  Calculate kWh
    1) should return 1 when consuming 1000W for 1 hour
    2) should return 0.5 when consuming 1000W for 30min

  IsNightTarif
    3) should return true for night hours
    4) should return false for day hours
    ✓ should return true for weekends
    ✓ should also work when we pass integers instead of date objects
