Test Suite

Test Status Code Input and Output
1   Pass
filetext = fileread('summ.m'); assert(isempty(strfind(filetext, 'regexp')),'regexp hacks are forbidden')

2   Fail
v = randi(10, 1, randi(10)); s = summ(v); assert(length(s) == length(v) - 1)

Error using vertcat Dimensions of arrays being concatenated are not consistent. Error in summ (line 2) s = [0; v(2:end-1); 0] + [v(:)]; Error in Test2 (line 2) s = summ(v);

3   Fail
v = 1:10; s_correct = 3:2:19; assert(isequal(summ(v),s_correct))

Error using vertcat Dimensions of arrays being concatenated are not consistent. Error in summ (line 2) s = [0; v(2:end-1); 0] + [v(:)]; Error in Test3 (line 3) assert(isequal(summ(v),s_correct))

4   Fail

Assertion failed.
