Is the grader supposed to be really slow - I’ve tried to submit the assignment multiple times but it takes a good couple of minutes to get the results back.
Usually it doesn’t provide any feedback either so I’m not sure what the issue is when the tests fail. I just get “**An unexpected error occurred. Please try again later”
**
Is this supposed to happen?
Yes generally the case is so.
In coursera there is some feedback in the dropdown expanding arrow on the grader feedback, I am not sure here.
Please post a screen capture image of the grader’s report.
Thanks - think I figured it out last night. Just needed to make sure the unit tests were fully completed. Seemed to work better after that
That’s a good point. It doesn’t generally work to partially grade the assignments. It’s also a necessary, but not sufficient, condition to pass the grader that the unit tests all pass. The grader tests are (usually) different than the unit tests, so it is possible to pass the unit tests, but not the grader. There are usually ways to write the code that are not general, e.g. referencing global variables which are passed as parameters by their global references or hard-coding dimensions.
