If a log string is the exact length of a log fragment buffer

Hello!
This test looks good to me. I have tested it and it seems to be working well.
I appreciate all of the assert and expect statements. I do have one
comment below.
Although, I would be happy to set this as reviewed by me after that
comment is responded to.
Thanks!

Should this be an EXPECT instead? It doesn't seem like the test needs
to fail immediately if this fails. Let me know what you think.
I think ASSERT is appropriate here. This isn't testing anything
(unless you don't trust memset). It's ensuring that the test data
I generate is what I expect otherwise the following testing is
invalid.
This is redundant because the first 3 lines must produce the expected
string, but I put it in to prove to myself that I can do math and
decided to leave it in.
