The point of my test is that it'd get only 2 possible answers, 1 and 0. (If 
there are other exit codes, append an || false and it'll be only 1 and 0.) 
So you take a screenshot of the console output and it will be one of 2 
canned screenshots, where the one with 0 will be marked as known pass and 
the one with 1 as known fail. But of course, if the screenshot only shows 
"1", you have no idea what the error actually was.
