tests: increase the test coverage to 100% for analytics_routes, auth_routes, consultations_routes, consultation_quueue_routes

Increase Test Coverage for API Routes

Summary

The current API route test suite lacks sufficient coverage across several critical modules. This issue focuses on expanding test coverage to 100% for selected route files while ensuring all tests pass reliably without modifying existing business logic.

Problem Description

The following issues have been identified:

  • Low unit/integration test coverage in key API route modules:

    • api/v1/routes/analytics_routes.py
    • api/v1/routes/auth_routes.py
    • api/v1/routes/consultations_routes.py
    • api/v1/routes/consultation_queue_routes.py

  • Missing or incomplete test cases for:

    • Request validation (invalid payloads, missing fields)
    • Authentication and authorization flows
    • Error handling and HTTP status codes
    • Edge cases and boundary conditions

  • Potential gaps in:

    • Dependency overrides (e.g., database sessions, auth dependencies)
    • Mocking external services and async flows
    • Handling of exceptional scenarios

Objectives

  • Achieve 100% test coverage for the specified route modules

  • Ensure all existing and newly added tests pass successfully

  • Provide comprehensive validation of:

    • Successful API responses
    • Failure scenarios and error handling
    • Edge cases and invalid inputs
    • Authentication and authorization behavior

Proposed Solution

  • Write comprehensive tests using pytest and appropriate test clients (e.g., FastAPI TestClient)

  • Implement proper dependency overrides for testing:

    • Database sessions
    • Authentication mechanisms

  • Add test cases to cover:

    • All endpoints and HTTP methods
    • Conditional branches and logic paths
    • Exception handling scenarios

Scope

  • Add and enhance tests for:

    • analytics_routes.py
    • auth_routes.py
    • consultations_routes.py
    • consultation_queue_routes.py

  • Fix:

    • Incomplete or failing test cases
    • Missing mocks or incorrect setups
    • Gaps in edge case coverage

Acceptance Criteria

  • 100% test coverage achieved for all specified route modules
  • All tests pass without failures
  • No modifications made to production or business logic
  • All endpoints are fully tested, including success, failure, and edge cases
  • No runtime errors occur during test execution

Validation Steps

Run the following commands:

pytest -v
pytest --cov=app tests/
