5//! Test the behavior of a single alarm.
6//! To add this test, include the line
7//! ```
8//!    multi_timer_test::run_multi_timer(alarm);
9//! ```
10//! to the imix boot sequence, where `alarm` is a
11//! `kernel::hil::Alarm`. The test sets up a series of
12//! timer of different durations and prints out when
13//! they fire.
