1.0 INTRODUCTION
The purpose of this document is to provide a comprehensive test plan for the device we
have built which we call the “Cooling Solution for Adjustable Resistance Bike Trainer”.

3.0 PRETEST PREPARATION
3.1 Test Equipment Needed
 Digital Multimeter
 Oscilloscope
 Laptop PC
 Laboratory DC Power Supply
4.0 SYSTEM TESTS
4.1 Unit Testing
 Hall Effect Sensor

Potentiometer

Fan
Measures movement of bike wheels
Calculation is used to estimate RPM of bike
Measures resistance that the bike trainer applies to the
wheels.
Fan speed approximates level of work output by rider by
combining and scaling RPM and Resistance inputs
4.2 Integration Testing
 Different speeds with Pot Constant

Approx. same speed with changing pot
4.3 Functional Testing
 Full system testing
4.4 Stress Testing
 Random Testing
Test Plan
Biker raises and lowers RPM, fan
speed should raise and lower
accordingly
Biker attempts to maintain constant
speed while resistance is increased
and decreased, fan speed should
correspond directly to pot position
Biker increases speed, then decreases, simultaneously the
pot decreases, then increases, fan speed should vary little.
Biker is given free rein to increase and decrease speed,
while pot is modulated randomly, and fan should function
appropriately
