📝 Summary

What does this PR do and why?
Implements a comprehensive policy testing and simulation sandbox for the MCP Context Forge, enabling developers to test, validate, and simulate policy decisions before deployment.
implementation of Issue #2226: Policy testing and simulation sandbox**

  • Backend Service: Complete sandbox service with mock data integration and policy simulation engine
  • API Endpoints: RESTful endpoints for test case management, batch execution, and regression testing
  • Admin UI Suite: Four major UI components for visual policy testing and management
  • Testing Framework: 30+ comprehensive unit tests covering all sandbox functionality


🏷️ Type of Change

  • Bug fix
  • Feature / Enhancement
  • Documentation
  • Refactor
  • Chore (deps, CI, tooling)
  • Other (describe below)

🧪 Verification

Check Command Status
Lint suite make lint ⏳ Will run in CI/CD
Unit tests make test ⏳ Will run in CI/CD
Coverage ≥ 80% make coverage ⏳ Will run in CI/CD

Note: Local Windows environment had compatibility issues with make commands. Code has been formatted with Black and isort directly. CI/CD pipeline will validate all checks.


✅ Checklist

  • Code formatted (make black isort pre-commit)
  • Tests added/updated for changes
  • Documentation updated (if applicable)
  • No secrets or credentials committed

📓 Notes (optional)

Screenshots, design decisions, or additional context.

Admin UI Components:

  1. Regression Testing Dashboard - Visual test results with severity indicators
  2. Test Case Manager - Full CRUD operations with search/filter capabilities
  3. Batch Runner - Execute multiple test cases simultaneously
  4. Simulation Runner - What-if analysis with form inputs and results display

Testing Approach:

Comprehensive unit tests cover:

  • Test case CRUD operations
  • Batch test execution
  • Regression testing workflows
  • Mock data integration
  • Error handling and edge cases

Known Limitations:

  • Local testing was challenging due to Windows environment setup issues
  • Tests are validated and ready for CI/CD pipeline execution
  • Team members with working environments can validate functionality

All 6 issues resolved + dependency injection fix

Signed-off-by: hughhennelly <hughhennelly06@gmail.com>
- Add Sandbox sidebar tab and panel to admin.html with HTMX lazy-loading
- Add sandbox HTMX trigger in admin.js showTab() for revealed event
- Add /admin/sandbox/partial endpoint returning sandbox_partial.html
- Add /admin/sandbox/{simulate,test-cases,batch,regression}/partial endpoints
  for in-panel HTMX sub-page navigation
- Convert all sandbox navigation links from full-page <a href> to HTMX
  <button hx-get> targeting #sandbox-panel with innerHTML swap
- Convert Back to Dashboard links in sub-templates to HTMX buttons
- Fix route prefixes from /admin/admin/sandbox/ to /sandbox/ (within admin router)
- Fix template rendering to use request.app.state.templates instead of templates
- Fix settings references (ui_airgapped -> mcpgateway_ui_airgapped)
- Add required template context vars (max_name_length, gateway_tool_name_separator, etc.)

Known issue: Sandbox partial endpoints currently have auth commented out.
When AUTH_REQUIRED=true, HTMX requests from the admin UI return 401
because browser HTMX requests do not include auth credentials.
This needs to be addressed in a follow-up by either exempting sandbox
partials from auth or propagating session cookies to HTMX requests.

@crivetimihai I've pushed all review feedback fixes to my fork's issue-2226-clean branch (latest commit e159ab7). This addresses all 7 points from @brian-hussey's review:

✅ Database integration (PolicyDraft + SandboxTestSuite models, Alembic migration)
✅ PDP error handling
✅ Depends(get_current_user) on all mutation endpoints
✅ Input validation
✅ Dedicated sandbox docs page
✅ API docs with curl examples
✅ Alembic migration
✅ Tests expanded (admin UI, timeout, template rendering — 70 pass, 0 fail)
✅ All CI checks pass

I don't have push access to IBM's repo, so I can't update this PR branch directly. Could you pull my latest into this PR branch? Or would you prefer I open a new PR from my fork?
