Your task is to add the missing code in an EllipticalMachine class and its corresponding JUnit test class EllipticalMachineTest , based on the PEKKO IoT tutorial example we saw in class.
You will implement the following messages in the EllipticalMachine class.
- RecordWeightInKgAndResistanceLevel. Record the weight of the user, and the resistance level chosen, i.e., 100 kg, level 2.
- CalculateCaloriesBurned. Calculate calories burned per minute using the following formula: Calories burned per minute = (MET * body weight in Kg * 3.5) ÷ 200. Where “MET'' is a measurement of the energy cost of physical activity for a period of time. You can find an activity’s MET on the table below.
Type of activity | MET |
Resistance level 2, light effort | 4.6 |
Resistance level 5, moderate effort | 4.9 |
Resistance level 8. vigorous effort | 5.7 |
For example, Calories burned per minute = (4.6 * 100 * 3.5) ÷ 200
=8.049999999999999 (using Java Double precision).
Your test scenario:
- Record the following weight and temperature: 100 Kg., resistance level 2 and calculating the calories burned. Add the missing code in EllipticalMachineTest class, specifically inside the method called "testReplyWithCaloriesBurnedPerMinute"
Expected result:
