Generic Grader

A collection of generic tests for grading programming assignments.

This project is still in very early development. Expect breaking changes.

Installation

pip install generic-grader

Usage

Name the reference solution reference.py, and place it in a tests subdirectory of the directory containing the student's code.

Add a configuration file for the assignment in the tests subdirectory (e.g. tests/config.py). It might look something like this:

from parameterized import param
from generic_grader.style import comments # Import the tests you want to use
from generic_grader.utils.options import Options

# Create tests by calling each test type's build method.
# They should all start with the word `test_` to be discovered by unittest.
# Adding a number after `test_` can be used to control the run order.
# The argument is a list of `param` objects, each with an `Options` object.
# See the Options class for more information on the available options.
test_01_TestCommentLength = comments.build(
   [
      param(
          Options(
              sub_module="hello_user",
              hint="Check the volume of comments in your code.",
              entries=("Tim the Enchanter",),
          ),
      ),
      param(
          Options(
              sub_module="hello_user",
              hint="Check the volume of comments in your code.",
              entries=("King Arthur",),
          ),
      ),
   ]
)

Run the tests.
```
python -m unittest tests/config.py
```
