A website that allows you to test your code against crowdsourced test cases, and increase chances of not failing APS105 by 1%.

As students dying in programming labs, we are always debugging and checking differences between our output and the solution. diff is a powerful command line tool to do this. But its outputs is......quite enigmatic.

This isn't even the worst part. Making the test cases themselves can take so many days. No one can guarantee that they checked for all the corner cases. We thought, what if we could put together all the test cases that every person made, and have a beautiful UI to show differences between output files? So, here's to my poor Reversi AI and to whoever thought using automarkers alone to mark coding assignments is fair.

The front page of Codecker shows all the courses we currently support. It's easy to search, add courses, edit their descriptions, and delete them.

Similarly, within each class, the administrator can add assignments with a zip file for download and the expected output. The zip file contains the test case and a .bat file that helps compile and run the program.

Yvonne wrote the batch script to compile programs and generate an output file. Jack handled the backend of the website, with Restful Routing and the database (MongoDB). Grace worked on the frontend of the website, the logo and directed our demo videos.

Writing an algorithm to compare two files in Javascript was the biggest challenge. We had to research and use open source code to our aid (many thanks to this).

Having a fully functioning website! The UI is gorgeous and all of the basic features are implemented, too.

Deploying codecker to be used by students, additional features, finding administrators to manage the database and the website, and touching up on the UI to make it look even nicer.
