Automatic testing is critical to developing a robust, scalable application. Developing a test suite can seem
daunting at first, but it's worth doing. The first test is the hardest. Once you've set up your test framework and
written your first test, subsequent tests will flow much more easily. Just as you can improve a site linearly
through small, automatic refactorings that add up over time, so too can you improve your test suite by adding
just a few tests a week. Sooner than you know, you'll have a solid test suite that helps to ensure reliability by
telling you when things are broken and showing you what to fix.
