May want to also test separately that the same key is never equal to itself

EXPECT_FALSE(key1 < key1);
EXPECT_FALSE(key2 < key2);

[Ryan Sleevi, 2016/05/18 02:02:02]

Did you mean to say "never equal"? Or did you mean to say "Always equal"?

[eroman, 2016/05/18 02:06:43]

See the code snippet, that is what I meant.
(A key is never less than itself)

[Ryan Sleevi, 2016/05/18 02:07:40]

Right, I understood the snippet, but you said "never equal" and in the two cases
you gave, the keys are equal. I suppose you meant "never less" / "always equal",
correct?

[eroman, 2016/05/18 02:29:36]

Correct. I should have said "never less than"
