Integration Testing of CADSimulator This is an individual lab. You may not discuss any aspect of it with other students. Goal: Write an automated integration test (using JUnit and UISpec4J) to verify that simulation status shows "Ready" in the GUI after a script has been loaded. The overall approach: Prepare config and script files as needed. Create an instance of CADSimulator, not the model or anything else. Don't call the main() method. With UISpec4J grab the value of the simulation status field and verify that it says "No Script". Using the CADSimulator instance, obtain a reference to the Coordinator and invoke a method to load a script file. With UISpec4J grab the value of the simulation status field and verify that it says "Ready". Submission: Submit your JUnit test class to PolyLearn.
