const method?

You can also return an AssertionResult here. E.g. |AssertionResult
VerifyIDNDecoded()| and then do EXPECT_TRUE(VerifyIDNDecoded()).

Done.

[estark, 2015/03/25 00:45:25]

Done.

(Question: is the purpose of returning an AssertionResult to make the test
output more readable?)

[meacer, 2015/03/25 01:08:39]

In this case, yes I think it's slight more readable. General usage is when you
expect to do different types of assertions based on a value passed to the
function. So you could have something like this:

AssertionResult TestEven(int i) {
  return i % 2 == 0 ? AssertionSuccess() : AssertionFailure();
}

EXPECT_FALSE(TestEven(1));
EXPECT_TRUE(TestEven(2));

Makes sense, thanks!
