/**
* Base class for JSR166 Junit TCK tests. Defines some constants, utility methods and classes, as
* well as a simple framework for helping to make sure that assertions failing in generated threads
* cause the associated test that generated them to itself fail (which JUnit does not otherwise
* arrange). The rules for creating such tests are:
*
* <ol>
* <li>All assertions in code running in generated threads must use the forms {@link #threadFail},
* {@link #threadAssertTrue}, {@link #threadAssertEquals}, or {@link #threadAssertNull}, (not
* {@code fail}, {@code assertTrue}, etc.) It is OK (but not particularly recommended) for
* other code to use these forms too. Only the most typically used JUnit assertion methods are
* defined this way, but enough to live with.
* <li>If you override {@link #setUp} or {@link #tearDown}, make sure to invoke {@code
* super.setUp} and {@code super.tearDown} within them. These methods are used to clear and
* check for thread assertion failures.
* <li>All delays and timeouts must use one of the constants {@code SHORT_DELAY_MS}, {@code
* SMALL_DELAY_MS}, {@code MEDIUM_DELAY_MS}, {@code LONG_DELAY_MS}. The idea here is that a
* SHORT is always discriminable from zero time, and always allows enough time for the small
* amounts of computation (creating a thread, calling a few methods, etc) needed to reach a
* timeout point. Similarly, a SMALL is always discriminable as larger than SHORT and smaller
* than MEDIUM. And so on. These constants are set to conservative values, but even so, if
* there is ever any doubt, they can all be increased in one spot to rerun tests on slower
* platforms.
* <li>All threads generated must be joined inside each test case method (or {@code fail} to do
* so) before returning from the method. The {@code joinPool} method can be used to do this
* when using Executors.
* </ol>
*
* <p><b>Other notes</b>
*
* <ul>
* <li>Usually, there is one testcase method per JSR166 method covering "normal" operation, and
* then as many exception-testing methods as there are exceptions the method can throw.
* Sometimes there are multiple tests per JSR166 method when the different "normal" behaviors
* differ significantly. And sometimes testcases cover multiple methods when they cannot be
* tested in isolation.
* <li>The documentation style for testcases is to provide as javadoc a simple sentence or two
* describing the property that the testcase method purports to test. The javadocs do not say
* anything about how the property is tested. To find out, read the code.
* <li>These tests are "conformance tests", and do not attempt to test throughput, latency,
* scalability or other performance factors (see the separate "jtreg" tests for a set intended
* to check these for the most central aspects of functionality.) So, most tests use the
* smallest sensible numbers of threads, collection sizes, etc needed to check basic
* conformance.
* <li>The test classes currently do not declare inclusion in any particular package to simplify
* things for people integrating them in TCK test suites.
* <li>As a convenience, the {@code main} of this class (JSR166TestCase) runs all JSR166 unit
* tests.
* </ul>

/**
* Test suite for distributing JUnit3 tests. Simply add tests to this suite just like you would for
* regular JUnit3 suites, and these tests will be executed in parallel on the grid. Note that if
* there are no other grid nodes, this suite will still ensure parallel test execution within single
* JVM.
*
* <p>Below is an example of distributed JUnit3 test suite:
*
* <pre name="code" class="java">
* public class GridJunit3ExampleTestSuite {
* // Standard JUnit3 static suite method.
* public static TestSuite suite() {
* TestSuite suite = new GridJunit3TestSuite("Example Grid Test Suite");
*
* // Add tests.
* suite.addTestSuite(TestA.class);
* suite.addTestSuite(TestB.class);
* suite.addTestSuite(TestC.class);
*
* return suite;
* }
* }
* </pre>
*
* If you have four tests A, B, C, and D, and if you need to run A and B sequentially, then you
* should create a nested test suite with test A and B as follows:
*
* <pre name="code" class="java">
* public class GridJunit3ExampleTestSuite {
* // Standard JUnit3 static suite method.
* public static TestSuite suite() {
* TestSuite suite = new GridJunit3TestSuite("Example Grid Test Suite");
*
* // Nested test suite to run tests A and B sequentially.
* TestSuite nested = new TestSuite("Example Nested Sequential Suite");
*
* nested.addTestSuite(TestA.class);
* nested.addTestSuite(TestB.class);
*
* // Add tests A and B.
* suite.addTest(nested);
*
* // Add other tests.
* suite.addTestSuite(TestC.class);
*
* return suite;
* }
* }
* </pre>
*
* <p>Note that you can also grid-enable existing JUnit3 tests using {@link
* GridifyTest @GridifyTest} annotation which you can attach to your {@code suite()} methods of
* existing test suite. Refer to {@link GridifyTest @GridifyTest} documentation for more
* information.
*
* <p>Also note that some tests can only be executed locally mostly due to some environment issues.
* However they still can benefit from parallel execution with other tests. GridGain supports it via
* {@link GridJunit3LocalTestSuite} suites that can be added to {@code GridJunit3TestSuite}. Refer
* to {@link GridJunit3LocalTestSuite} documentation for more information.
*
* <h1 class="header">Logging</h1>
*
* When running distributed JUnit, all the logging that is done to {@link System#out} or {@link
* System#err} is preserved. GridGain will accumulate all logging that is done on remote nodes, send
* them back to originating node and associate all log statements with their corresponding tests.
* This way, for example, if you are running tests from and IDEA or Eclipse (or any other IDE) you
* would still see the logs as if it was a local run. However, since remote nodes keep all log
* statements done within a single individual test case in memory, you must make sure that enough
* memory is allocated on every node and that individual test cases do not spit out gigabytes of log
* statements. Also note, that logs will be sent back to originating node upon completion of every
* test, so don't be alarmed if you don't see any log statements for a while and then all of them
* appear at once.
*
* <p>GridGain achieves such log transparency via reassigning {@link System#out} or {@link
* System#err} to internal {@link PrintStream} implementation. However, when using {@code Log4J} (or
* any other logging framework) within your tests you must make sure that it is configured with
* {@link ConsoleAppender} and that {@link ConsoleAppender#setFollow(boolean)} attribute is set to
* {@code true}. Logging to files is not supported yet and is planned for next point release.
*
* <p>
*
* <h1 class="header">Test Suite Nesting</h1>
*
* {@code GridJunit3TestSuite} instances can be nested within each other as deep as needed. However
* all nested distributed test suites will be treated just like regular JUnit test suites, and not
* as distributed test suites. This approach becomes convenient when you have several distributed
* test suites that you would like to be able to execute separately in distributed fashion, but at
* the same time you would like to be able to execute them as a part of larger distributed suites.
*
* <p>
*
* <h1 class="header">Configuration</h1>
*
* To run distributed JUnit tests you need to start other instances of GridGain. You can do so by
* running {@code GRIDGAIN_HOME/bin/ggjunit.{sh|bat}} script, which will start default
* configuration. If configuration other than default is required, then use regular {@code
* GRIDGAIN_HOME/bin/ggstart.{sh|bat}} script and pass your own Spring XML configuration file as a
* parameter to the script.
*
* <p>You can use the following configuration parameters to configure distributed test suite
* locally. Note that many parameters can be overridden by setting corresponding VM parameters
* defined in {@link GridTestVmParameters} at VM startup.
*
* <table class="doctable">
* <tr>
* <th>GridConfiguration Method</th>
* <th>Default Value</th>
* <th>Description</th>
* </tr>
* <tr>
* <td>{@link #setDisabled(boolean) setDisabled(boolean)}</td>
* <td>{@code false}</td>
* <td>
* If {@code true} then GridGain will be turned off and suite will run locally.
* This value can be overridden by setting {@link GridTestVmParameters#GRIDGAIN_DISABLED} VM
* parameter to {@code true}. This parameter comes handy when you would like to
* turn off GridGain without changing the actual code.
* </td>
* </tr>
* <tr>
* <td>{@link #setConfigurationPath(String) setConfigurationPath(String)}</td>
* <td>{@link #DFLT_JUNIT_CONFIG DFLT_JUNIT_CONFIG}</td>
* <td>
* Optional path to GridGain Spring XML configuration file for running JUnit tests. This
* property can be overridden by setting {@link GridTestVmParameters#GRIDGAIN_CONFIG} VM
* parameter. Note that the value can be either absolute value or relative to
* ${GRIDGAIN_HOME} installation folder.
* </td>
* </tr>
* <tr>
* <td>{@link #setRouterClassName(String) setRouterClassName(String)}</td>
* <td>{@link #DFLT_JUNIT_ROUTER DFLT_JUNIT_ROUTER}</td>
* <td>
* Optional name of test router class that implements {@link GridTestRouter} interface.
* If not provided, then tests will be routed in round-robin fashion using default
* {@link GridTestRouterAdapter}. The value of this parameter can be overridden by setting
* {@link GridTestVmParameters#GRIDGAIN_TEST_ROUTER} VM parameter to the name of your
* own customer router class.
* </td>
* </tr>
* <tr>
* <td>{@link #setRouterClass(Class) setRouterClass(Class)}</td>
* <td>{@code null}</td>
* <td>
* Same as {@link #setRouterClassName(String) setRouterClassName(String)}, but sets the
* actual class instead of the name.
* </td>
* </tr>
* <tr>
* <td>{@link #setTimeout(long) setTimeout(long)}</td>
* <td>{@code 0} which means that tests will never timeout.</td>
* <td>
* Maximum timeout value in milliseconds after which test suite will return without
* waiting for the remaining tests to complete. This value can be overridden by setting
* {@link GridTestVmParameters#GRIDGAIN_TEST_TIMEOUT} VM parameter to the timeout value
* for the tests.
* </td>
