14. What is the difference between a test stub and a test driver?

What's the main difference between testing and debugging when it comes to a computer program?

Data Generator Most application depends on data. In IoT data is collected/generate by sensors. Since, we do not have access to sensors, we will have to generate data via code. The plotting a sufficient number of these data points (500 in this case) should get the following diagram or something very similar:   You will pick a quantity that you would like to simulate (such as temperature, humidity, barometric pressure, customers arriving at a mall, or just with an alternate descriptor) and decide what shape you will emulate.  This will guide you in selecting sensible value base lines for your data values. e.g., If you pick inside temperature then normal range will be 18-21oC. Design and build a class that will model your sensor reasonably well.  Notice how the peaks do not occur at regular interval, nor are they the same height. Even the squiggles are the same shapes. You will create a class with a single public member (property) that give you a “random” value in your intended range and…
