* |
46 |
|
* <ol> |
47 |
|
* |
48 |
|
* <li> All assertions in code running in generated threads must use |
49 |
< |
* the forms {@link threadFail} , {@link threadAssertTrue} {@link |
50 |
< |
* threadAssertEquals}, or {@link threadAssertNull}, (not |
51 |
< |

51 |

* {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
52 |
|
* particularly recommended) for other code to use these forms too. |
53 |
|
* Only the most typically used JUnit assertion methods are defined |
54 |
|
* this way, but enough to live with.</li> |
55 |
|
* |
56 |
< |
* <li> If you override {@link setUp} or {@link tearDown}, make sure |
57 |
< |

57 |

* to invoke {@code super.setUp} and {@code super.tearDown} within |
58 |
|
* them. These methods are used to clear and check for thread |
59 |
|
* assertion failures.</li> |
60 |
|
* |
61 |
< |
* <li>All delays and timeouts must use one of the constants {@link |
62 |
< |
* SHORT_DELAY_MS}, {@link SMALL_DELAY_MS}, {@link MEDIUM_DELAY_MS}, |
63 |
< |
* {@link LONG_DELAY_MS}. The idea here is that a SHORT is always |
64 |
< |
* discriminatable from zero time, and always allows enough time for |

|

68 |

69 |
|

+ |
* <p><b>Other notes</b> |
80 |
+ |
* <ul> |
81 |
+ |
* |
82 |
+ |
* <li> Usually, there is one testcase method per JSR166 method |
83 |
+ |
* covering "normal" operation, and then as many exception-testing |
84 |
+ |
* methods as there are exceptions the method can throw. Sometimes |
85 |
+ |
* there are multiple tests per JSR166 method when the different |
86 |
+ |
* "normal" behaviors differ significantly. And sometimes testcases |
87 |
+ |
* cover multiple methods when they cannot be tested in |
88 |
+ |
* isolation.</li> |
89 |
+ |
* |
90 |
+ |
* <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 |
93 |
+ |
* the property is tested. To find out, read the code.</li> |
94 |
+ |
* |
95 |
+ |
* <li> These tests are "conformance tests", and do not attempt to |
96 |
+ |
* test throughput, latency, scalability or other performance factors |
97 |
+ |
* (see the separate "jtreg" tests for a set intended to check these |
98 |
+ |
* for the most central aspects of functionality.) So, most tests use |
99 |
+ |
* the smallest sensible numbers of threads, collection sizes, etc |
100 |
+ |
* needed to check basic conformance.</li> |
101 |
+ |
* |
102 |
+ |
* <li>The test classes currently do not declare inclusion in |
103 |
+ |
* any particular package to simplify things for people integrating |
104 |
+ |
* them in TCK test suites.</li> |
105 |
+ |
* |
106 |
+ |
* <li> As a convenience, the {@code main} of this class (JSR166TestCase) |
107 |
+ |
* runs all JSR166 unit tests.</li> |
108 |
+ |
* |
