a. The test loops through each feed in the allFeeds object and ensures it has a URL and name defined and that the URL and name is not empty, by using the $.forEach() inside the it.

b. Test suite "The menu"

• Test that ensures the menu element is hidden by default is done by checking the .menu-hidden class on the body tag.
• Test that ensures the menu changes visibility when the menu icon is clicked is done by triggering the click event for the menu-icon-link and checking for menu-hidden class on the body tag.

c. Test suite "Initial Entries" Test that ensures when the loadFeed function is called and completes its work, there is at least a single .entry element within the .feed container.

• loadFeed requires an id parameter and beforeEach cannot be inside a loop therefore id is incremented inside each it to allow the next feed to be loaded
• on ajax success the feed's first entry is stored in feedEntry.h2
• on ajax failure 'feedEntry.h2' will contain Not Found
• it is expected that feedEntry.count not toEqual '0' and feedEntry.h2 not toEqual Not Found

d. Test suite "New Feed Selection"

• this test is based on two nested loadFeed functions that mimic a click event
• the first loadFeed is called with id = 0 in beforeEach and the .entry h2 is stored in feedEntry0,
• $.empty() is called to ensure clean container for the next load
• the second loadFeed with id = 1 is called inside the cb function of the first loadFeed and the .entry h2 is stored in feedEntry1
• it is expected that feedEntry0 is not toEqual feedEntry1
