Good Coverage (70-90%)

Module Coverage Statements Reason
layer_parameters.py 86% 93/108 Existing tests
fourier_maps.py 83% 226/272 Existing + new tests
ionospheric_profile.py 73% 237/325 Existing tests
__init__.py 70% 28/40 Existing tests

Needs Coverage (<70%)

Module Coverage Statements Priority
path_geometry.py 57% 104/181 P2
muf_calculator.py 24% 41/174 P1
reflectrix.py 9% 23/270 P1
prediction_engine.py 0% 0/674 P1
space_weather_sources.py 0% 0/289 P4

📈 Progress Toward >70% Coverage Goal

Current Status: 44% → Target: 70%

Gap Analysis:

  • Current: 1,258 statements covered
  • Target (70%): 1,994 statements needed
  • Additional coverage needed: 736 statements

Path to 70%:

  1. Add prediction_engine tests (674 statements) → Would bring total to ~68%
  2. Add basic reflectrix tests (100-150 statements) → Would exceed 70%

Estimated Effort:

  • Prediction engine tests: 8-12 hours (complex module)
  • Reflectrix tests: 4-6 hours (raytracing logic)
  • Total: 12-18 hours to reach 70% coverage
