulls/{owner}/{repo}/{index}/state— SetPullState returns correct fragmentGET /issues/{owner}/{repo}/{index}— IssueDetail with HX-Request header returns partial, without returns full pageUse the mock HTTP server pattern established in

Triage (2026-04-19)
Assigned to: AI-QA
Status: Ready for implementation. Existing tests in
handlers_test.goandintegration_test.gocover 43 integration tests. This issue asks to expand unit test coverage to all routes. No blockers.Sprint planning update: Item 6 (IssueDetail with HX-Request header) is closely related to #196 which implements the fragment return logic in the detail handlers. Coordinate with #196 — either implement the fragment logic as part of this issue or have this issue depend on #196 merging first.
Sprint planning update (2026-04-20): All items 1-5 from the checklist are now covered in
internal/handlers/integration_test.go:TestIntegration_CreateIssue_Valid,TestIntegration_ApplyLabels_Valid(+ HTMX variant),TestIntegration_SetIssueState_Close(+ HTMX + Reopen variants),TestIntegration_SubmitReview_Approve(+ HTMX + RequestChanges),TestIntegration_SetPullState_Close.Item 6 (IssueDetail HTMX partial fragment) is tracked separately in #196. Closing this issue as the original scope is complete.
