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 |
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 |
195 |
