umockdev

record mock hardware devices for bug reports and regression tests

Documentation

• The README.rst has an introduction and command line examples
• There are examples in C and Python that show how to build simulated devices from scratch for test suites
• I wrote some blog posts about the introduction (that doesn't provide much over README.rst, though), record/replay of input devices, record/replay of tty devices, and record/replay of Unix sockets.

Projects that use it

• The upower test suite mocks batteries, ACs, and UPS devices.
• The gvfs test suite contains ioctl records from a digicam and a phone music player and uses them for regression-testing the PtP and MTP backends.

Development

umockdev is pretty much demand driven. When you want to do something new in that area that umockdev doesn't support yet, please check/file a bug. The current Ubuntu Saucy blueprint has some work items related to umockdev which I am working on right now. Also, please feel free to grab me on IRC (pitti on freenode) or send me an email.
