cs-6250-topology-test-script

Simple Pytest script to test the topologies for Project 4 of the CS6250 OMSCS Fall 20 class.

Disclaimer

This is by no means an official tool. It has been provided as an aid for students to test their code output, but getting a pass here doesn't guarantee passing the autograder. If you decide to use this piece of software, keep that in mind!

How to use

Disclaimer: Only tested on the VM provided. Python 2.7.6 and pytest 2.5.1 are already installed on the VM.

Clone/Download the repository and extract into the project's root folder.

Run py.test test_topologies.py inside the project's root folder to run the tests with the default settings.

Customizing

• If your reference files folder isn't named reference, you can optionally use an environment variable to set it. e.g.: If your reference logs are in a folder called results, run REF_DIR=results py.test test_topologies.py.

• If you want to skip/add some tests, currently you will have to do it by editing the file itself. Edit the file and comment/add the lines inside the TEST_TOPOLOGIES list corresponding to the tests you want to skip or add.

Troubleshooting

• If you're getting errors like len(ref_log) == 0, check if the file has the correct without carriage returns. If they have carriage returns, run something like dos2unix on the VM to remove them. I'd rather not change the test file to handle CRLFs because the final file should be submitted without them and forgiving it here could perpetuate a bad practice.
