<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->

The mock for this test is not actually mocking the function being used.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

The function being used is getting mocked.

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
