\n

\n \n

\n
\n\n### Communication between layers\n\n1. UI calls method from ViewModel.\n2. ViewModel executes Use case.\n3. Use case combines data from Album and Photo Repositories.\n4. Each Repository returns data from a Data Source (Cached or Remote).\n5. Information flows back to the UI where we display the list of posts.\n\n\n\n### Scenario\nUsed https://jsonplaceholder.typicode.com/ as a public api to generate fake data for testing\n\nAt a glance:\n\n- Created a list of Album\n- In the Item of each Album, showed Album name.\n- When user taps on Album, new page will be shown which includes list of photos.\n- when user taps on photo, show image bigger through transition.\n- Were Written tests to completely cover Exceptions/Expectations\n- And: \n - Supported orientation change\n - Supported offline mode" }, { "path":
