Raise an error and/or unit test if the Spree Deface Original Changed?

Question

Currently Spree Deface will log an error if the original view changes. For example:

Deface: [ERROR] The original source for 'spree/foo' has changed, this override should be reviewed to ensure it's still valid.

Does anyone know of way to raise an error if the original changed? A way to unit test that the original is the same as the override?

For example if I have an override that looks like:

Deface::Override.new(
  virtual_path 'spree/foo',
  name 'foo',
  insert_before: "[data-hook='button']"
  original: 'abcde12345',
  partial: 'spree/foo'
)

Is there a raise to an error if spree/foo changed? A way to unit test that spree/foo has not changed?

Thanks.
