@thakis, any advice on how to go about this? I did some code searches but was unable to figure out which bots build with is_official_build = true and where their scripts for running unit tests live. Thanks for any pointers.

I just saw this request; doing an official build takes a lot of time, because it enables LTCG/WPO. Maybe you want these to run on the official builds? Michael is working on this.

SwiftShader's unit tests don't depend on chrome (just gtest) and they're very small, so they don't take a lot of time to build.

Ah then you could add a separate builder, similar to whatever release you use but in addition with is_official_build=true to get this coverage.

That is precisely what we could use some guidance on. Where do I add such a builder?

Is this still a need? cc'ing John as I'm not familiar with the CI system anymore.

Yes, this would still be good to have.

https://www.chromium.org/developers/testing/adding-tests-to-the-main-waterfall seems out of date.

Yes, yes it is :).

You're better off starting with the instructions in //testing/buildbot/README.md at this point, and then asking jbudorick@ or martiniss@ or kbr@ or myself (or, failing all of those things, asking on chromium-dev) if you have questions.

Thanks for the pointers!
