##### SUMMARY

When using `ansible-test sanity --test import` on a collection, it is possible for an import error in a module_util to go unreported. Additionally, this can lead to import errors in modules that use that module_util reporting failures which do not indicate the actual source of the problem.

##### ISSUE TYPE

Bug Report

##### COMPONENT NAME

ansible-test

##### ANSIBLE VERSION

devel

##### CONFIGURATION

N/A

##### OS / ENVIRONMENT

N/A

##### STEPS TO REPRODUCE

1. Check out https://github.com/aristanetworks/ansible-cvp/releases/tag/v1.0.0
2. Copy the `arista` directory into a collection root.
3. Run the import sanity test: `ansible-test sanity --test import --docker -v --python 3.7`

##### EXPECTED RESULTS

```
