0029 This file describes the directives and concepts tested by this test set.
0030
0031 test set name:  test24
0032
0033 directives:
0034   ex_init, ex_start, t_create, t_start, tm_tick, i_return, t_ident,
0035   ev_receive
0036
0037 concepts:
0038
0039   a.  This test is a cyclic version of test1.  The times printed by
0040       each test should not skew as in test1 (see output section).
0041
0042   b.  Verifies system can create and start both the executive's system
0043       initialization and idle task.
0044
0045   c.  Verifies executive can swap between three application tasks at the
0046       same priority and the executive's internal idle task.
0047
0048   d.  Verifies can print strings to the CRT on port 2 of the mvme136 board
0049       using Print and Println in the board support package.
0050
0051   e.  Verifies interrupt handler can handler a task switch from an interrupt
0052       as specified with the i_return directive.
0053
0054   f.  Verifies executive initialization performed correctly.
0055
0056   g.  Verifies the executive trap handler except for the halt function.
0057
0058   h.  Verifies that a task can get the task identification number of itself.
0059
0060 output:
0061   "TA1" is printed once every 5 seconds.  "TA2" is printed once
0062   every 10 seconds.  "TA3" is printed once every 15 seconds.
0063
0064   The times printed should be multiples of 5 seconds for TA1, 10 seconds
0065   for TA2, and 15 seconds for TA3.  If this does not happen, the calendar
0066   time does not correspond correctly to the number of ticks.
