1.2 Lab work this week

3 From the Classroom Whiteboard/Chalkboard

I took a structured approach which involved setting up test cases. I went on the assumption of having no knowledge of permissions - blackbox testing in essence. Basically, I started by giving full permissions for USER to “target directory”, “source directory” and “source file”. As per #1, #2 and #3, I started by removing all permissions on the “target directory”; then set bits, one-by-one with chmod command. On success, I recorded symbolic permissions; then moved on to the “source directory” and repeated process. On success, I recorded symbolic permissions; then moved on to the “source file”. It took me 48 test cases to ‘proof’ the entire exercise. I think the total possible of cases could have been (2^3) x # of boxes (16) = 128; but you stop on success. I recorded my results in a document which is attached. C. Dougan

(The number of cases is actually 2^3^# where # is the number of boxes in a row. Rows with three boxes have 8x8x8=512 possible combinations, but careful choosing of test cases can quickly reduce that. -Ian!)
