Sample Test Scenarios - Test Report Summary

Current Weather Data API - Test Suite
Basic Shakedown Tests
  √ Verify 'Current Weather By GPS Coordinates' Api response is OK (1157ms)
Functional (Data-Driven) Tests
  √ Verify STATE CODE is displayed in response of 'Current Weather By GPS Coordinates' Api (1120ms)

Forecast Weather Data API - Test Suite
Basic Shakedown Tests
  √ Verify 'Forecast - 3 Hourly Data' Api response is OK
Functional (Data-Driven) Tests
