Towards perfect testing of applications checkpoint-restore

One Line Summary

The talk is about our experience at CRIU with testing C/R technology.


Since the project start the whole testing was about writing individual tests that exploit some Linux API bit and checking that criu saves it and restores well.

Eventually we’ve come to the conclusion, that this approach doesn’t work well, since the variety of API combinations exceeds the human ability to write tests.

In this talk I will try to outline the way to test CR and problems that appear while going one.
