What is the best practice in a monorepo to ensure using only local versions?

[EgoziE]

I have the following monorepo:

root
- pkg-A
- pkg-B

pkg-A is dependent of pkg-C which is not in the same monorepo.
pkg-C is dependent of pkg-B.

This means that when introducing changes to pkg-B, these changes are not tested during PR.
Only after a new version of pkg-B is released and is updated in pkg-C then I can suddenly see problem I could have avoided.

My solution is to force versions through root resolutions like so:

resolutions: {
  "pgk-A": "^1.0.0",
  "pgk-B": "^1.0.0"
}

It works for me, but is this a good practice?
Any suggestions how to deal with such problems (without changing pkg-C of course)
