Not much time left in the summer

My two-month stay on campus for the summer has less than two weeks left. Before I leave, I want to get an early but usable version of my project out for testing. The sub-project of writing the assignment's test suites is almost half done. If I can keep up the pace, all the tests should be finished before the end of July. My full-time appointment continues until the Saturday before classes start, so that's three weeks working from home. During that time, other course staff will be testing the assignment; I'll be tweaking it based on their feedback and working on a system to make sure students who fall behind aren't completely sunk.
