The final exam in some courses is a programming exercise where students create their own programs. Many people are just starting out with programming (and we are only human), so actually testing the code is extremely paramount.
Sadly, most traditional tools, like JUnit, are hard to use for newcomers, do not
allow easy sharing of test cases and are time consuming to write.
SimpleCodeTester is a website that solves this problem:
Everybody can create checks verifying program output in a simple and intuitive
format. The editor for this supports syntax highlighting to make it a bit more
enjoyable :)
Finally, users can test their code against all submitted tests. Everybody is free to participate and create tests - everybody will benefit from them instant they are submitted.
Great care was taken to ensure the online runtime environment is secure (it is run with a restrictive security manager and each submission is sandboxed in its own Docker container, without any capabilities or network/disk access). We also conciously decided, that no user submissions should ever be stored - your code is received, passed to the sandbox via stdin, fully compiled in-memory and the last traces of it die with the result response. Feel free to have a look at how it is implemented though!
The following is a submitted check
And we also have a dark theme!
If you submit your code, it will automatically be tested against all checks.
Here is our demo test from earlier, all grown up and failing! In such a case,
we try to match the output your program produced with the expected output and
provide useful error messages.
