FTEST: Octave function test routine

Paul Kienzle ()

Octave codes

Abstract: I wrote ftest, which extracts lines starting with ##! and evaluates them with eval(). It doesn't cope with syntax errors elegantly. E.g., usage: r = mod(x,y) Compute modulo function, handling negative number correctly; i.e., mod(-1,3) is 2, not -1 as rem(-1,3) returns. function r=mod(x,y) if nargin != 2, usage("r=mod(x,y)"); endif r = x - floor(x./y).*y; endfunction ! if mod(5,3) != 2, disp("mod fails for positive a"); endif ! if mod(-5,3) != 1, disp("mod fails for negative a"); endif ! if mod(0,3) != 0, disp("mod fails for a=0"); endif ! if !isempty(mod([],[])), disp("mod fails for empty"); endif ! if any(mod([-5 5 0],[3 3 3]) != [1 2 0]), ! disp("mod fails for columns"); endif ! if any(mod([-5 5 0]',[3 3 3]') != [1 2 0]'), ! disp("mod fails for rows"); endif ! if any(any(mod([-5 5; 0 3],[3 3 ; 3 1]) != [1 2 ; 0 0])), ! disp("mod fails for matrices"); endif
