Note: The REQ-172 document states 82.58% line coverage, but actual measurement shows 76.83%. This discrepancy may be due to:

  • Different test execution scope (library vs integration tests)
  • Code changes since last measurement
  • Different coverage tool configuration

Test Statistics​

  • Total Tests: 1,086 passed
