python: Add a serve-wpt command to mach

[emilio]

r? @frewsxcv

[emilio]

By the way, doing things this way (or using ./serve directly), there's a syntax error in testharnessreport.js, do you know how it can be worked around @frewsxcv?

I tried running this:

coreyf@frewbook-pro ~/D/r/servo ((18f4846...))> ./mach serve-wpt

It occurs when you don't have the domains in the hosts file. Maybe it should be mentioned somewhere. I guess the testsuite makes use of the default hosts file, unlike wptrunner.

[jdm]

We should set our environment variable to get the proper host replacements.

[emilio]

I don't seem to find a cross-platform way to override the hosts file... Should I dive in serve.py and do whatever wptrunner is doing?

[Ms2ger]

It seems better to implement this as part of test-wpt.

[metajack]

@Ms2ger Are you suggesting that test-wpt get a --serve option?

[Ms2ger]

Yes, I think that would be easiest

Closing due to inactivity.
