Found when I was tinkering with custom tests. We can use require()-alike functions for specific tests, e.g., related to the fs operations, where a test case should not proceed.

For example, here:
https://github.com/trailofbits/medusa/blob/69fa1587de6e42e382a835f40316c4ec8382e8f4/utils/testutils/test_directory_utils.go#L21-L22

When a file (sourcePathInfo) does not exist, a test case continues and panics here:
https://github.com/trailofbits/medusa/blob/69fa1587de6e42e382a835f40316c4ec8382e8f4/utils/testutils/test_directory_utils.go#L26-L26

just replace it with the require.NotNil(t, sourcePathInfo), and so on.
