Let me do that now. Test fixture, CheckoutTests, CanGetTotalForMultipleItems. checkOut.addItemPrice("a", 1). checkOut.addItemPrice("b", 2). checkOut.addItem("a"). checkOut.addItem("b"). Int total = checkOut.calculateTotal(). ASSERT_EQ(3,total). As the total should be the sum of one and two for the two items A and B. Let's build this and run it. Excellent. My new test is failing. Great. So I have a failing unit test, so onto the green phase and let's make it pass. Things start to get a little bit more complicated with this test. What I wanna try and do the simplest thing I can to get the test to pass. To do that I'll go ahead and…
