//    FILE: unit_test_001.cpp
//  AUTHOR: Rob Tillaart
// VERSION: 0.1.0
//    DATE: 2021-09-25
// PURPOSE: unit tests for the SHT2x temperature and humidity sensor
//          https://github.com/RobTillaart/SHT2x
//          https://www.adafruit.com/product/2857

//

// supported assertions
// ----------------------------
// assertEqual(expected, actual)
// assertNotEqual(expected, actual)
// assertLess(expected, actual)
// assertMore(expected, actual)
// assertLessOrEqual(expected, actual)
// assertMoreOrEqual(expected, actual)
// assertTrue(actual)
// assertFalse(actual)
// assertNull(actual)
// assertEqualFloat(expected, actual, epsilon);    // fabs(a - b) <= epsilon

/*
  most unit tests will test for fail 
  as there is no sensor connected
  and there is no mockup.
  
  It appears that Wire.write does not fail without sensor...
