Nit: EXPECT_EQ(input[1], output[1].url)?  (2 places)

Done, but I don't see another place this could apply. (Note that the other two
values being checked here are NOT the same as their corresponding values in
input--we are explicitly checking that they were transformed as desired.)

Nit: You put a blank line below this in the above cases, be consistent
