Test Coverage Improvements (>95%) & CI Coverage Fix

[Ayesha-Anwar607]

What was changed?

1. Fixed 0% Coverage Reporting in CI Workflow (.github/workflows/ci.yml):

   • Updated dependency installation to run pip install -e . (editable mode) and set PYTHONPATH=..
   • Previously, coverage.py was checking local files while tests executed against installed site-packages, resulting in an artificial 0% report. Coverage reporting in CI now correctly tracks the source files.

2. Added New Unit Tests (tests/):

   • tests/test_provider_methods.py: Added coverage for all FakerPKProvider methods when generating multiple outputs (count > 1) and added error handling assertions for invalid inputs (e.g. pytest.raises(ValueError) for invalid industry names).
   • tests/test_student_profile_gender_cnic_alignment.py: Verified CNIC gender digit alignment (odd for male, even for female).
   • tests/test_student_profile_multiple_count.py: Validated list generation structure for student profiles.

Results

• All Tests Passing: 42/42 tests passing.
• Code Coverage: Increased total code coverage from 86% to >95% (exceeding the required >90% threshold).

Great addition. The implementation is clear, and the accompanying tests provide good confidence. LGTM
