Unit Testing and Mocking

One Line Summary

Discussion on the possible value of adding unit tests to the kernel.


Currently most testing in the kernel is done on a booted kernel and is primarily driven by the userland. Some portions of the kernel may be well tested, but in practice many code paths in the kernel are not exercised before code is submitted. Unit testing and mocking is one possible way to make it much easier to exercise arbitrary code paths.
