V1.1

Usage

Download test.py move it into the directory that contains regression.py and bodyfat.csv

The contents of your directory should look like this:

$ tree
.
├── regression.py
├── bodyfat.csv
└── test.py

To run the tests, do

$ python3 test.py

Due to some of the tests needing to check the printed output of your function, you may have issues like "AttributeError: '_io.TextIOWrapper' object has no attribute 'getvalue'" if you don't run the tester in your terminal.

These tests do not check if plot_mse has a correct graph, only that it generates mse.pdf

Disclaimer

These tests are not endorsed or created by anyone working in an official capacity with UW Madison or any staff for CS540. The tests are make by students, for students.

By running test.py, you are executing code you downloaded from the internet. Back up your files and take a look at what you are running first.
