Description

As a developer, I want to test whether an ingredient is deleted correctly when it is swiped from the list in the Storage activity. Please write an UI test for this purpose.

Technical Requirement:

1. Use the latest version of expresso for UI testing
2. For early implementation, use hard-coded mock data as the list of ingredients to be displayed.

Acceptance Criteria:

• Used expresso
• The test covers all the cases (swiping on an empty list, undo the deletion)
