| /** |
| * Base JUnit <code>TestCase</code> subclass used to run independent test toward Oozie. |
| * <p/> |
| * This class provides the following functionality: |
| * <p/> |
| * <ul> |
| * <li>Creates a unique test working directory per test method on HDFS using MiniDFSCluster.</li> |
| * <li>Provides a test framework to execute tests for Oozie Workflow, Coordinator and Bundle.</li> |
| * <li>WaitFor that supports a predicate,to wait for a condition. It has timeout.</li> |
| * </ul> |
| * <p/> |
| * As part of its setup, this testcase class creates a unique test working directory per test method in the FS. |
| * <p/> |
| * The URI of the namenode can be specified via the <code>oozie.test.name.node</code> system property. The default value is |
| * 'hdfs://localhost:9000'. |
| * <p/> |
| * The test working directory is created in the specified FS URI, under the current user name home directory, under the |
| * subdirectory name specified wit the system property {@link XTestCase#OOZIE_TEST_DIR}. The default value is '/tmp'. |
| * <p/> The path of the test working directory is: '$FS_URI/user/$USER/$OOZIE_TEST_DIR/oozietest/$TEST_CASE_CLASS/ |
| * $TEST_CASE_METHOD/' |
| * <p/> For example: 'hdfs://localhost:9000/user/tucu/tmp/oozietest/org.apache.oozie.service.TestELService/testEL/' |
| * <p/> |
| * To run Oozie test, subclass create OozieClient via <code>OozieClient wc = getClient()</code> and submit Oozie job |
| * with job properties and job xml. |
| * <p/> |
| * To check job's progress, subclass retrieve job object via <code>getJobInfo()</code> and then check job's status via |
| * <code>getStatus()</code>. |
| * <p/> |
| * For example, |
| * <code> |
| * WorkflowJob wf = wc.getJobInfo(jobId);<p/> assertNotNull(wf);<p/> assertEquals(WorkflowJob.Status.PREP, wf.getStatus()); |
| * </code> |
