22	>	* tests are:
23		*
24		* <ol>
25		*
26		* <li> All assertions in code running in generated threads must use
27	<	* the forms {@link threadFail} , {@link threadAssertTrue} {@link
28	<	* threadAssertEquals}, or {@link threadAssertNull}, (not
27	>	* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
28	>	* #threadAssertEquals}, or {@link #threadAssertNull}, (not
29		* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not
30		* particularly recommended) for other code to use these forms too.
31		* Only the most typically used JUnit assertion methods are defined
32		* this way, but enough to live with.</li>
33		*
34	<	* <li> If you override {@link setUp} or {@link tearDown}, make sure
34	>	* <li> If you override {@link #setUp} or {@link #tearDown}, make sure
35		* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within
36		* them. These methods are used to clear and check for thread
37		* assertion failures.</li>
38		*
39	<	* <li>All delays and timeouts must use one of the constants {@link
40	<	* SHORT_DELAY_MS}, {@link SMALL_DELAY_MS}, {@link MEDIUM_DELAY_MS},
41	<	* {@link LONG_DELAY_MS}. The idea here is that a SHORT is always
42	<	* discriminatable from zero time, and always allows enough time for
43	<	* the small amounts of computation (creating a thread, calling a few

41	>	* <tt> LONG_DELAY_MS</tt>. The idea here is that a SHORT is always
42	>	* discriminable from zero time, and always allows enough time for the
43	>	* small amounts of computation (creating a thread, calling a few
44		* methods, etc) needed to reach a timeout point. Similarly, a SMALL
45		* is always discriminable as larger than SHORT and smaller than
46		* MEDIUM.  And so on. These constants are set to conservative values,
47		* but even so, if there is ever any doubt, they can all be increased

48	>	* in one spot to rerun tests on slower platforms.</li>
49		*
50		* <li> All threads generated must be joined inside each test case
51		* method (or <tt>fail</tt> to do so) before returning from the
52	<	* method. The {@link joinPool} method can be used to do this when

54		*
55		* </ol>
56	+	*
57	+	* <p> <b>Other notes</b>
58	+	* <ul>
59	+	*
60	+	* <li> Usually, there is one testcase method per JSR166 method
61	+	* covering "normal" operation, and then as many exception-testing
62	+	* methods as there are exceptions the method can throw. Sometimes
63	+	* there are multiple tests per JSR166 method when the different
64	+	* "normal" behaviors differ significantly. And sometimes testcases
65	+	* cover multiple methods when they cannot be tested in
66	+	* isolation.</li>
67	+	*
68	+	* <li> The documentation style for testcases is to provide as javadoc
69	+	* a simple sentence or two describing the property that the testcase
70	+	* method purports to test. The javadocs do not say anything about how
71	+	* the property is tested. To find out, read the code.</li>
72	+	*
73	+	* <li> These tests are "conformance tests", and do not attempt to
74	+	* test throughput, latency, scalability or other performance factors
75	+	* (see the separate "jtreg" tests for a set intended to check these
76	+	* for the most central aspects of functionality.) So, most tests use
77	+	* the smallest sensible numbers of threads, collection sizes, etc
78	+	* needed to check basic conformance.</li>
79	+	*
80	+	* <li>The test classes currently do not declare inclusion in
81	+	* any particular package to simplify things for people integrating
82	+	* them in TCK test suites.</li>
83	+	*
84	+	* <li> As a convenience, the <tt>main</tt> of this class (JSR166TestCase)
85	+	* runs all JSR166 unit tests.</li>
86	+	*
87	+	* </ul>
