Resolve "Full coverage for role_request, user, sms services"
Merge Request
Overview: This MR focuses on improving test coverage for key service-layer modules by adding comprehensive unit tests. The goal is to ensure reliability, correctness, and maintainability of business logic across critical components such as role requests, SMS handling, and user management.
What does this MR do and why?
This MR improves the existing unit tests for the following service files to 100% :
- role_request_service.py
- sms_service.py
- user_service.py
Changes Made:
Added missing unit tests for:
- app/services/role_request_service.py (≈81% coverage)
- app/services/sms_service.py (≈86% coverage)
- app/services/user_service.py (≈83% coverage)
Covered:
- Business logic validation
- Conditional branches
- Exception handling
- Edge cases
Technical Details
- Used coverage report to identify uncovered lines
- Added tests for all if/else branches
- Triggered exception paths using mocks
- Covered edge cases (null, empty, invalid inputs)
- Ensured no changes to service logic
Flow: Tests → Mock dependencies → Execute service → Validate outputs and exceptions
Type of Change:
-
🐛 Bug fix (non-breaking change that fixes an issue) -
✨ New feature (non-breaking change that adds functionality) -
💥 Breaking change (fix or feature that would cause existing functionality to change) -

Before - These 3 files had a coverage from 81 - 86 %
After covering of missing files the test coverage is 100%
How to Validate Locally:
Steps to Validate:
Run the test suite with coverage - uv run pytest --cov=app tests/
Verify test results: Confirm coverage is generated for: app/services/role_request_service.py app/services/sms_service.py app/services/user_service.py
