run-perf-tests results page should not display the result value if a test was failed. It would be good to indicate FAILED instead of the result.
I don't think it does... when a test fails, JSON wouldn't have an entry for that test.
I still don't understand this bug.
The problem was that even a test was failed it showed a very small value for the runtime and delegated it onto the chart. I'm going to reproduce it at home and put the output here.
I can not reproduce it anymore. Probably it was just something related to the environment of my old workstation. Closing this as invalid.
