How to Clean resources using teardown of junit class - junit4

Question

I am using Junit4 in eclipse.
The tests are running successfully. but at sometimes, the eclipse got hangs and closes the workspace.
And I have to deploy my code into sonar jenkins. Iam unable to do a stable build with the Junit classes.
My Junit test case goes as follows.
#RunWith(PowerMockRunner.class)
#PrepareForTest({UtilityFunctions.class,EmergencyDoDao.class,
EmergencyDoService.class,
EmergencyDoExport.class,EmergencyDoBusinessManager.class })
public class EmergencyDoServiceTest {
/**
* Run the EmergencyDoService() constructor test.
*
* #generatedBy CodePro at 9/19/13 12:00 PM
*/
#Test
public void testEmergencyDoService_1()
throws Exception {
EmergencyDoService result = new EmergencyDoService();
assertNotNull(result);
// add additional test code here
}
#Test
public void testGetEmergencyDoService_1()
throws Exception {
String dc = "5854";
String beginDate = "1/1/2011 00:00 AM";
String endDate = "9/18/2013 00:00 AM";
String doStr = "*";
String doStatus = "All";
String shipment = "*";
boolean isExport = false;
String sortBy = "CreatedDate,OrderId";
String fileType = "";
BigDecimal scheduleId = null;
BigDecimal jobId = null;
EmergencyDoInputDTO inputDto = new EmergencyDoInputDTO();
inputDto.setDc(dc);
inputDto.setBeginDate(CommonUtil.convertToSqlTimeStamp(beginDate));
inputDto.setEndDate(CommonUtil.convertToSqlTimeStamp(endDate));
inputDto.setDoStr(doStr);
inputDto.setDoStatus(doStatus);
inputDto.setShipment(shipment);
inputDto.setSortBy(sortBy);
inputDto.setExport(isExport);
inputDto.setFileType(fileType);
EmergencyDoMockDAO.mockgetEmergencyDo(inputDto,scheduleId,jobId);
Response result = EmergencyDoService.getEmergencyDoService(dc, beginDate, endDate, doStr, doStatus, shipment, isExport, sortBy, fileType, scheduleId, jobId);
String output = result.getEntity().toString();
Assert.assertEquals(true,output.contains("\"result\": \"Success\""));
}
#Before
public void setUp()
throws Exception {
// add additional set up code here
}
/**
* Perform post-test clean-up.
*
* #throws Exception
* if the clean-up fails for some reason
*
* #generatedBy CodePro at 9/19/13 12:00 PM
*/
#After
public void tearDown()
throws Exception {
// Add additional tear down code here
}
/**
* Launch the test.
*
* #param args the command line arguments
*
* #generatedBy CodePro at 9/19/13 12:00 PM
*/
public static void main(String[] args) {
new org.junit.runner.JUnitCore().run(EmergencyDoServiceTest.class);
}
After lot of struggling, I found that in the teardown of junit class, we can add code to clean the resources.
Can anybody suggest me how to clean the above resources in Junit, so that I can have a stable bulid in jenkins.

Answer 1

I don't see any suspicious code that can possibly block and/or close Eclipse. IIRC setUp() and tearDown() was to init/clean up unit test resources in Junit3. In JUnit 4, it totally depends on #Before and #After annotations.
And can I ask what do you mean "Iam unable to do a stable build with the Junit classes"? If it's unstable build with JUnit classes, that's probably your unit test is broken. Either fixing broken unit test or just disable/delete them(if you don't think those unit tests are useful) would allow you to build stable build.
