It looks like TopSitesFactory::BuildInstanceForProfile() has the same
implementation, and since TopSitesFactory does not overrides
ServiceIsNULLForTesting() then I think the default implementation of
TopSitesFactory::GetForProfile() will work with a TestingProfile. This means
that you could just remove this method and TestingProfile::CreateTopSites().

Can you try to change TestingProfile::CreateTopSites() to do nothing (i.e. has a
{} implementation) and see if all unit and browser tests pass? I think they
should, in which case you can simplify this file.

[sdefresne, 2015/01/14 21:31:47]

Please also test keeping TestingProfile::CreateTopSites() and overriding
TopSitesFactory::ServiceIsNULLForTesting() to return true.
