% Test formula to calculate the average speed given distance traveled and
% time required

%%%%%%%%%%%%%%%%%%%%%%%%
% define the tolerance %
%%%%%%%%%%%%%%%%%%%%%%%%

% tolerance is "how far away from the expected value" the result
% is allowed to be.  Since the calculation involves basic integer
% operation results can be reasonalbly precise

tolerance = 0.0001;

%%%%%%%%%%%%%%%%%
% Run the tests %

% Test 1

  % signal that test failed, and print both expected and actual
  disp('test 2 failed');
