Spring Circular Dependencies

I know you've been there, like me:

We know it's unhealthy to compare yourself to others.

In particular since it is the time for new year's resolutions and this looks like a good candidate.

There's even a famous quote that states:

But sadly, tests results in OctoPerf won't get this chance. Now you can compare up to 4 test results in OctoPerf! We've also improved our UI again to make a better use of the space available.
