title: Unit Testing php application (What should I stress test?)
body: <p>I am currently writing the unit tests for a php data access object. Obviously I should stress test the server environment at or above expected traffic levels, but as was answered to this question: <a href="https://stackoverflow.com/questions/3437655/should-unit-tests-cover-stress-testing">Should unit tests cover stress testing?</a> there are some cases where you should stress test the code itself.</p>
  
  <p>My question is this: Should I include stress tests in my Unit Test and why or why not? I'm still fairly new to both unit testing and php, so I need to build up a firmer grasp of what sort of tests are recommended in which situations.</p>
