title: How do I see the history of my Jenkins build test results?
body: <p>I've got a collection of Jenkins jobs which are all essentially tests packs - running lots of JUnit tests.</p>
  
  <p>I keep the results for 7 days and, with the aid of the <a href="https://wiki.jenkins-ci.org/display/JENKINS/Global+Build+Stats+Plugin" rel="nofollow">global build stats plugin</a> and <a href="https://wiki.jenkins-ci.org/display/JENKINS/build-metrics-plugin" rel="nofollow">build metrics plugin</a>, I can get a percentage of the number of builds (test packs) that had at least one failure in the last week.</p>
  
  <p>What I'm now interested in doing is getting the percentage of all test failures over one week, to get a better idea as to how badly the set of builds failed - was it just one test that caused each build to fail? Or all the tests?. Is it possible with an existing plugin?</p>
  
  <p>I know the data is there because the home page of any of my jobs has a graph on the right where the green area represents test passes and red fails, for all of the previous builds. This gives me some idea, but I'd like a figure to report with.</p>
