25 |

* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not |
29 |
|
* particularly recommended) for other code to use these forms too. |
30 |
|
* Only the most typically used JUnit assertion methods are defined |
31 |

36 |
|
* assertion failures.</li> |

* is always discriminable as larger than SHORT and smaller than |
45 |
|
