freedesktop.libevdev

// libevdev, exercised without an input device.
//
// The package's whole reason to be a fork is `event-names.h` — 1,692 lines of
// generated tables mapping every kernel input constant to its string. So that
// is what the test asks about: a package that linked but whose tables were
// generated from the WRONG headers (the host's rather than the bundled ones,
// which produces a measurably different file) answers these differently.
//
// No device is opened. libevdev's name lookups are pure functions of the
// tables, which is exactly why they are testable anywhere.
