I'm trying to understand this example in paper Code coverage and test automation. Please refer to the figure.

Why is (n3, n4, n1, n3) a prime path, while (n3, n4, n1, n2) is not?

  • The imagine is a bit confusing - the outbound edges of n4 and n5 are pointing to another edge, not clearly to a node. Jun 6, 2022 at 8:16
  • @JoãoFarias I agree. Let's presume they are pointing to n1. That's how I interpreted it.

I don't think the list on the right-hand side is a complete list of paths.

For example, the graphic is also missing a couple paths beginning with n_0:

  • n_0 -> n_1 -> n_3 -> n_4
  • n_0 -> n_1 -> n_3 -> n_5
