我正在为Java应用程序编写junit测试用例，这是junit测试代码

public class CultureMachineTestCases extends CultureMachineAssignment {

    CultureMachineTestCases testObj=new CultureMachineTestCases();

    @Before
    public void init() throws IOException{
        testObj.insertDataIntoSet();
        testObj.addKeywords("video1");

    }

    /*@Test
public void testVideo() throws IOException {
    result=testObj.search("abcd");
    answer=result.toString();
    answer1=answer.replaceAll("[^a-z0-9]","");

     assertEquals("video1", answer1);

}
@Before
public void initMethod() throws IOException{
    testObj.insertDataIntoSet();
    testObj.addKeywords("video2");
 }   */ @Test
  public void testLenth() throws IOException{
    flagVal=testObj.flag;

    assertEquals(1, flagVal);

    }
}

在Eclipse中运行此代码后，出现以下错误

 java.lang.StackOverflowError
    at cultureMachine.CultureMachineAssignment.<init>     (CultureMachineAssignment.java:13)
    at cultureMachine.CultureMachineTestCases.<init>(CultureMachineTestCases.java:11)

这是我的主要Java代码
