Testing instructions

Deleted/Added level diff

• In a library create this structure Section>Subsection>Unit>Components.
• Add the new created Section to a Course.
• In the library delete the Subsection and create a new Subsection>Unit>Component structure in the Section.
• Publish all the changes.
• In the Course, click on the sync button of the Section.
• Go to the deleted Subsection, verify the new Deleted diff state.
• Go to the added Subsection, verify the new Added diff state.

Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Deprecated propTypes, defaultProps, and injectIntl patterns are not used in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Imports avoid using ../. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'
