Can we reuse the code in hasPath and BFS?

It seems this function does not give a vertex, it only prints some messages

I think it makes sense to name them as "get"

As for ASSERT_NO_THROW:
It seems you're generally not using exceptions. I think it is better to check some data about the graph in the assertion part. For example, if you have added one vertex, you can check that amount of vertices in the graph is 1.
