Should check_installed() skip tests instead of error?

[olivroy]

If check_installed() is called in tests, we would get an error (non-interactive sessions)

But could there be an option to skip the test instead?

Thanks

Edit: I mean when one of the packages is not installed!

Example in cynkra/dm#2040 (comment)

How is that different from the behavior we have today?

Wrong repo 🤦

For context: in dm, we have a wrapper around check_installed() that first calls is_installed() and (only in tests) calls skip() with an appropriate error message. This means that we almost never need to call skip_if_not_installed() in tests. Because we also test with every weak dependency missing, in a matrix, this also checks for us if our user-facing code has appropriate checks.
