etup(){
dordao.exampleservice(mock(exampleservice.class));
}

@Test
public void exampl(){
..
.
.
.
when(dordao.exampleservice.process(any(request.cla ss),any(RequestHeaderT.class),(Holder<ResponseHead erT>) any()).thenreturn(response));

List<String> lst=exampleservice.example();
//example will return list of strings
.

Stack trace?
Full exception text?
Line the exception is thrown from?

[acmohan]

It points to "when" statement.

error:java.lang.NullPointerException

[acmohan]

one more error "java.lang.IllegalStateException: no last call on a mock available" below is the code.

@Test
public void testGetis() {
ServiceProcessResponse response = new ServiceProcessResponse();

response.setStatus("S");
response.setError(null);
ServiceProcessRequest request=new ServiceProcessRequest();
request.setEmailAddress("11");
request.setOrderNumber("123");
expect(DaoImpl.getService().process(
request, null, null)).andReturn(response);
replay(promotionDaoImpl);
DaoImpl.data(anyString(),anyBoolean(), anyBoolean());
verify(DaoImpl);
}
i am getting error at "when" statement line.

here when i say return(response) ,it s returning null instead of what i have defined.

can any one help on this please.

[Tolls]

There were three questions up there. Stack trace?

And can you please post your code in code tags:

@Test
	public void testGetis() {
		ServiceProcessResponse response = new ServiceProcessResponse();
		
		response.setStatus("S");
		response.setError(null);
		ServiceProcessRequest request=new ServiceProcessRequest();
		request.setEmailAddress("11");
		request.setOrderNumber("123");
		expect(DaoImpl.getService().process(
				request, null, null)).andReturn(response);
		replay(promotionDaoImpl);
		DaoImpl.data(anyString(),anyBoolean(), anyBoolean());
		verify(DaoImpl);
	}

Focus on one error at a time.
What mocking framework are you using?
How are you setting up the mocked objects?
How are you injecting them into the class you are testing?

[acmohan]

i am using mockito.

AdaoImpl DaoImpl;
@Before
public void setUp(){
DaoImpl=new AdaoImpl();
DaoImpl.setService(mock(Service.class));
}

expect(DaoImpl.getService().process(
request, null, null)).andReturn(response);

One last try and them I'm out of here...
STACK TRACE?

[acmohan]

I am really sorry for it. My sts got crashed.
let me explain to u .
when i run above test case in debug mode,
when "DaoImpl.getService().process(request, null, null).andReturn(response) " calls ( wat we mean s when we call getService.process just return us response(which we have set)). but its s setting back to null i.e response=null. so i am getting null pointer exception.
hope u get it.
i am really sorry i am nt able to provide stack trace.
can you suggest something on this.

[Tolls]

Sorry.
I find it hard to believe you cannot get a stack trace.
Without it how do you know where the exception is thrown?

[acmohan]

I have clearly mentioned where i am getting error.

expect(DaoImpl.getService().process(
request, null, null)).andReturn(response);

i am unable to find why i am getting such error.hope you get it.

[Tolls]

How did you know that was the line if you can't post a stack trace?
Because otherwise, DaoImpl is null, the return from getService() is null, or the expect() is returning null.
Now, according to your setup code DaoImpl and Service are set...

[acmohan]

when ever we call "getService().process(request, null, null))" we expect it to return response which we have defined.but i am getting it as null. i am not able get y. if you have any suggestion how can i trace it,it will be great help else will leave this thread here :(.

[Tolls]

So?
You say you have a NullPointerException.
You say it is on this line:

expect(DaoImpl.getService().process(
				request, null, null)).andReturn(response);

even though you apparently cannot give a stack trace (which begs the question of how you know it is on that line).

In which case you need to check whether DaoImpl, or the thing returned by getService(), is null.
Write some code before the expect() call to check that, and see.
Until you do that no one can help you.

[acmohan]

ok will try that out.thanks for ur time.
