 * Such information is used on:
 * TestSequencer.sort(tests: Array<Test>)

 *
 * After the results are collected,
 * TestSequencer.cacheResults(tests: Array<Test>, results: AggregatedResult)

   * -> Has it failed during the last run ?
   * Since it's important to provide the most expected feedback as quickly
   * as possible.
   * -> How long it took to run ?
   * Because running long tests first is an effort to minimize worker idle
   * time at the end of a long test run.
   * And if that information is not available they are sorted based on file size
   * since big test files usually take longer to complete.
   *
   * Note that a possible improvement would be to analyse other information
   * from the file other than its size.
