Testing an application using libusb without real hardware

Question

One part of the application that I am writing uses libusb to communicate with the device, and it is difficult for me to test my code. Is there a framework for creating fake USB devices or another way to mock libusb in order to better automate testing, be able to test on CI, play back boundary cases, etc.?

Answer 1

umockdev provides tools for recording the properties and behavior of specific devices and for running a program or a set of tests on a test bench with previously loaded devices loaded.
