I'm new to mokito, I'm trying to test my servlet who is responsible for registering the user. I'm trying to lock up the HttpRequestServlet but I always get ClassFormException. I can not understand why. How can this be fixed, can you tell? How it is possible to properly test a servlet and to mock HttpServletRequest?
#Mock
private HttpServletRequest request = mock(HttpServletRequest.class); ;
#After
public void verifyRequest(){
verify(request).getParameter(ConstantApp.RegistrationConstantField.GET_FIRST_NAME);
verify(request).getParameter(ConstantApp.RegistrationConstantField.GET_LAST_NAME);
verify(request).getParameter(ConstantApp.RegistrationConstantField.GET_LOGIN);
verify(request).getParameter(ConstantApp.RegistrationConstantField.GET_EMAIL);
verify(request, Mockito.atLeast(2)).getParameter(ConstantApp.RegistrationConstantField.GET_PASSWORD);
verify(request).getParameter(ConstantApp.RegistrationConstantField.GET_CONFIRM_PASSWORD);
}
#Test
public void shouldReturnTrue_WhenWeGetValidField() throws Exception{
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_FIRST_NAME)).thenReturn("Aloha");
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_LAST_NAME)).thenReturn("Dance");
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_LOGIN)).thenReturn("AlohaDance123");
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_EMAIL)).thenReturn("aloha.dance#gmail.com");
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_PASSWORD)).thenReturn("12345678Aa$");
when(request.getParameter(ConstantApp.RegistrationConstantField.GET_CONFIRM_PASSWORD)).thenReturn("12345678Aa$");
Validation validation = new Validation();
Map<String, String> errorMap = validation.validate(new RegistrationInfoImpl(request));
assertTrue(errorMap.isEmpty());
}
My Exception:

im getting the below issue when i run junit test cases, the class is as follow:;
public class RoeSubmissionBeanTest {
RoeSubmissionBean roeSubmissionBean;
ServiceActivation serviceAct = new ServiceActivation();
UpdateTimeResponse updateTimeResponse = new UpdateTimeResponse();
RoEUpdateSuccessfulDT roeUpdateSucces;
MessageIdentification msgID;
ExchangeFaultData faultMessage;
#Before
public void setUp() throws Exception {
//it failes on this line
roeSubmissionBean = Mockito.mock(RoeSubmissionBean.class);
serviceAct = Mockito.mock(ServiceActivation.class);
updateTimeResponse = Mockito.mock(UpdateTimeResponse.class);
roeUpdateSucces = Mockito.mock(RoEUpdateSuccessfulDT.class);
doCallRealMethod().when(roeSubmissionBean).sendMessage(roeUpdateSucces, msgID, faultMessage);
}
and the main methods is
public class RoeSubmissionBean {
private Logger logger = LoggerFactory.getLogger(RoeSubmissionBean.class);
private JMSSender sender = new JMSSender(RoeSubmissionBean.class);
}
i tried some questions here that i have to put dependency in POM, but still getting same error

I have no problem executing this Junit (junit-4.4) of a spring 3.2.8 project from Eclipse, (Click right button -> Run As -> Junit Test)
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
public class AccomodationTypeDaoTest extends BaseDaoTest {
private AccomodationTypeDao accTypeDao;
#Test
public void testFindAll() {
assertNotNull(accTypeDao.findAll());
}
#Autowired
public void setAccomodationTypeDao(AccomodationTypeDao daoInstance) {
this.accTypeDao = daoInstance;
}
}
#SuppressWarnings("deprecation")
public class BaseDaoTest extends AbstractAnnotationAwareTransactionalTests {
private static final String[] CONFIG_LOCATIONS = new String[] { "classpath:com/dao/testDataAccessContext.xml" };
#Override
protected String[] getConfigLocations() {
return CONFIG_LOCATIONS;
}
#Test
public void testBaseDaoTest() {
assertTrue(true);
}
}
I have no problem as well, doing the same with all the classes form the package.
But when I click in the test folder /MyProject/MyProjectWeb/test/src I got this exception:

From the javadoc of BlockJUnit4ClassRunner:
/**

* #since 4.5
*/
public class BlockJUnit4ClassRunner
So it's not available in 4.4, you probably can upgrade to 4.11 without any code change

I'm trying to parse a bit of JSON in Java by following this tutorial. Because it mentions nothing about org.apache.commons.io.IOUtils other than it imports it, I figured all it was used for it to convert an InputStream into a String. I have my own code for that, so I omitted it. Here is my code:
import java.io.*;
import java.io.InputStream;
import java.net.*;
import java.util.Scanner;
import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
public class Net {
static String returnParsedIp() throws UnsupportedEncodingException, MalformedURLException, IOException {
String url = "http://httpbin.org/ip";
URLConnection connection = new URL(url).openConnection();
connection.setRequestProperty("Accept-Charset", "UTF-8");
InputStream response = connection.getInputStream();
String responseString = new Scanner(response,"UTF-8").useDelimiter("\\A").next();
//return responseString;
JSONObject json = (JSONObject) JSONSerializer.toJSON(responseString);
String Ip = json.getString("origin");
return Ip;
}
}
I then call the method from my main class with:
public class DDNS {
public static void main(String[] args) throws Exception {
String Ip = Net.returnParsedIp();
System.out.println(Ip);
}
}
However, it throws the following error:

Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)
Any help is appreciated.
Either you don't have the Apache Commons lang and io JARs in your CLASSPATH or you have the wrong version.
Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang.exception.NestableRuntimeException
This is Java 101. You need all the dependencies in the CLASSPATH in order to compile and run.
You have to add the commons-lang jar in yout project
I'm having trouble running this sample code for the gdata java library:

service.setUserCredentials("tmerachli#gmail.com", "XXX");
System.out.println("Google: " + BloggerService.getVersion());
URL feedUrl = new URL("http://minhchaunyc.blogspot.com/feeds/posts/default ");

System.out.println("service: ");

You need to add guava to your Java Build-Patproject: http://code.google.com/p/guava-libraries/
