test.rkt

The format of these files are very simple, the contents have the following form.

(result (student-function our-test-input)) 
(expected expected-output)      

The expression in the result line will be evaluated in the language chosen in the options file. The value produced will then be compared to the value in the expected line, using the function equal?. If these two values are the same, and there were no errors while evaluating any expressions, the submission will pass the test. Unfortunately, this is not a built-in form in Racket, so you can only check them in check-expect form or use rst to actually run them on the server. You can still call other Racket functions in the test case, even something like a cond with multiple cases depending on what the student's function does. There will be more tips on writing tests in the basic and correctness test sections.
