@MiahaCybersec I have submitted some review comments on the tests and code.

This is good work that will make it easier for the Copa project to on-board new contributors, well done!

My requested changes are largely around improving the story telling around how copa works which will benefit both early adopting end-users and new contributors.

I have one question on the TrivyOpts and why that include non-trivy related fields (there's a bk client in there)

The most important thing to do with work like this is to test it extensively and ensure that no behaviour has changed as a result of the submitted changes.

I like this test!

It is easy to understand from having worked with you this.

That test names could be even more explicit so as to differentiate between two types of tag that we are considering here in this test.

We have two tags

  1. The user-supplied tag which leaves a breadcrumb indicating that the image was patched by copa
  2. The imagename tag which appears at the end of the image

If you use ImageTag and UserSuppliedTag in the test names a new contributor (or a curious end-user) would more easily understand this test.

In the test case we are only supplying a user patched tag, which can either be empty "", or supplied "example-supplied-tag". The differentiation is done within the function itself, not the parameters being passed in.

This is why for some of the test cases, an empty string is passed in but the expected result contains defaultPatchedTagSuffix

Extracted BuildKit client configurations from TrivyOpts into a new BkClient struct. Updated related functions and tests to accommodate this change, improving modularity and readability.

Renamed the `TrivyOpts` struct to `ScannerOpts` to better reflect its purpose. Added an explicit channel parameter `ch` for error handling throughout the functions to improve code clarity and maintainability. Added new test cases to cover scenarios with digest-referenced Docker images.

LGTM, will wait to merge. @MiahaCybersec @RobertKielty and I discussed adding canary testing before merging large changes.
