122	<	* <li>All assertions in code running in generated threads must use
123	<	* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
124	<	* #threadAssertEquals}, or {@link #threadAssertNull}, (not
125	<	* {@code fail}, {@code assertTrue}, etc.) It is OK (but not
126	<	* particularly recommended) for other code to use these forms too.
127	<	* Only the most typically used JUnit assertion methods are defined
128	<	* this way, but enough to live with.
122	>	* <li>All code not running in the main test thread (manually spawned threads
123	>	* or the common fork join pool) must be checked for failure (and completion!).
124	>	* Mechanisms that can be used to ensure this are:
125	>	*   <ol>
126	>	*   <li>Signalling via a synchronizer like AtomicInteger or CountDownLatch
127	>	*    that the task completed normally, which is checked before returning from
128	>	*    the test method in the main thread.
129	>	*   <li>Using the forms {@link #threadFail}, {@link #threadAssertTrue},
130	>	*    or {@link #threadAssertNull}, (not {@code fail}, {@code assertTrue}, etc.)
131	>	*    Only the most typically used JUnit assertion methods are defined
132	>	*    this way, but enough to live with.
133	>	*   <li>Recording failure explicitly using {@link #threadUnexpectedException}
134	>	*    or {@link #threadRecordFailure}.
135	>	*   <li>Using a wrapper like CheckedRunnable that uses one the mechanisms above.
136	>	*   </ol>
137		*
138		* <li>If you override {@link #setUp} or {@link #tearDown}, make sure
139		* to invoke {@code super.setUp} and {@code super.tearDown} within
#	Line 104 | Line 151 | import junit.framework.TestSuite;
151		* but even so, if there is ever any doubt, they can all be increased
152		* in one spot to rerun tests on slower platforms.
153		*
154	+	* Class Item is used for elements of collections and related
155	+	* purposes. Many tests rely on their keys being equal to ints. To
156	+	* check these, methods mustEqual, mustContain, etc adapt the JUnit
157	+	* assert methods to intercept ints.
158	+	*
159		* <li>All threads generated must be joined inside each test case
160		* method (or {@code fail} to do so) before returning from the
161		* method. The {@code joinPool} method can be used to do this when
