• Jasmine Spies help  us to mock the execution of the method /  function.
• It’s a easy way to check a method was called or not, without leaving Subject Under Test(SUT).
• We can chain the spyOn method to get dummy return value using .and.returnvalue()
• spyOn can call the original function using .and.callThrough().

• Content box: The innermost box, where text and image are placed.
• Padding box: It is a space between the element content and border of the element.
