This is check50, a command-line program with which you can check the correctness of your programs.

check50 is a testing tool for checking student code. As a student you can use check50 to check your CS50 problem sets or any other Problem sets for which check50 checks exist. check50 allows teachers to automatically grade code on correctness and to provide automatic feedback while students are coding.
You can find documentation and instructions for writing your own checks at https://cs50.readthedocs.io/projects/check50/.
Then the semantics of a line like if results[0].passed would reflect the question being asked better than if results[0].status.

Because .reject sends "", the below fails with a ValueError, https://cs50.me/checks/67d9247dd25379fc1c646168a2eff04f10658314.
Sample input for cs50/2017/fall/sentimental/mario/less, per @curiouskiwi:
def main():
while True:
#height = get_int("Height: ")
height = int(input("Height: "))
if height < 24 and height >= 0:
break
if __name__ == "__main__":
main()
Which simply runs, given foo.py,
python -m py_compile foo.py
in order to check for syntax errors?
Hi, it's really great that students can see the check50 code.
For this file https://github.com/cs50/check50/blob/pset3/checks/cs50/2017/x/fifteen/checks.py
check50 overwrites the draw() function of the student. This causes errors if the student is tracking the blank cell in her draw() function.
See: https://cs50.stackexchange.com/questions/26421/pset3-fifteen-c-passes-local-tests-but-fails-check50-with-timeouts/26422
Suggest not overwriting the draw() function and perhaps looking at the log file (and logging invalid attempts?)
Thanks for a really great course!
Currently, if I run on the attached caesar.c:
check50 -d --offline cs50/2017/fall/caesar caesar.c
I get:

The issue is that the incorrect student submissions shifts an ascii value outside of the 0-127 range. Not sure if my fix is the right thing to do, but works for the time being.

Aok to wait until we have an actual use case (e.g., a pset4 problem).
Line 20 of setup.py looks for "/Applications/Python 3.6/Install Certificates.command", which does not exist when python 3.6 is installed via homebrew.
It looks like https://stackoverflow.com/questions/44649449/brew-installation-of-python-3-6-1-ssl-certificate-verify-failed-certificate may have an answer, but someone who knows what's going on should probably verify this.
Might as well adopt a word students and teachers will see elsewhere?
It occurs to me that factoring out the checks to its own repo will also help with versioning, since we shouldn't really have to increment check50's x.y.z version just because we add new checks.

https://github.com/cs50/check50/blob/v3dev/check50/internal.py#L82-L85
My code uses the minor scale pattern to calculate semitone distances and thus, frequencies of each note, and the "produces all correct notes for octaves 3-5" passes but fails for Ab3 and Bb5. I believe this to be because check50 wasn't implemented to recognize that some notes are enharmonic (Ab3 is the same as G#3 and Bb5 is the same as A#5).
// Calculates frequency (in Hz) of a note
int frequency(string note)
{
char letter = note[0], acc = '\0';
int octave;
// parse the note string
if (strlen(note) == 2)
{
// 0 - 9 are contiguous so arithemtic can be done with them
octave = note[1] - '0';
}
else
{
acc = note[1];
octave = note[2] - '0';
}
// for octaves of A
int f = DEFAULT_FREQ * pow(2, octave - DEFAULT_OCTAVE);
int frequency;
// accidentals
int qual = 0;
if (acc != '\0')

}

Instead of just printing "check50 ran into an error while running checks!", it would be great if errors were allowed to propagate when run with --verbose. It would also be nice to have a self.info function for checks that could be used to print debug messages with --verbose.
check50 cs50/2018/x/resize/less is failing even though the output matches with staff version.

I'm really excited to see that this implementation is going to be in bash.
If there would be a contribution guide, I'd like to contribute as well.
Not sure if we expect that or if there's a cleaner way to detect this but in sentimental/mario for example, the check for rejecting non-integer values still passes even if the user is taking input using the following which would throw an exception in this case:
$ cat mario.py

@crossroads1112 @Jelleas any workarounds or should we downgrade back to the latest 3.6?
See also pypa/setuptools#1401.
E.g., should avoid hardcoding compilation lines like self.spawn("clang -o resize resize.c -lcs50").exit(0), since we tend to tweak CFLAGS each year. Ideal to factor that var out so that, on a per-semester basis, it can be configured to match the IDE. Else we'll have to grep through checks each year tweaking, which doesn't feel ideal? Perhaps we should just add a .clang check that wraps .spawn?

E.g., to swap in our own draw function in pset3. Worst case, we can pattern-match on functions' names and just mangle them, linking in our own identically named function. But ideal to parse things out perhaps.
During the CS50 teacher workshop I've been trying to implement java checks in the check50 and submit50 repos. I think I have correctly implemented the checks, but I believe that a java compiler is missing from the server that is running check50. Below is the link to my java checks.
We think they will work if a java compiler is installed. I hope it's as simple as the following command sudo apt-get install openjdk-9-jdk-headless
You can run this in the cs50 IDE :
check50 cs50/2017/x/isPrime/java@jake23hogs/checks
Link to repo:
https://github.com/jake23hogs/checks/tree/master/cs50/2017/x/isPrime/java
Use case is to check whether a student ran one or more commands, as in a Linux lab. Would be ideal if history file also reported CWD after each command.
But let user proceed with old version by re-running with -f or --force.
If possible, since #18 (comment). Ideally with base URL baked in so you can call with just, e.g., self.get("/foo").
When checking my vigenere code, I realised that part of the baz check of hello, world! would actually fail caesar too.
More specifically my original caesar code passed the check50, but if running with argument 25, for "hello, world!" I would actually get the wrong answer. This was not picked up by check50 .
I've now corrected my code, which should now produce the right answers!
~/workspace/ (v3dev) $ check50 -d problems/caesar/__init__.py
Sorry, something's wrong! Let [email protected] know!

Just 3 fixed dots instead like other progress prompts.
Use case is wanting to run some checks for a lab without giving the lab a public slug (as would happen by creating a check50 key in .cs50.yml). Could we assume that the check should be run on the entire contents of $CWD?

Not sure why, it worked three or four months ago when I finished this task. I didn't submit it because I wanted to finish game of fifteen too and to submit both. I came back today to finish it and I had to do update50, so maybe that is a reason for this problem. Also, pset3 find didn't work until I run make all again and recompiled it.
Can we more rigorously comment all blocks of code? Has taken a while to onboard (e.g., me :) to how things work internally!
@brianyu28, mind pasting a sample JSON output object here (that has some to-be green, red, and yellow results)?
For consistency with a standard key name, rather than use our own (more verbose) one.
