Capability of unit tests

[MattGoldwater]

Hi Kent! I just read static-vs-unit-vs-integration-vs-e2e-testing-for-frontend-apps)

In your post you wrote, "Unit tests are incapable of ensuring that when you call into a dependency that you’re calling it appropriately"

What do you mean by this? Are you just saying a unit test can't confirm that the test is being called at the right time (though as you clarified you can check its being called with the right parameters)
