If he doesn't want to fix the line breaks so that those assertions are on one line, then he doesn't have to, but I think that it's a perfect example of when _not_ to stick to 80 characters - especially when not putting the line break in there puts the lines at only 81 or 82 characters long. In general, unit tests are definitely cleaner when assertions take up only one line each - either by actually using more than 80 characters or by doing stuff with variables or aliases to make the code short enough to fit reasonably.
