1.5 |
* Base class for JSR166 Junit TCK tests. Defines some constants, |
84 |
|
|
* utility methods and classes, as well as a simple framework for |
85 |
|
|
* helping to make sure that assertions failing in generated threads |
86 |
|
|
* cause the associated test that generated them to itself fail (which |
87 |
jsr166 |
1.27 |
* JUnit does not otherwise arrange). The rules for creating such |
88 |
dl |
1.5 |
* tests are: |
89 |
dl |
1.1 |
* |
90 |
|
|
* <ol> |
91 |
|
|
* |
92 |
jsr166 |
1.143 |
* <li>All assertions in code running in generated threads must use |
93 |
jsr166 |
1.27 |
* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link |
94 |
dl |
1.18 |
* #threadAssertEquals}, or {@link #threadAssertNull}, (not |
95 |
jsr166 |
1.50 |
* {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
96 |
dl |
1.1 |
* particularly recommended) for other code to use these forms too. |
97 |
|
|
* Only the most typically used JUnit assertion methods are defined |
98 |
jsr166 |
1.143 |
* this way, but enough to live with. |
99 |
dl |
1.1 |
* |
100 |
jsr166 |
1.143 |
* <li>If you override {@link #setUp} or {@link #tearDown}, make sure |
101 |
jsr166 |
1.50 |
* to invoke {@code super.setUp} and {@code super.tearDown} within |
102 |
dl |
1.1 |
* them. These methods are used to clear and check for thread |
103 |
jsr166 |
1.143 |
* assertion failures. |
104 |
dl |
1.1 |
* |
105 |
jsr166 |
1.51 |
* <li>All delays and timeouts must use one of the constants {@code |
106 |
jsr166 |
1.50 |
* SHORT_DELAY_MS}, {@code SMALL_DELAY_MS}, {@code MEDIUM_DELAY_MS}, |
107 |
|
|
* {@code LONG_DELAY_MS}. The idea here is that a SHORT is always |
108 |
dl |
1.5 |
* discriminable from zero time, and always allows enough time for the |
109 |
|
|
* small amounts of computation (creating a thread, calling a few |
110 |
dl |
1.1 |
* methods, etc) needed to reach a timeout point. Similarly, a SMALL |
111 |
|
|
* is always discriminable as larger than SHORT and smaller than |
112 |
|
|
* MEDIUM. And so on. These constants are set to conservative values, |
113 |
dl |
1.2 |
* but even so, if there is ever any doubt, they can all be increased |
114 |
jsr166 |
1.143 |
* in one spot to rerun tests on slower platforms. |
115 |
dl |
1.1 |
* |
116 |
jsr166 |
1.143 |
* <li>All threads generated must be joined inside each test case |
117 |
jsr166 |
1.50 |
* method (or {@code fail} to do so) before returning from the |
118 |
|
|
* method. The {@code joinPool} method can be used to do this when |
119 |
jsr166 |
1.143 |
* using Executors. |
120 |
dl |
1.1 |

* <p><b>Other notes</b> |
124 |
dl |
1.6 |
* <ul> |
125 |
|
|
* |
126 |
jsr166 |
1.143 |
* <li>Usually, there is one testcase method per JSR166 method |
127 |
dl |
1.6 |
* covering "normal" operation, and then as many exception-testing |
128 |
|
|
* methods as there are exceptions the method can throw. Sometimes |
129 |
|
|
* there are multiple tests per JSR166 method when the different |
130 |
|
|
* "normal" behaviors differ significantly. And sometimes testcases |
131 |
jsr166 |
1.180 |
* cover multiple methods when they cannot be tested in isolation. |
132 |
jsr166 |
1.27 |
* |
133 |
jsr166 |
1.143 |
* <li>The documentation style for testcases is to provide as javadoc |
134 |
dl |
1.6 |
* a simple sentence or two describing the property that the testcase |
135 |
|
|
* method purports to test. The javadocs do not say anything about how |
136 |
jsr166 |
1.143 |
* the property is tested. To find out, read the code. |
137 |
dl |
1.6 |
* |
138 |
jsr166 |
1.143 |
* <li>These tests are "conformance tests", and do not attempt to |
139 |
dl |
1.6 |
* test throughput, latency, scalability or other performance factors |
140 |
|
|
* (see the separate "jtreg" tests for a set intended to check these |
141 |
|
|
* for the most central aspects of functionality.) So, most tests use |
142 |
|
|
* the smallest sensible numbers of threads, collection sizes, etc |
143 |
jsr166 |
1.143 |
* needed to check basic conformance. |
144 |
dl |
1.6 |
* |
145 |
|
|
* <li>The test classes currently do not declare inclusion in |
146 |
|
|
* any particular package to simplify things for people integrating |
147 |
jsr166 |
1.143 |
* them in TCK test suites. |
148 |
dl |
1.6 |
* |
149 |
jsr166 |
1.143 |
* <li>As a convenience, the {@code main} of this class (JSR166TestCase) |
150 |
|
|
* runs all JSR166 unit tests. |
151 |
dl |
