  See how to simulate the behavior of objects, services, and other dependencies during unit testing. Get an overview of why a mocking framework helps and how it works.

  You can use the InterSystems ObjectScript Extension Pack in Visual Studio Code instead of Atelier, which has been deprecated.

  Reference	Timestamp	Commands
  Create the dependencies*	8:48	set mathService = ..CreateMock()
  Inject dependencies in the tested class	8:48	set testedClass = ##class(MockDemo.CTestedClass).%New(mathService)
  Record expectation objects*	8:48	do ..Expect(mathService.Add(1,2)),AndReturn(3)
  Replay expectation objects*	8:48	do ..ReplayAllMocks()
  Execute the tested method	8:48	do $$$AssertEquals(testClass.SumOperation(1,2), 3)
  Verify any issues*	8:48	do ..VerifyAllMocks()

  
  *These commands require the class to extend a mocking framework. See below for a link to the MockManager framework discussed in the video.
