Added Nick Becker's Testing 1, 2, 3 Assignment

Adding 3 test file for the "Testing" assignment. Will add the test_html_render when I have the final word on what exactly is needed. 
Lines 9 - 13 could be condensed into a `for` loop since a `for` loop implicitly calls `.next()` on the collection it's iterating over. With a `for` loop, tuple assignment, and `zip()`, you can write this test in about three lines.
