title: Combining robot framework test reports
body: <p>We run the robot framework test cases in a certain order and generate a separate output files for each collection. Example is shown below:</p>
  
  <p>pabot -L TRACE --output test1.xml robot_framework/tests/test1</p>
  
  <p>pabot -L TRACE --output test2.xml robot_framework/tests/test2</p>
  
  <p>Later on we use 'rebot' command to combine the test reports as shown below:</p>
  
  <p>rebot test1.xml test2.xml.</p>
  
  <p>The issue we are facing is, there is no output.xml file generated. How can we combine the reports such that there is a 'output.xml' file? If we do not have this file, the Jenkins plugin for Robot Framework fails to generate report.</p>
