I'm trying to debug unit tests in eclipse IDE, There is no any issue in addPlatform() method in line 292. but when I'm debugging the test case, it gives following error without hitting first line of addPlatform() method. PSMDataManager.class file is created and its in right location
Please give me a suggestion to avoid this exception.
public static boolean addPlatform(String platformName, String accountId, String accountDn) {
try {
ManagePSMData bean = getPSMDataStoreBean();
boolean success = false;
success = bean.addPlatform(platformName, accountId, accountDn);
return success;
} catch (RemoteException e) {
log.info("Error while adding an Platform " + platformName
+ " platform already exists");
return false;
}
}
java.lang.Error: Unresolved compilation problem:

What do I wrong?
If to remove following row:
whenNew(StringWriter.class).withNoArguments().thenReturn(stringWriterMock);
code becomes working...
What the magic?
The exception is thrown when the static initializer of IOUtils is executed, which looks like this (version 2.4):
static {
// avoid security issues
StringBuilderWriter buf = new StringBuilderWriter(4);
PrintWriter out = new PrintWriter(buf); //<-- kaboom here
out.println();
LINE_SEPARATOR = buf.toString();
out.close();
}
The NullPointerException is thrown down the stack while invoking new PrintWriter(buf) because the parameter (buf) is null.
I suspect your remaining test code modifies the code so that buf is assigned a value of null. Did you mock the Constructor of StringBuilderWriter for some reason?
I am trying to mock a private method and verify it has been executed.
The mocking itself works fine, that is I am getting correct results whether I comment/uncomment the 'when' line. However, I am having troubles with verification.
#RunWith(PowerMockRunner.class)
#PrepareForTest(ClassToTest.class)
public class TestClass {
#Test
public void test() throws Exception {
ClassToTest spy = PowerMockito.spy(new ClassToTest());
when(spy, method(ClassToTest.class, "privMethod", int.class)).withArguments(anyInt()).thenReturn(20);
System.out.println(spy.pubMethod());
PowerMockito.verifyPrivate(spy, times(1)).invoke("privMethod", int.class);
}
}
class ClassToTest {
public int pubMethod() {
return privMethod(231);
}
private int privMethod(int whatever) {
return 10;
}
}
created this example based on https://code.google.com/p/powermock/wiki/MockitoUsage13
This is what I am getting, any idea why?

Instead of int.class, verify the argument value 231. Mock verification works by matching values, not types (unless you use the argument matchers as in your when part).
http://localhost:8080/solr works well in my browser and there is no error in the console of tomcat when I start it.
my code is：
public static void index() throws SolrServerException, IOException {

HttpSolrServer server = new HttpSolrServer(url);
SolrInputDocument doc = new SolrInputDocument();
doc.addField("id", "1");
doc.addField("name", "name");
doc.addField("content", "cold today");
server.add(doc);
server.commit();
}
when I run the code,there is nothing printed in the console of tomcat and I get

I think here is something wrong in my computer but I can not figure out.
I have tried solr 4.6.0 and solr 4.7.2,both of them failed.
It fails when running this code：
final HttpResponse response = httpClient.execute(method);
in HttpSolrServer.java(line number 395 in 4.7.2)
But when I copied the project to my roommate's computer ,it worked fine.
It's very wierd.It seems that the request is successfully accepted by server and if I change my code like：
public static void index() throws SolrServerException, IOException {
String url = "http://localhost:8080/solr";
HttpSolrServer server = new HttpSolrServer(url);
server.setSoTimeout(10000);
SolrInputDocument doc = new SolrInputDocument();
doc.addField("id", "3");
doc.addField("name", "name3");
doc.addField("content", "cold today3");
try{
server.add(doc);
}catch(Exception e){
e.printStackTrace(); //time out
}
server.commit();
}
It still prints exception message but it works...
I have three classes- class 'ABC' 'PQR' and 'XYZ'

class PQR
public static Long getExistingGroupId() throws Exception {
Long GrpId;
List<MsecBusGroups> busGroupsList = new ArrayList<MsecBusGroups>();
busGroupsList=XYZ.getBusGroups();
if (busGroupsList!=null){
MsecBusGroups It1=busGroupsList.get(busGroupsList.size()-1);
GrpId=It1.getId();
return GrpId;
} else {
throw new Exception("BUSINESS GROUPS LIST RETURNED IS NULL");
}
}
class XYZ
public List<MsecBusGroups> getBusGroups() throws PersistenceException {
final String METHOD_NAME = "getBusGroups()";
LogHelper.logEntry(CLASS_NAME, METHOD_NAME);
List<MsecBusGroups> list = null;
try {
Query q = em.createNamedQuery("getBusGroups");
list = q.getResultList();
if (list == null) {
LogHelper.debug(CLASS_NAME, METHOD_NAME, "No Record Found");
}
...
}
When I run the test method in ABC class its throwing java.lang.NullPointerException.
