Course Ratings

Learning Objectives

Learning Objectives

MP3 challenges you to complete a similar set of tasks as MP2, but with less guidance. You’ll be add a new course rating feature to your application, including adding API server and client support and updating your application user interface.

The learning objectives of MP3 are similar to MP2. Specifically, after completing MP3 you should be able to:

1. Understand how a simple web server and client interact to exchange data
2. Add a new activity to the user interface, complete its user interface, and launch it from the main activity
3. Engage in test-driven development

Deadlines

Deadlines

Like MP2, MP3 has two deadlines. We provide 10 points for getting started on the MP promptly and earning a certain number of points before the early deadline. For MP3, you must earn 40 points by the early deadline. The remainder of the MP is due a few days later.

For MP3 the deadlines are:

• Blue Team Early Deadline: Thursday 11/30/2023 at 11:59PM Central Time
• Orange Team Early Deadline: Friday 12/1/2023 at 11:59PM Central Time
• Blue Team Deadline: Tuesday 12/5/2023 at 11:59PM Central Time
• Orange Team Deadline: Wednesday 12/6/2023 at 11:59PM Central Time

MP3 also has an extra credit deadline. If you submit a fully-completed MP3 by this date, you will earn a 105 / 100 on MP3.

• Blue Team Extra Credit Deadline: Saturday 12/2/2023 at 11:59PM Central Time
• Orange Team Extra Credit Deadline: Sunday 12/3/2023 at 11:59PM Central Time

Note that the extra credit deadline is designed to reward students who finish early and leave more time for staff to aid the rest of the course in the final week. As such, we will not provide additional support for meeting the extra credit deadline.

Objectives, Testing, and Grading

Objectives, Testing, and Grading

You will receive the MP3 test suites via email.

• If you are using Kotlin, move the file to the app/src/test/kotlin/edu/illinois/cs/cs124/ay2023/mp/test/ directory in your machine project. The file should be named MP3Test.kt.
• If you are using Java, move the file to the app/src/test/java/edu/illinois/cs/cs124/ay2023/mp/test/ directory in your machine project. The file should be named MP3Test.java.

Next, you’ll want to reconfigure grade.yaml in the root directory of your project to request that we grade MP3. Note that, like MP1 and MP2, your app will not compile after installing the test suites. There are a few things you need to add to get it to compile. These steps are covered on the MP3 lesson.

Objectives

Objectives

To complete MP3 you’ll add support for course ratings to your application. This will require adding routes to your API server to receive and deliver course ratings, support in your API client for using those routes, and modifications to the CourseActivity to display the rating for the course.

Testing

Testing

We have provided five test cases to guide your development. test0_ServerGETRating and test1_ServerPOSTRating tests your new server routes for retrieving and updating course ratings. test2_ClientGETRating and test3_ClientPOSTRating test that your API server and client work properly to retrieve and update course ratings. test4_RatingView tests that your CourseActivity displays the course rating properly. You will probably want to complete the tests in order.

Grading

Grading

Grading for MP2 is broken down as follows:

• 10 points for no detekt (Kotlin) or checkstyle (Java) violations
• 10 points for test0_ServerGETRating
• 20 points for test1_ServerPOSTRating
• 10 points for test2_ClientGETRating
• 20 points for test3_ClientPOSTRating
• 20 points for test4_RatingView
• 10 points for earning at least 40 points by the early deadline

You can estimate your grade at any time by using the Grade task available in Android Studio. This is an estimate, not an official score.

Submitting

Submitting

You submit MP3 by pushing to GitHub, in the same way that you did for MP2, MP1, and MP0. However, make sure that you have configured grade.yaml before pushing. We grade the checkpoint you have configured in grade.yaml. So make sure that is set up to grade MP3 once you are ready.

Cheating

Cheating

Please review the CS 124 policies on collaboration.

All submitted code will be checked for cheating. Cheaters will receive stiff penalties. Hard-working students who are struggling honestly for their grade demand it.
