title: Different Types of Testing (eg. Unit, Functional, Integration, etc.) Document
body: <p>A few years ago I saw this great (PDF) document from Google.  The document explained, in a single page, what all the various types of software testing mean (eg. what separates a functional test from an integration test from a unit test from a ...).  It was a very handy reference, but of course I didn't save a link to it, and now I can't find it when I google for it (oh the irony of not being able to google a Google document).</p>
  
  <p>Now I know there are great SO answers for exactly this question, but I was specifically looking for a single-page, print-formatted guide that I could hang in the office, rather than an SO answer.</p>
  
  <p>Can anyone point me to either the Google document I'm thinking of, or any other good single-page breakdown of software testing types?</p>
