DEVRY CIS 339 iLab 7 Object Oriented Application Coding Check this A+ tutorial guideline at For more classes visit Your demonstrations of how to create both method contract and the method specification for the GetCourseByCourseID() method of the CourseList class were very well received by your team members. They then asked you for one final demonstration of how to implement the method specification using an object- oriented (OO) programming language and see the method actually execute. You realize that it is easy to implement the method specification in an OO programming language, but it is hard to test it because the rest of the application is not developed yet. You decided, therefore, to write two pieces of code. Code that implements the GetCourseByCourseID() method Code that implements a unit test for that method alone (outside of any other application code) This way you can demonstrate the method implementation and also verify its correct behavior. You are under a deadline constraint for this deliverable, so you asked some of your peer architects for help. They each are well versed in different OO languages like VB.NET, C#, and Java and they all have done unit testing before so they are familiar of how to construct one.

Y OUR PEER ARCHITECTS PROVIDED YOU WITH PARTIALLY - COMPLETED SHELLS FOR YOUR DEMONSTRATION. E ACH SHELL CONTAINS : COMPLETE CODE FOR THE C OURSE CLASS ; PARTIALLY COMPLETED CODE FOR C OURSE L IST CLASS ; AND COMPLETE CODE FOR THE C OURSE L IST T EST CLASS THAT UNIT TESTS THE C OURSE L IST.G ET C OURSE B Y C OURSE ID() METHOD. Y OUR TASK IS NOW EASY. J UST SELECT ONE OF THESE SHELLS AND COMPLETE THE CODE FOR THE PARTIALLY COMPLETED C OURSE L IST BY CODING IT G ET C OURSE B Y C OURSE ID() METHOD. W HEN YOU COMPILE AND RUN THE SHELL, IT WILL AUTOMATICALLY TEST YOUR G ET C OURSE B Y C OURSE ID() CODE TO ENSURE ITS CORRECT BEHAVIOR. D ELIVERABLES O NE W ORD FILE THAT CONTAINS THE FOLLOWING. A COPY OF THE CODE YOU WROTE FOR THE G ET C OURSE B Y C OURSE ID METHOD () OF THE C OURSE L IST CLASS IN YOUR FAVORITE OO PROGRAMMING LANGUAGE A SCREEN SHOT OF THE OUTPUT OF RUNNING THE PROVIDED UNIT TEST IN THE SHELL ( THE C OURSE L IST T EST CLASS ) SHOWING THAT YOUR CODE WORKS AS EXPECTED.
