| 66 | * Base class for JSR166 Junit TCK tests. Defines some constants, |
| 67 | * utility methods and classes, as well as a simple framework for |
| 68 | * helping to make sure that assertions failing in generated threads |
| 69 | * cause the associated test that generated them to itself fail (which |
| 70 | * JUnit does not otherwise arrange). The rules for creating such |
| 71 | * tests are: |
| 72 | * |
| 73 | * <ol> |
| 74 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 75 | * <li>All assertions in code running in generated threads must use |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 76 | * the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link |
| 77 | * #threadAssertEquals}, or {@link #threadAssertNull}, (not |
| 78 | * {@code fail}, {@code assertTrue}, etc.) It is OK (but not |
| 79 | * particularly recommended) for other code to use these forms too. |
| 80 | * Only the most typically used JUnit assertion methods are defined |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 81 | * this way, but enough to live with. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 82 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 83 | * <li>If you override {@link #setUp} or {@link #tearDown}, make sure |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 84 | * to invoke {@code super.setUp} and {@code super.tearDown} within |
| 85 | * them. These methods are used to clear and check for thread |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 86 | * assertion failures. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 87 | * |
| 88 | * <li>All delays and timeouts must use one of the constants {@code |
| 89 | * SHORT_DELAY_MS}, {@code SMALL_DELAY_MS}, {@code MEDIUM_DELAY_MS}, |
| 90 | * {@code LONG_DELAY_MS}. The idea here is that a SHORT is always |
| 91 | * discriminable from zero time, and always allows enough time for the |
| 92 | * small amounts of computation (creating a thread, calling a few |
| 93 | * methods, etc) needed to reach a timeout point. Similarly, a SMALL |
| 94 | * is always discriminable as larger than SHORT and smaller than |
| 95 | * MEDIUM. And so on. These constants are set to conservative values, |
| 96 | * but even so, if there is ever any doubt, they can all be increased |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 97 | * in one spot to rerun tests on slower platforms. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 98 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 99 | * <li>All threads generated must be joined inside each test case |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 100 | * method (or {@code fail} to do so) before returning from the |
| 101 | * method. The {@code joinPool} method can be used to do this when |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 102 | * using Executors. |

| 105 | * |
| 106 | * <p><b>Other notes</b> |
| 107 | * <ul> |
| 108 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 109 | * <li>Usually, there is one testcase method per JSR166 method |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 110 | * covering "normal" operation, and then as many exception-testing |
| 111 | * methods as there are exceptions the method can throw. Sometimes |
| 112 | * there are multiple tests per JSR166 method when the different |
| 113 | * "normal" behaviors differ significantly. And sometimes testcases |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 114 | * cover multiple methods when they cannot be tested in isolation. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 115 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 116 | * <li>The documentation style for testcases is to provide as javadoc |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 117 | * a simple sentence or two describing the property that the testcase |
| 118 | * method purports to test. The javadocs do not say anything about how |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 119 | * the property is tested. To find out, read the code. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 120 | * |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 121 | * <li>These tests are "conformance tests", and do not attempt to |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 122 | * test throughput, latency, scalability or other performance factors |
| 123 | * (see the separate "jtreg" tests for a set intended to check these |
| 124 | * for the most central aspects of functionality.) So, most tests use |
| 125 | * the smallest sensible numbers of threads, collection sizes, etc |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 126 | * needed to check basic conformance. |
Calin Juravle | 8f0d92b | 2013-08-01 17:26:00 +0100 | [diff] [blame] | 127 | * |
| 128 | * <li>The test classes currently do not declare inclusion in |
| 129 | * any particular package to simplify things for people integrating |
Przemyslaw Szczepaniak | b8b7511 | 2016-03-11 15:59:10 +0000 | [diff] [blame] | 130 | * them in TCK test suites. |
