* <li> All assertions in code running in generated threads must use |
33 |
|

34 |
|
* #threadAssertEquals}, or {@link #threadAssertNull}, (not |
35 |
< |
* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not |
35 |
> |
* {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
36 |
|
* particularly recommended) for other code to use these forms too. |
37 |
|
* Only the most typically used JUnit assertion methods are defined |
38 |
|

41 |
< |

* to invoke {@code super.setUp} and {@code super.tearDown} within |
42 |
|
