My question is this,
I have gotten the assignment I am attaching below all done, it is graded by webcat, an automated grading website for students that tests my code against the one provided by the instructor along with the drivers. However, I am getting the message that my code coverage is 100% but it is not giving all the grade for some reason with no explanation. Ususally you get at least a message saying why you are not getting the grade. Is my testing not extensive enough or something, I just don't get it. So, if there is an expert here who can help, I would really appreciate it.
