/** |
15 |
dl |
1.5 |
* Base class for JSR166 Junit TCK tests. Defines some constants, |
16 |
|
|
* utility methods and classes, as well as a simple framework for |
17 |
|
|
* helping to make sure that assertions failing in generated threads |
18 |
|
|
* cause the associated test that generated them to itself fail (which |
19 |
|
|
* JUnit doe not otherwise arrange). The rules for creating such |
20 |
|
|
* tests are: |
21 |
dl |
1.1 |
* |
22 |
|
|
* <ol> |
23 |
|
|
* |
24 |
|
|
* <li> All assertions in code running in generated threads must use |
25 |
|
|
* the forms {@link threadFail} , {@link threadAssertTrue} {@link |
26 |
|
|
* threadAssertEquals}, or {@link threadAssertNull}, (not |
27 |
|
|
* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not |
28 |
|
|
* particularly recommended) for other code to use these forms too. |
29 |
|
|
* Only the most typically used JUnit assertion methods are defined |
30 |
|
|
* this way, but enough to live with.</li> |
31 |
|
|
* |
32 |
|
|
* <li> If you override {@link setUp} or {@link tearDown}, make sure |
33 |
|
|
* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within |
34 |
|
|
* them. These methods are used to clear and check for thread |
35 |
|
|
* assertion failures.</li> |
36 |
|
|
* |
37 |
dl |
1.6 |
* <li>All delays and timeouts must use one of the constants <tt> |
38 |
|
|
* SHORT_DELAY_MS</tt>, <tt> SMALL_DELAY_MS</tt>, <tt> MEDIUM_DELAY_MS</tt>, |
39 |
|
|
* <tt> LONG_DELAY_MS</tt>. The idea here is that a SHORT is always |
40 |
dl |
1.5 |
* discriminable from zero time, and always allows enough time for the |
41 |
|
|
* small amounts of computation (creating a thread, calling a few |
42 |
dl |
1.1 |
* methods, etc) needed to reach a timeout point. Similarly, a SMALL |
43 |
|
|
* is always discriminable as larger than SHORT and smaller than |
44 |
|
|
* MEDIUM. And so on. These constants are set to conservative values, |
45 |
dl |
1.2 |
* but even so, if there is ever any doubt, they can all be increased |
46 |
|
|
* in one spot to rerun tests on slower platforms</li> |
47 |
dl |
1.1 |
* |
48 |
|
|
* <li> All threads generated must be joined inside each test case |
49 |
|
|
* method (or <tt>fail</tt> to do so) before returning from the |
50 |
dl |
1.6 |
* method. The <tt> joinPool</tt> method can be used to do this when |
51 |
dl |
1.1 |
* using Executors.</li> |
52 |
|
|
* |
53 |
|
|
* </ol> |
54 |
dl |
1.6 |
* |
55 |
|
|
* <p> <b>Other notes</b> |
56 |
|
|
* <ul> |
57 |
|
|
* |
58 |
|
|
* <li> Usually, there is one testcase method per JSR166 method |
59 |
|
|
* covering "normal" operation, and then as many exception-testing |
60 |
|
|
* methods as there are exceptions the method can throw. Sometimes |
61 |
|
|
* there are multiple tests per JSR166 method when the different |
62 |
|
|
* "normal" behaviors differ significantly. And sometimes testcases |
63 |
|
|
* cover multiple methods when they cannot be tested in |
64 |
|
|
* isolation.</li> |
65 |
|
|
* |
66 |
|
|
* <li> The documentation style for testcases is to provide as javadoc |
67 |
|
|
* a simple sentence or two describing the property that the testcase |
68 |
|
|
* method purports to test. The javadocs do not say anything about how |
69 |
|
|
* the property is tested. To find out, read the code.</li> |
70 |
|
|
* |
71 |
|
|
* <li> These tests are "conformance tests", and do not attempt to |
72 |
|
|
* test throughput, latency, scalability or other performance factors |
73 |
|
|
* (see the separate "jtreg" tests for a set intended to check these |
74 |
|
|
* for the most central aspects of functionality.) So, most tests use |
75 |
|
|
* the smallest sensible numbers of threads, collection sizes, etc |
76 |
|
|
* needed to check basic conformance.</li> |
77 |
|
|
* |
78 |
|
|
* <li>The test classes currently do not declare inclusion in |
79 |
|
|
* any particular package to simplify things for people integrating |
80 |
|
|
* them in TCK test suites.</li> |
81 |
|
|
* |
82 |
|
|
* <li> As a convenience, the <tt>main</tt> of this class (JSR166TestCase) |
83 |
|
|
* runs all JSR166 unit tests.</li> |
84 |
|
|
