Grading and submission

Local tests and grading

Each assignment is shipped with two sets of tests:

• The tests defined under src/test/scala, these are usually incomplete: we strongly encourage you to write additional tests to exercise every aspect of your code. You can run these tests from sbt using the following command:

  test

• The grading tests, that we use to grade your assignments, these are provided as a "black box": you can run them but are not allowed to see their content, to encourage you to write your own tests. You can run them from sbt using the following command:

  runGradingTests

  Your grade is determined by the number of these tests that pass, see the next section to see how to actually get a grade.

(remember that you can always put ~ before an sbt command to automatically re-run it when you save a file)

Committing and pushing your code

You need to push your code to gitlab to receive a grade. If you forget, your grade will be zero.

If you've read the first few chapters of Git book as recommended, you must already be familiar with committing and pushing, but let's go over the basics once again:

At any point while working on an assignment, you can see what changes you haven't committed by writing:

git status

This will display the list of files you have modified since the last commit, to see the exact changes you made, run:

git diff

To save these changes in a commit, run: (replace "My message" by a message describing the changes since the last commit, see How to Write a Git Commit Message for some tips on writing good commit messages)

git commit -am "My message"

You can then synchronize your local git repository with the gitlab server by running:

 git push

Note that there are also graphical user interfaces to interact with git, for example VSCode has built-in git support.

Once you've pushed your code, you can see the result online by going to gitlab.epfl.ch/lamp/student-repositories-f19/cs210-GASPAR/pipelines where GASPAR is your username (you can also access this page from the main page of your repository by clicking on the rocket icon on the left side of the gitlab interface, then clicking on "Pipelines").

The grading pipeline contains two steps:

• compile: your code does not compile for grading if the job fail.
• grade: the job results in a warning if you do not get the maximum grade (10.00/10.00)

You can click on the jobs to see the logs:

Your grade is given on the line that starts with Your overall score for this assignment is

If you push to gitlab multiple times, your final grade will be based on the last commit you pushed before the deadline.

Troubleshooting

Wrong remote address

Cloning into 'cs206-example'...
GitLab: The project you were looking for could not be found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

If you get the above message, you ever used the wrong clone URL or you recently created your account on gitlab.epfl.ch, please wait 15 minutes and try again.
