"""Unit tests for DashboardHTTPService component.

Tests verify HTTP service extends BlackboardHTTPService, mounts WebSocket endpoint,
serves static files, and integrates with orchestrator.serve(dashboard=True).

COMPREHENSIVE API ENDPOINT TESTS:
===============================

This file has been expanded to boost coverage from 39.29% to 80%+ by adding comprehensive
tests for all previously untested API endpoints:

/api/artifact-types (GET) - Lines 170-181 in service.py
/api/agents (GET) - Lines 199-210
/api/control/publish (POST) - Lines 247-300
/api/control/invoke (POST) - Lines 319-376
/api/themes (GET) - Lines 449-493
/api/control/pause (POST) - Line 501 response
/api/control/resume (POST) - Line 501 response
/api/version (GET) - Lines 212-228
/api/streaming-history/{agent_name} (GET) - Lines 396-431

TESTING APPROACH:
- Use pytest and httpx for FastAPI endpoint testing
- Mock orchestrator, type_registry, and external dependencies
- Test both success paths and error conditions (400, 404, 422, 500 responses)
- Test request body validation and edge cases
- Use proper JSON serialization testing
- Test correlation ID generation and timestamp formatting
- Test Pydantic validation errors properly
