From 0c5278a6ef0cde753847b74c0333b0d0ec87665c Mon Sep 17 00:00:00 2001 From: openhands Date: Wed, 10 Jun 2026 09:08:06 +0000 Subject: [PATCH] test: add mock-LLM e2e coverage for recent PRs (2026-06-10) Add two new mock-LLM E2E spec files covering features merged in the last 24 hours that lacked end-to-end test coverage: - mock-llm-drawer-and-empty-states.spec.ts (PR #1288): - Browser chrome bar renders with URL placeholder in empty state - Terminal tab shows empty state message - Tab switching between browser, terminal, and files tabs - VS Code drawer link visibility in tab bar - mock-llm-tool-visualizers.spec.ts (PR #1246): - Bash/terminal tool visualizer renders command and output - File editor tool visualizer renders file path and diff content - Agent reply renders correctly after tool call events Both specs use the page.route() mock-conversation pattern established in mock-llm-ui-regressions.spec.ts, matching existing test conventions.
