Hoping to take a look at this within RelEng as new owners for our next sprint!

Hi @Krinkle. Can you provide a fleshed out example of what you want the new output to look like?

@Krinkle any strong opinions on what new output should look like?

Scenario's are configured like this in .fresnel.yml:

runs: 7
scenarios:
  View history of a page:
    url: "{MW_SERVER}{MW_SCRIPT_PATH}/index.php?action=history"
    viewport:
      width: 1100
      height: 700
    reports:
      - navtiming
      - paint
      - transfer
    probes:
      - screenshot
      - trace

I suppose the idea would be to print this information during the record step. Right now, recording prints 1 line for each run, stating the scenario label and the run number, followed by what the recording does (usually, 1 navigation, and then collecting metrics).

You could e.g. print the scenario options in full, right before the first run or something like that.

Change 1003455 had a related patch set uploaded (by Thcipriani; author: Thcipriani):
