What are test beds and how to write test beds in your coursework?

Test beds in software based assignments are used to test the modules and blocks of code like a function , a class.

Example:

Here there is a function written in C++ to calculate the values of resistances R1 and R2.

Source Code in C++

void tee_type_attenuator()

{

char color;

float attenuation, impedance, voltage,r1,r2;

cout<<“Thank you for using tee_type_attenuator”;

cout<<“please enter the attenuation in decibels\n”;

cin>>attenuation;

cout<<“please enter the impedance\n”;

cin>>impedance;

voltage= pow (10,-impedance/20);

r1=impedance*(1-voltage)/(1+voltage);

r2=(pow(impedance,2)-pow (r1,2))/(2*r1);

cout<<“The resistor value of R1 is”<<r1;

cout<<“The resistor value of R2 is”<<r2;

color=calculate_color_code(r1);

cout<<“The value of R1 is”<<r1<<“and its color code is”<<color;

color=calculate_color_code(r2);

cout<<“The value of R2 is”<<r2<<“and its color code is”<<color;
