I want to add another test here that tests that the report actually gets sent.
My plan was that I would create a TestURLRequestContext that overrides
GetURLRequest to return a TestURLRequest that asserts that the upload data is as
expected, but that would require making URLRequestContext::GetURLRequest virtual
-- would that be okay?

[Ryan Sleevi, 2015/03/06 19:32:31]

Testing the data is as expected is testing the implementation, not the
interface; I wouldn't recommend that.

mmenke@ will know whatever the "Right Way" to test this interface would be; I
can never keep all our testing straight.
