title: Any rules of thumb for estimation of UAT effort - like for number of scripts as compared to the number of business requirements?
body: <p>I'm attempting to estimate the number or testers required to test out a project.  One method is to determine the number of scripts that will be required and was wondering if there was a rule of thumb for number of scripts as compare to number of requirements.
  I'm estimating 2 - 3.</p>
  
  <ul>
  <li>1 for a sunny day type test</li>
  <li>1 for a negative test</li>
  <li>1 for at least combining 1 requirement test with at least one other.</li>
  </ul>
  
  <p>but that's just my initial guess.  If there are some best practices, I'm all ears.
  Again, this is not for unit testing or systems testing, this is for user acceptance testing.</p>
