Comparing tests in SpeedCurve

Since there is no UI way of comparing two tests within SpeedCurve (not yet anyway), I thought I'd share a quick tip of how to compare two tests against each other.

Content:

Get two test ids

Let's find two tests we want to compare, for this example I'm using a site (Le Monde) found in the newly released benchmark section of SpeedCurve.

Yeah, there's a spike there we should compare, so click on the lowest point (Sun 23 Feb) and grab the id part that's available if you right click on the View Test link and click on Copy Link Address.

low-point

Now do the exact same thing for the higher point:

high-point

Deploy view

It's in the deploy view where the magic happens, right click on Synthetic - Deploy and grab the base url:

deploy-view

Now use the ids like this: deploy/?previous=(id1)&latest=(id2)

Compare url


Result

Pasting the url in the browser takes you to the deploy site where you now have access to the filmstrip / video comparison of the two tests and the nitty gritty WebPageTest data

result

Visit the compare page yourself to figure out what that spike was all about!
