Hi Lipeng, Note that Surefire only picks up tests that match the following:
By default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns: - "**/Test*.java" - includes all of its subdirectories and all Java filenames that start with "Test". - "**/*Test.java" - includes all of its subdirectories and all Java filenames that end with "Test". - "**/*TestCase.java" - includes all of its subdirectories and all Java filenames that end with "TestCase". http://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html Try adding a new test file (in the appropriate test dir) called TestMiniDFSClusterManager with your test code.
