documentation request for test_one_solution.py

[ziwenyd]

Hi authors, can you add some documentation for the test_one_solution.py file please? I have 2 questions here

• what does test_one_solution.py do? (what's the input and output?)
• How to use the file? is there a bug or I need to run some other scripts before runing test_one_solution.py?
  • the default value for param --test_path (data/APPS/test)doesn't exist
  • there is no default value for param --code_path, what should I specify for it?

Thanks in advance!
