/**
 * The JUnit xml output desired by Jenkins essentially looks like this:

 * testsuites:
 *   - testsuite: (name, timestamp, hostname, tests, failures, errors, time)
 *     - testcase: (error or failure, name, classname, time)
 *
 * Full XSD avaliable [here](http://windyroad.com.au/dl/Open%20Source/JUnit.xsd)
 *
 * from
 *
 * {
 *   stats: {
 *
 *   }
 *   suite: [
 *     {
 *       name:
 *       results: []
 *       suites: [] // optional
