CS131 HW5 Sample Grading Script

• This is a real grading script used in 2019 Fall, but all test cases are omitted.

Usage

• Create a folder for each submission in the submissions folder
• Put expr-compare.ss in the corresponding folder. Make sure there are #lang racket and (provide (all-defined-out)) lines in that file.
• Please make sure that in your expr-compare.ss, there are only definitions. Top-level function calls such as (test-expr-compare test-expr-x test-expr-y) may cause compiling error and thus not allowed.
• Execute the script via

  racket ./main.rkt ./submissions

• Go to each subfolder in the submissions folder and check the report.txt.
• For each test case, there are 4 kinds of results:
  • AC (Accepted): Correct
  • WA (Wrong Answer): The answer is wrong.
  • RE (Runtime Error): An exception is thrown during this test case.
  • TLE (Time Limit Exceed): Your program stuck on this test case for >600ms.
• There are about 50 test cases. Among them, about 30 are included in test-case.rkt.
  • So you can expect to get approximately 60% if you passed all of the test cases.
  • I reserve the right to change all cases if I see someone tries to enumerate test cases instead of implementing the program.
• To add new test cases, modify test-cases.rkt.
