Scenario Status

• an icon showing whether the test fails or passes and whether it's reliable or not.
  The legend for this icon is:
  • Green (): mark a successful result, which means this test has neither significant performance regression nor significant standard error
  • Red (): mark a failing result, which means this test shows a significant performance regression (more than 10%)
  • Gray (): mark a failing result (see above) with a comment explaining this degradation.
  • Yellow ( or ): mark a failing or successful result with a significant standard error (more than 3%)
  • Black (): mark an undefined result, which means that deviation on this test is not a number (NaN) or is infinite (happens when the reference value is equals to 0!)
  • "n/a": mark a test for with no performance results
• the value of the deviation from the baseline as a percentage (ie. formula is: (build_test_time - baseline_test_time) / baseline_test_time)
• the value of the standard error of this deviation as a percentage (ie. formula is: sqrt(build_test_stddev^2 / N + baseline_test_stddev^2 / N) / baseline_test_time)
  When test only has one measure, the standard error cannot be computed and is replaced with a '[n/a]'.
