I use repl.it, and one problem i note, is that each new test case has to be added by many gui-web clicks. it is both slow and annoying, and makes it harder to : 1) send to other teacher to review the testcase 2) store the assignment in github ( for backup/ development/review) 3) see all tests cases at once 4) transfer info between sites ( if a better site is found, i want to transfer all the assignments data inc. testcases easily to the better site).

Saw in another SE-CS-educators thread, STEPIK site and in some other thread VPL for Moodle was suggested. How many have used VPL-Moodle for K12 ? and STEPIK ? ( grades 10-12) Are there any other autograder sites, that support one-file-that-contains-all-test-cases ?

  • $\begingroup$ Auto grader sites could come and go. How to evaluate and select one could be useful. With enough rep, soon available, experience could be shared in chatroom. $\endgroup$

At the TU Delft we've developed WebLab, which is used in various CS related courses. It has support for programming assignments, for which students code their solutions in a web-editor, and run their code against their own tests, and the spec-tests.

  • Grades are automatically calculated based on the number of succeeding specification tests.
    • As a Course Manager, you specify the spec-tests by writing JUnit tests in a single file (in case of Java).
    • Students can run the spec-tests, and the UI will only reveal the test score to students, while managers have access to the complete output of the program.
  • Optionally, the automatically computed grade can be combined with manual grading components (e.g. a checklist).
    • It provides an interface to walk over all submissions.
    • Each Grader can be assigned their share of the submissions to be graded

Other types of assignments supported include: Essay questions (manual grading), Multiple Choice questions (automatic grading), File Submission questions (manual grading) and Peer Review questions (manual grading). For programming assignments it has built-in support for Java, Scala, Python and C, but this can be extended with any language for which you can provide a Docker image that handles input/outputs results in WebLab format.

You can sign up and enrol for this demo-course to get an idea of its interface as a student. If you're interested, we can set up a demo course for you by submitting a course request (sign in first).
