WebSpeech: plumb through a method to generate fake speech jobs for testing

[chris fleizach]

We need to be able to tell DRT that we want to send fake speech jobs, then get the system to essentially fake up the speech job. we don't want real speech jobs to be sent lest they cause strange output on a persons system who's running layout tests

Adam and Dominic, what do you think of this approach to fake the speech synthesis output?

The idea is have a WebCore::Settings() method that can be checked, and then the platform can do something to fake the simulation that the speaking job completed

This isn't a very appealing approach to mocking out speak synthesis.  It's generally better to cleanly separate mock code from production code.  Ideally the mock code isn't linked into the production binary at all.  In other places, we've mocked out subsystems at the Platform API boundary, but I understand that might not work well for ports like apple-mac that interact directly with the underlying operating system.

Do you think I should do something like

MockPagePopup, (where we have a MockPlatformSynthesizer)

and then it's enabled through an Internals setting like
   void setEnableMockPagePopup(in boolean enabled) raises(DOMException);

[Adam Barth]

Is the mock linked into the production binary?  I'd much prefer not to link it into the production binary.

That one specifically is, but I see other Mocks*, like MockCDM that is only linked in WebCoreTestSupport, so perhaps I can do that as well

[Adam Barth]

If we can link it into WebCoreTestSupport, that's likely to be better.

New patch uses a method in Internals to modify enter testing mode.

Doing that will create a mock platform synthesizer. This mock synthesizer lives only in WebCoreSupport.

RefPtr -> why not OwnPtr?

The general approach looks fine, but you've only modified one of the N build systems used by WebKit.

Thanks for your feedback. 
Didn't want to do to most painful part of adding new files unless it looked like a good approach

[Adam Barth]

Yeah, this isn't the best design for ports that have a Platform API, but this is fine for ports like apple-mac that talk to the operating system directly.
