Session Analysis

The Issues list page supports core CRUD and filtering workflows. All 5 tests passed, verifying that creating issues, searching by keyword/status/label, and opening issue details all function as expected. Some tests required multiple locator attempts during execution.

Coverage

• Pages: /issues, /issues?new=1, /issues?q=bug&status=, /issues?q=&status=open, /issues?label=1, /issues/4
• Features: Create new issue, Search filter, Status filter, Label filter, Issue detail view

What works

• Create issue — ET-1 Create new issue via toolbar button
• Search by keyword — ET-2 Filter issues by search keyword
• Filter by status — ET-3 Filter issues by status using combobox
• Filter by label — ET-4 Filter issues by label using dropdown
• View issue details — ET-5 Open issue detail from list

Execution Issues

• ET-2 Filter issues by search keyword — Cancel button click failed 3 times before test proceeded; likely stale element from previous drawer state
• ET-4 Filter issues by label using dropdown — Bug label link click failed 6 times with various selectors before succeeding
