1This document defines the plan for stress testing of POSIX Clocks
2and Timers.
3
4First a list of the features that will and will not be tested is given.
5
6Then, an attempt is made to break down the features into possible testing
7scenarios.  Not all of these may be implemented.  The assertions.xml file
8will have the additional detail on which were chosen for implementation.
9
10Features To Be Tested
11=====================
12The following features will be tested:
13 - Repetition of key clocks/timers functions.
14 - Behavior of normal functions under heavy memory usage.
15 - Behavior of normal functions under heavy CPU usage.
16 - Behavior of normal functions under heavy timers usage.
17
18Features Not To Be Tested
19=========================
20API testing of the clocks/timers functions is considered to be done by
21the conformance section.
22Functionality testing is considered to be done by the functional section.
23Stress testing involving specific hardware is not defined at this time.
24Stress testing involving use interaction is not defined at this time.
25
26Test Case Scenarios
27===================
28Some potential test case scenarios are listed after each functional
29area.
30
31Repetition
32----------
33- Repeat key functional tests multiple times.
34- Set clock time forward and backward multiple times.
35- Set up a repeating timer and block the signals to attempt to get a large
36  overrun.
37- Send many (1000s) of signals at the same time.
38
39Heavy Memory
40------------
41- Set memory to 95% and run through key clocks functions.
42- Set memory to 95% and run through key timers functions.
43
44Heavy CPU
45---------
46- Set CPU to 95% and run through key clocks functions.
47- Set CPU to 95% and run through key timers functions.
48
49Heavy Timers
50------------
51- Set up >10,000 timers and run through key clocks functions.
52- Set up >10,000 timers and run through key timers functions.
53
54* Will also perform kernel profiling on select stress tests.
