* @page test_events Events test
*
* File: @ref testevt.c
*
* <h2>Description</h2>
* This module implements the test sequence for the @ref events subsystem.
*
* <h2>Objective</h2>
* Objective of the test module is to cover 100% of the @ref events subsystem.
*
* <h2>Preconditions</h2>
* The module requires the following kernel options:
* - @p CH_USE_EVENTS
* - @p CH_USE_EVENTS_TIMEOUT
* .
* In case some of the required options are not enabled then some or all tests
* may be skipped.
*
* <h2>Test Cases</h2>
* - @subpage test_events_001
* - @subpage test_events_002
* - @subpage test_events_003
* .
* @file testevt.c
* @brief Events test source file
* @file testevt.h
* @brief Events test header file

* Two event listeners are registered on an event source and then unregistered
* in the same order.<br>
* The test expects that the even source has listeners after the registrations
* and after the first unregistration, then, after the second unegistration,
* the test expects no more listeners.<br>
* In the second part the test dispatches three event flags and verifies that
* the associated event handlers are invoked in LSb-first order.
