title: Jenkins Test Result Trend Graph Empty, but Tests Are Run
body: <p>Where does the data that produces the "Test Result Trend" graph actually come from?  I have a "Test Only" job that produces 2 files in target/surefire-reports. (Produced by maven)  Inspecting the files directly shows that the tests are executing and passing.</p>
  
  <p>The graph shows successful builds along x-axis but no test results.  If I click on a specific build from the project page, it shows "(no tests)" next to the "Test Result" link.</p>
  
  <p>Is there some sort of post-processing I need to do on the XML files?  They are in JUnit format, produced by the maven-soapui-plugin.</p>
  
  <p>Thanks!</p>
