A public repository for codewars.com, where issues can be tracked and wiki documentation can be contributed to.
If the issue is related specifically to the execution of code (Test Frameworks, test output, etc) then a better place to log would be within the Codewars Runner CLI repository.
If you are looking to express an interest in adding a new feature to Codewars, you may do so here. Please be sure to check that it hasn't been logged already.
