Summary

This PR introduces test coverage for the InlineDateAdapter to ensure robust handling of date transformations within form fields. Key scenarios tested include:

Updating Observation Dates: Tests confirm that when a new date is provided, the adapter correctly updates the obsDatetime field in the target field’s submission, ensuring accuracy in new entries.

Editing Dates in Edit Mode: Verifies that the adapter updates dates accurately when modified in edit mode, supporting seamless updates to existing records.

Conditional Side-Effects: Tests check that side-effects only trigger when there’s an actual change in the date value, avoiding redundant updates.

Commitment on Value Presence: Ensures side-effects are committed if the target field holds a value or has an existing submission, facilitating reliable updates when data is available.

Initial Value Extraction: Confirms that the adapter retrieves initial observation dates correctly from the previous value, essential for accurate pre-filling.
