About:
Umockdev is a Linux testing framework that creates mock hardware devices in a sandboxed environment. It allows developers to simulate USB, PCI, and other device interactions without physical hardware, making it ideal for unit testing and bug reproduction. The tool intercepts low-level system calls to provide deterministic, repeatable test results.

Key Features:

Sandboxed device simulation without root privileges
Support for USB, PCI, SCSI, and other device types
Record and replay real device interactions
Integration with GLib/GObject and standard Linux APIs

Use Cases:

Unit testing device drivers and hardware-dependent applications
Bug reporting with reproducible device interaction logs
CI/CD testing without requiring physical hardware

Alternatives:

qemu – Full system emulation vs Umockdev's lightweight device-level mocking
libvirt – Virtualization management vs Umockdev's unit test-focused device simulation
