fix: Dev v3 to main

[NirajC-Microsoft]

Purpose

This pull request primarily refactors import paths throughout the test suite to use explicit, absolute imports from the src.backend and src.mcp_server packages. This change improves code clarity, maintainability, and consistency as the project structure evolves. Additionally, the test workflow configuration is updated to ignore more test files during coverage runs, streamlining CI behavior.

Test workflow improvements

• Updated the .github/workflows/test.yml workflow to ignore additional test files during coverage runs, reducing unnecessary coverage reporting and focusing on relevant tests.

Refactoring import paths in backend tests

• Changed imports in backend test files (such as test_auth_utils.py, test_sample_user.py, test_health_check.py, test_messages.py, test_config.py, and test_otlp_tracing.py) to use explicit paths from the src.backend package, improving clarity and consistency. [1] [2] [3] [4] [5] [6]

Refactoring import paths in mcp_server and agent tests

• Updated imports in agent and mcp_server related test files (test_foundry_integration.py, test_factory.py, test_hr_service.py, and test_utils.py) to use absolute paths from src.backend.v3.magentic_agents and src.mcp_server, ensuring proper module resolution. [1] [2] [3] [4]
