ASSERT_TRUE() ?

[jbroman, 2014/03/21 15:39:34]

Unfortunately, this isn't directly in the test or its SetUp/TearDown.
ASSERT_TRUE works by emitting a message (by accessing a singleton) and then
returning. (But this is in a constructor.)

I look a  little more closely at exactly how gtest handles ASSERT_TRUE and
EXPECT_TRUE. Apparently it *is* okay to put a non-fatal EXPECT_TRUE here, so I'm
adding that (even though it will still result in more errors later in the test,
this might help in debugging), but I don't think it's worth the complexity of
plumbing the boolean back to the test to ASSERT_TRUE.
