120 < * <li>All assertions in code running in generated threads must use
121 < * the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
122 < * #threadAssertEquals}, or {@link #threadAssertNull}, (not
123 < * {@code fail}, {@code assertTrue}, etc.) It is OK (but not
124 < * particularly recommended) for other code to use these forms too.
125 < * Only the most typically used JUnit assertion methods are defined
126 < * this way, but enough to live with.
120 > * <li>All code not running in the main test thread (manually spawned threads
121 > * or the common fork join pool) must be checked for failure (and completion!).
122 > * Mechanisms that can be used to ensure this are:
123 > *   <ol>
124 > *   <li>Signalling via a synchronizer like AtomicInteger or CountDownLatch
125 > *    that the task completed normally, which is checked before returning from
126 > *    the test method in the main thread.
127 > *   <li>Using the forms {@link #threadFail}, {@link #threadAssertTrue},
128 > *    or {@link #threadAssertNull}, (not {@code fail}, {@code assertTrue}, etc.)
129 > *    Only the most typically used JUnit assertion methods are defined
130 > *    this way, but enough to live with.
131 > *   <li>Recording failure explicitly using {@link #threadUnexpectedException}
132 > *    or {@link #threadRecordFailure}.
133 > *   <li>Using a wrapper like CheckedRunnable that uses one the mechanisms above.
134 > *   </ol>
