Task 1: Using the following class diagram generate an integration test order that minimizes the number of stubs needed to test each class in the diagram during integration. If any stubs are needed, identify which class(es) requires a stub during testing. Explain how you obtained the class integration test order. Hint: You may want to replace the class names with the letters before generating the integration test order. Show a key mapping the letters to the class names.
