43	>	* tests are:
44		*
45		* <ol>
46		*
47		* <li> All assertions in code running in generated threads must use
48	<	* the forms {@link threadFail} , {@link threadAssertTrue} {@link
49	<	* threadAssertEquals}, or {@link threadAssertNull}, (not
50	<	* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not
48	>	* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
49	>	* #threadAssertEquals}, or {@link #threadAssertNull}, (not
50	>	* {@code fail}, {@code assertTrue}, etc.) It is OK (but not
51		* particularly recommended) for other code to use these forms too.
52		* Only the most typically used JUnit assertion methods are defined
53		* this way, but enough to live with.</li>
54		*
55	<	* <li> If you override {@link setUp} or {@link tearDown}, make sure
56	<	* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within
55	>	* <li> If you override {@link #setUp} or {@link #tearDown}, make sure
56	>	* to invoke {@code super.setUp} and {@code super.tearDown} within
57		* them. These methods are used to clear and check for thread
58		* assertion failures.</li>
59		*
60	<	* <li>All delays and timeouts must use one of the constants {@link
61	<	* SHORT_DELAY_MS}, {@link SMALL_DELAY_MS}, {@link MEDIUM_DELAY_MS},
62	<	* {@link LONG_DELAY_MS}. The idea here is that a SHORT is always
63	<	* discriminatable from zero time, and always allows enough time for
64	<	* the small amounts of computation (creating a thread, calling a few

65		* methods, etc) needed to reach a timeout point. Similarly, a SMALL
66		* is always discriminable as larger than SHORT and smaller than
67		* MEDIUM.  And so on. These constants are set to conservative values,
68	<	* (100, 500, 1000, 5000 MS) but even so, if there is ever any doubt,
69	<	* they can all be increased in one spot to rerun tests on slower

70		*
71		* <li> All threads generated must be joined inside each test case
72	<	* method (or <tt>fail</tt> to do so) before returning from the
73	<	* method. The {@link joinPool} method can be used to do this when

76		* </ol>
77	+	*
78	+	* <p><b>Other notes</b>
79	+	* <ul>
80	+	*
81	+	* <li> Usually, there is one testcase method per JSR166 method
82	+	* covering "normal" operation, and then as many exception-testing
83	+	* methods as there are exceptions the method can throw. Sometimes
84	+	* there are multiple tests per JSR166 method when the different
85	+	* "normal" behaviors differ significantly. And sometimes testcases
86	+	* cover multiple methods when they cannot be tested in
87	+	* isolation.</li>
88	+	*
89	+	* <li> The documentation style for testcases is to provide as javadoc
90	+	* a simple sentence or two describing the property that the testcase
91	+	* method purports to test. The javadocs do not say anything about how
92	+	* the property is tested. To find out, read the code.</li>
93	+	*
94	+	* <li> These tests are "conformance tests", and do not attempt to
95	+	* test throughput, latency, scalability or other performance factors
96	+	* (see the separate "jtreg" tests for a set intended to check these
97	+	* for the most central aspects of functionality.) So, most tests use
98	+	* the smallest sensible numbers of threads, collection sizes, etc
99	+	* needed to check basic conformance.</li>
100	+	*
101	+	* <li>The test classes currently do not declare inclusion in
102	+	* any particular package to simplify things for people integrating
103	+	* them in TCK test suites.</li>
104	+	*
105	+	* <li> As a convenience, the {@code main} of this class (JSR166TestCase)
106	+	* runs all JSR166 unit tests.</li>
