While I personally am of the opinion of CI pulling in the external repo,
:gps and release folks want to vendor the tests in. This is because they do
not want our tree's open-ness to be dependent on an external service
(GitHub). But, like, I'm pretty sure GH's SLA is better our own...
Given that, here are the concrete next steps:
- Import test262 into m-c, keeping it up-to-date by periodic imports.
- Get a tier-2 test262 task (i.e. test262 failing does not close the tree)
and gather feedback about the update process/repo perf with the 20k extra
- If everything looks well, remove the tier-2 task and run test262 as part
of regular jstests.
