This file describes the directives and concepts tested by this test set.
 
test set name: test4
 
directives:
ex_init, ex_start, t_create, t_start, tm_tick, i_return,
tm_set, tm_get, ev_receive, t_mode
 
concepts:
 
a. Verifies timeslicing ( all tasks are in timeslice mode ).
 
b. Verifies the tswitch user extension.
 
c. Verifies the no preemption mode.
 
d. Verifies time-slice gets reset even if only one task ready.
 
output:
The task name and the current time are printed out each time that a new
task is being dispatched. The configured timeslice is 100 ticks
( 1 second ); therefore, a task name and the time are printed once
every second. After each task runs 3 times, task 1 changes its mode to
no preempt and runs for about 6 seconds and then changes its mode back to
preempt mode.
