22 |
|
* |
23 |
|
* <ol> |
24 |
|
* |
25 |
|
* <li> All assertions in code running in generated threads must use |
26 |
< |
* the forms {@link threadFail} , {@link threadAssertTrue} {@link |
27 |
< |
* threadAssertEquals}, or {@link threadAssertNull}, (not |
26 |
> |
* the forms {@link #threadFail} , {@link #threadAssertTrue} {@link |
27 |
> |
* #threadAssertEquals}, or {@link #threadAssertNull}, (not |
28 |
|
* <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 |
|
* this way, but enough to live with.</li> |
32 |
|
* |
33 |
< |
* <li> If you override {@link setUp} or {@link tearDown}, make sure |
33 |
> |
* <li> If you override {@link #setUp} or {@link #tearDown}, make sure |
34 |
|
* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within |
35 |
|
* them. These methods are used to clear and check for thread |
36 |
|
* assertion failures.</li> |
37 |
|
* |
38 |
< |
* <li>All delays and timeouts must use one of the constants {@link |
39 |
< |
* SHORT_DELAY_MS}, {@link SMALL_DELAY_MS}, {@link MEDIUM_DELAY_MS}, |
40 |
< |
* {@link LONG_DELAY_MS}. The idea here is that a SHORT is always |
41 |
< |
* discriminatable from zero time, and always allows enough time for |
42 |
< |
* the small amounts of computation (creating a thread, calling a few |
38 |

44 |
|
* is always discriminable as larger than SHORT and smaller than |
45 |
|
* MEDIUM. And so on. These constants are set to conservative values, |
48 |
|
* |
49 |
|
* <li> All threads generated must be joined inside each test case |
50 |
|
* method (or <tt>fail</tt> to do so) before returning from the |
51 |
< |
* method. The {@link joinPool} method can be used to do this when |

52 |
|
* using Executors.</li> |

56 |
+ |
* <p> <b>Other notes</b> |
57 |
+ |
* <ul> |
58 |
+ |
* |
59 |
+ |
* <li> Usually, there is one testcase method per JSR166 method |
60 |
+ |
* covering "normal" operation, and then as many exception-testing |
61 |
+ |
* methods as there are exceptions the method can throw. Sometimes |
62 |
+ |
* there are multiple tests per JSR166 method when the different |
63 |
+ |
* "normal" behaviors differ significantly. And sometimes testcases |
64 |
+ |
* cover multiple methods when they cannot be tested in |
65 |
+ |
* isolation.</li> |
66 |
+ |
* |
67 |
+ |
* <li> The documentation style for testcases is to provide as javadoc |
68 |
+ |
* a simple sentence or two describing the property that the testcase |
69 |
+ |
* method purports to test. The javadocs do not say anything about how |
70 |
+ |
* the property is tested. To find out, read the code.</li> |
71 |
+ |
* |
72 |
+ |
* <li> These tests are "conformance tests", and do not attempt to |
73 |
+ |
* test throughput, latency, scalability or other performance factors |
74 |
+ |
* (see the separate "jtreg" tests for a set intended to check these |
75 |
+ |
* for the most central aspects of functionality.) So, most tests use |
76 |
+ |
* the smallest sensible numbers of threads, collection sizes, etc |
77 |
+ |
* needed to check basic conformance.</li> |
78 |
+ |
* |
79 |
+ |
* <li>The test classes currently do not declare inclusion in |
80 |
+ |
* any particular package to simplify things for people integrating |
81 |
+ |
* them in TCK test suites.</li> |
82 |
+ |
* |
83 |
+ |
* <li> As a convenience, the <tt>main</tt> of this class (JSR166TestCase) |
84 |
+ |
* runs all JSR166 unit tests.</li> |
