title: Should I use PHPUnit in a staging/production environment?
body: <p>I have installed the PHPUnit framework to perform unit testing. I have written the test cases and also used the existing PHPUnit libraries for my testing.</p>
  
  <p>Is it necessary to configure the PHPUnit framework in staging and production environment? If so, the phpunit test framework and the related files took memory in staging and production which is unnecessary.</p>
  
  <p>Is it enough to use the PHPUnit testing framework in local environment?</p>
