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. 
This function returns after the first iteration in this `for` loop. None of the below `assert` statements occur. What was the intent of lines 7 and 8?

These tests don't "fail" because the `assert` statements are never reached.
