Unit tests can test sub-problems very well. TSP solver surely will be
composed of some sub parts, you can test them. If you don't you will
have less certainty where the problem might be when it strikes.

Testing whole problem solver is useful too. You know when you break it
by some modification (i.e. adding optimization).
