|
* Base class for JSR166 Junit TCK tests. Defines some constants, |
35 |
|
* <li> All assertions in code running in generated threads must use |
36 |
|
* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link |
37 |
|
* #threadAssertEquals}, or {@link #threadAssertNull}, (not |
38 |
< |
* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not |
38 |
> |
* {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
39 |
|
* particularly recommended) for other code to use these forms too. |
40 |
|
* Only the most typically used JUnit assertion methods are defined |
41 |
|
* this way, but enough to live with.</li> |
42 |
|
* |
43 |
|
* <li> If you override {@link #setUp} or {@link #tearDown}, make sure |
44 |
< |
* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within |
44 |
> |
* to invoke {@code super.setUp} and {@code super.tearDown} within |
45 |
|
* them. These methods are used to clear and check for thread |
46 |
|
* assertion failures.</li> |
47 |

* <li>All delays and timeouts must use one of the constants <tt> |

< |
* SHORT_DELAY_MS</tt>, <tt> SMALL_DELAY_MS</tt>, <tt> MEDIUM_DELAY_MS</tt>, |
50 |

53 |
|
