Goal (Required)

As a developer using image-updater, I expect a high level of quality and good unit test coverage.

The current unit test coverage is around 55% as reported in Codecov Report in github actions CI run. We should aim for 80% unit test coverage.

Background (Required)

<Describes the context or background related to this story>

Out of scope

This epic focuses on unit test coverage and so will not include e2e tests.

Approach (Required)

• look at the current state of unit test coverage, and come up with a test plan
• start adding unit tests in pkgs with the lowest coverage, and gradually expand to cover all packages.

Dependencies

new unit tests are reviewed and merged into upstream image-updater project;

all tests passing without any regression.
