title: robotframework data-driven tests using external data source
body: <p>How to create a data-driven test using robotframework based on the following:
  
  <li>test data are stored in a separate text file.
  <li>the test data file contains test data for multiple testsuites.
  <li>common keywords are store in a resource file.</p>
  
  <p>This is my first time to create a data-driven test using robotframework, I have no clue how to do it. I've read robotframework documentations but none of it give a clear explanation on how to do it.</p>
  
  <p>Thanks...</p>
