|
* Base class for JSR166 Junit TCK tests. Defines some constants, |
118 |
|
* |
119 |
|
* <ol> |
120 |
|
* |
121 |
< |
* <li> All assertions in code running in generated threads must use |
122 |
< |
* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link |
123 |
< |
* #threadAssertEquals}, or {@link #threadAssertNull}, (not |
124 |
< |
* {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
125 |
< |
* particularly recommended) for other code to use these forms too. |
126 |
< |
* Only the most typically used JUnit assertion methods are defined |
127 |
< |
* this way, but enough to live with.</li> |
121 |
> |
* <li>All code not running in the main test thread (manually spawned threads |
122 |
> |
* or the common fork join pool) must be checked for failure (and completion!). |
123 |
> |
* Mechanisms that can be used to ensure this are: |
124 |
> |
* <ol> |
125 |
> |
* <li>Signalling via a synchronizer like AtomicInteger or CountDownLatch |
126 |
> |
* that the task completed normally, which is checked before returning from |
127 |
> |
* the test method in the main thread. |
128 |
> |
* <li>Using the forms {@link #threadFail}, {@link #threadAssertTrue}, |
129 |
> |
* or {@link #threadAssertNull}, (not {@code fail}, {@code assertTrue}, etc.) |
130 |
> |
* Only the most typically used JUnit assertion methods are defined |
131 |
> |
* this way, but enough to live with. |
132 |
> |
* <li>Recording failure explicitly using {@link #threadUnexpectedException} |
133 |
> |
* or {@link #threadRecordFailure}. |
134 |
> |
* <li>Using a wrapper like CheckedRunnable that uses one the mechanisms above. |
135 |
> |
* </ol> |
136 |

137 |
< |
* <li> If you override {@link #setUp} or {@link #tearDown}, make sure |
137 |
> |
* <li>If you override {@link #setUp} or {@link #tearDown}, make sure |
138 |
|
* to invoke {@code super.setUp} and {@code super.tearDown} within |
139 |
|
* them. These methods are used to clear and check for thread |
140 |
< |
* assertion failures.</li> |

143 |
|
* SHORT_DELAY_MS}, {@code SMALL_DELAY_MS}, {@code MEDIUM_DELAY_MS}, |
148 |
|
* is always discriminable as larger than SHORT and smaller than |
149 |
|
* MEDIUM. And so on. These constants are set to conservative values, |
150 |
|
* but even so, if there is ever any doubt, they can all be increased |
151 |
< |
* in one spot to rerun tests on slower platforms.</li> |
