### Test Suite

Test Status Code Input and Output
1   Pass
fileID = fopen('SINE.m','w'); fprintf(fileID,'function s = SINE(angle)\n'); fprintf(fileID,' s = sind(angle);\n'); fprintf(fileID,' pause(0.012);\n'); fclose(fileID); status_correct = 'fail'; status = 'pass'; try testSuite() catch e status = 'fail' assert( isequal(e.message, 'Too slow') , 'Wrong message' ) end assert( isequal(status, status_correct) , 'Wrong status' )

status = 'fail'

2   Pass

status = 'fail' ans = 'Banned word'

3   Pass
fileID = fopen('SINE.m','w'); fprintf(fileID,'function s = SINE(angle)\n'); fprintf(fileID,' % This is a simple problem: the answer only takes one line!\n'); fprintf(fileID,' s = sind(angle);\n'); fclose(fileID); status_correct = 'pass'; status = 'pass'; try testSuite() catch e status = 'fail' end assert( isequal(status, status_correct) , 'Wrong status' )

4   Pass

6   Pass
% NOTE: You may notice that the user function has been named "SINE", % in uppercase. That is an extra precaution to avoid accidentally % triggering an error due to a banned 'word' (sequence of characters). % Careful choice of code to check for banned _functions_ is better! assessFunctionAbsence('sind', 'FileName','testSuite.m') assessFunctionAbsence('sin', 'FileName','testSuite.m') assessFunctionAbsence('cscd', 'FileName','testSuite.m') assessFunctionAbsence('cosd', 'FileName','testSuite.m')
