|
* <ol> |
25 |
|
* |
26 |
|
* <li> All assertions in code running in generated threads must use |
27 |
< |
* the forms {@link threadFail} , {@link threadAssertTrue} {@link |
28 |
< |
* threadAssertEquals}, or {@link threadAssertNull}, (not |

30 |
|
* particularly recommended) for other code to use these forms too. |
31 |
|
* Only the most typically used JUnit assertion methods are defined |
32 |
|
* this way, but enough to live with.</li> |
33 |
|
* |
34 |
< |

* to invoke {@code super.setUp} and {@code super.tearDown} within |
36 |

37 |
|

38 |
|
* |
39 |
< |
* <li>All delays and timeouts must use one of the constants {@link |
40 |
< |
* SHORT_DELAY_MS}, {@link SMALL_DELAY_MS}, {@link MEDIUM_DELAY_MS}, |
41 |
< |
* {@link LONG_DELAY_MS}. The idea here is that a SHORT is always |

57 |
+ |
* <p> <b>Other notes</b> |
58 |
+ |
* <ul> |
59 |
+ |
* |
60 |
+ |
* <li> Usually, there is one testcase method per JSR166 method |
61 |
+ |
* covering "normal" operation, and then as many exception-testing |
62 |
+ |
* methods as there are exceptions the method can throw. Sometimes |
63 |
+ |
* there are multiple tests per JSR166 method when the different |
64 |
+ |
* "normal" behaviors differ significantly. And sometimes testcases |
65 |
+ |
* cover multiple methods when they cannot be tested in |
66 |
+ |
* isolation.</li> |
67 |
+ |
* |
68 |
+ |
* <li> The documentation style for testcases is to provide as javadoc |
69 |
+ |
* a simple sentence or two describing the property that the testcase |
70 |
+ |
* method purports to test. The javadocs do not say anything about how |
71 |
+ |
* the property is tested. To find out, read the code.</li> |
72 |
+ |
* |
73 |
+ |
* <li> These tests are "conformance tests", and do not attempt to |
74 |
+ |
* test throughput, latency, scalability or other performance factors |
75 |
+ |
* (see the separate "jtreg" tests for a set intended to check these |
76 |
+ |
* for the most central aspects of functionality.) So, most tests use |
77 |
+ |
* the smallest sensible numbers of threads, collection sizes, etc |
78 |
+ |
* needed to check basic conformance.</li> |
79 |
+ |
* |
80 |
+ |
* <li>The test classes currently do not declare inclusion in |
81 |
+ |
* any particular package to simplify things for people integrating |
82 |
+ |
* them in TCK test suites.</li> |
83 |
+ |
* |
84 |
+ |
* <li> As a convenience, the {@code main} of this class (JSR166TestCase) |
85 |
+ |
* runs all JSR166 unit tests.</li> |
86 |
