I suggest naming these like inlined accessors as well, e.g. "scheme_range()",
and omitting the blank lines between them.

[Peter Kasting, 2017/03/01 02:39:10]

That doesn't sound right.  CurrentTextIsURL() ought to be false for this,
leading us to emphasize the whole string (rather than a range that includes the
whole string), I'd think.

[elawrence, 2017/03/01 21:49:01]

The problem is that OmniboxEditModel::CurrentTextIsURL() returns true if
(!user_input_in_progress_). CurrentTextIsURL() isn't virtual, and even if I
expose tweak the TestingOmniboxEditController so that calling SetInputInProgress
doesn't crash, CurrentTextIsURL ends up crashing inside a call to
TemplateURLService::Load from KeywordProvider::GetTemplateURLService.

For now, I've just removed this test.

[Peter Kasting, 2017/03/01 23:18:47]

That's because you're calling SetText() in all of these, which is really a
low-level Textfield function rather than an OmniboxView one.  I would attempt to
use omnibox_view()->SetUserText() instead, which is the intended API to change
the text in this control.  That's a suggestion not just for this test, but all
the ones above.

This may still cause problems if this test doesn't instantiate enough objects
(as mocks/fakes) to avoid crashing today.  My hope is that this would be fairly
easily solved, especially since the test base is already instantiating a
TestingProfile and such.

[elawrence, 2017/03/01 23:50:53]

Yes, SetUserText() code path that leads to the described crashes. I didn't spend
a lot of time looking into how to make the TemplateURLService call not crash,
but it doesn't seem like the OmniBoxEditController is well set up for
unittesting today, and it's not clear that a security fix should block on an
broader rearchitecture. 

[elawrence, 2017/03/02 19:08:01]

Exposing CurrentTextIsURL as a virtual function on the View and checking that is
the only reasonable path I've found for unblocking the unit test.
