1506352 - Stop running web-platform-tests in jstests.py until we have a working strategy for updates

Status: RESOLVED FIXED

(Core :: JavaScript Engine, enhancement)

Description

[James Graham [:jgraham]]

We started running some wasm tests from web-platform-tests in the jsshell in Bug 1333800. However we didn't properly consider how things would work when the tests are updated; a wpt update introducing a test that doesn't pass currently breask the build. There are two things that would help:

* Start producing a wptreport.json log and run the jsshell tests as part of the wpt update process, so we are able to update the metadata to match the observed failures on import.

* Don't run the jsshell tests as part of the build, but as a seperate job. IN particular make the wpt part of this tier 2 so that failures can be fixed asynchronously rather than requiring a backout.

Before we can do one or both of those things we need to reconsider running these tests by default.

I wonder if it's possible to just pass the formatter in here rather than have the handler abstraction, but I don't have a strong opinion.

nit: Can you explicit `wptreport` into `a Web Platform test report`, so there's no doubt for people who read this for the first time?

Check with `is not None`, to avoid surprising results?

ditto?
