langbot-testing	Test LangBot WebUI and core product flows with an automated browser and backend logs. Use when validating the configured LangBot frontend, pipeline Debug Chat, model provider setup and test buttons, bot and knowledge-base UI flows, or troubleshooting failed LangBot end-to-end tests.

LangBot Testing

Use this skill when an agent needs to verify LangBot behavior through the WebUI instead of only reading code.

Routing

• General WebUI testing: read references/web-ui-testing.md.
• Pipeline Debug Chat: read references/pipeline-debug-chat.md.
• Dify AgentRunner: read references/dify-agent-runner.md.
• Model provider setup or test button: read references/model-provider-testing.md.
• Plugin install/runtime/tool/page smoke: read references/plugin-e2e-smoke.md.
• Local Agent Runner: read references/local-agent-runner.md.
• Local Agent Runner path coverage: read references/local-agent-runner-coverage.md.
• Diff-aware AgentRunner QA after code changes: read references/agent-runner-qa-workflow.md.
• Agent Runner release gate: read references/agent-runner-release-gate.md.
• Sandbox-backed skill authoring: read references/sandbox-skill-authoring.md.
• LangRAG knowledge bases: read references/langrag-knowledge-base.md.
• MCP stdio tool testing: read references/mcp-stdio-testing.md.
• Performance, reliability, or chaos probes: read references/performance-reliability-testing.md.
• Drive a live instance over MCP (not raw HTTP): use the langbot-mcp-ops skill — the instance exposes an MCP server at http://<host>:5300/mcp (reuses API keys). Useful for setting up bots/pipelines/models as test fixtures programmatically.
• Known failures and fixes: read references/troubleshooting.md.
• Reusable test groups: run bin/lbs suite list and bin/lbs suite plan <suite-id> before manually assembling a case set.

Rules

• Read ../.env first and use LANGBOT_FRONTEND_URL and LANGBOT_BACKEND_URL instead of hardcoded ports.
• If a standalone frontend dev server is running, LANGBOT_FRONTEND_URL may point to LANGBOT_DEV_FRONTEND_URL; otherwise it may point to the backend WebUI.
• Confirm the backend and frontend are actually running before testing.
• Run bin/lbs fixture check before fixture-heavy MCP, RAG, multimodal, or plugin smoke tests.
• For runner externalization release checks, run bin/lbs test run agent-runner-release-preflight before the full agent-runner-release-gate suite so configuration blockers are separated from product failures.
• Read Manual Readiness in bin/lbs test plan <case-id>; manual_check means the declared preconditions or setup still need operator confirmation for this run.
• Use an authenticated browser profile prepared by langbot-env-setup.
• Do not expose API keys, OAuth secrets, tokens, or localStorage token values in output.
• A WebUI test is not complete until the visible UI result is checked against backend logs or network behavior.
• A performance result is not complete without metrics evidence and a clear split between LangBot overhead and external provider/tool/network time.
• A chaos or reliability result is not complete until the fault scope, cleanup, and recovery checks are recorded.
• For a suite, use bin/lbs suite start <suite-id> to create the suite evidence root, per-case directories, and suite-start.json/suite-start.md handoff files; use bin/lbs test result <case-id> to write final per-case result.json, then run bin/lbs suite report <suite-id> --evidence-dir <dir>.
• Do not mark a case pass until test result --evidence covers every value in the case's evidence_required.
• For runner-specific Debug Chat cases, use the case-specific pipeline env declared by automation_pipeline_url_env / automation_pipeline_name_env; do not silently reuse a generic LANGBOT_PIPELINE_URL.
