48 |
|
* <li> All assertions in code running in generated threads must use |
49 |
< |
* the forms {@link threadFail} , {@link threadAssertTrue} {@link |
50 |
< |

55 |
|
* |
56 |
< |

58 |

59 |
|

60 |
|

64 |
|

65 |
|

66 |
|
* methods, etc) needed to reach a timeout point. Similarly, a SMALL |
67 |
|
* is always discriminable as larger than SHORT and smaller than |
68 |
|
* MEDIUM. And so on. These constants are set to conservative values, |
69 |

81 |
|
* |
82 |
|
* <li> Usually, there is one testcase method per JSR166 method |
86 |
|
* "normal" behaviors differ significantly. And sometimes testcases |

89 |
< |

|
* <li> The documentation style for testcases is to provide as javadoc |
91 |
|
* a simple sentence or two describing the property that the testcase |
92 |
|
* method purports to test. The javadocs do not say anything about how |
103 |
