EasyMock :: unexpected call call

[kakachis]

Hello,

I have a problem with easymock when i test a method the error is :

java.lang.AssertionError: 
  Unexpected method call openSession("user", "password"):
    openSession("user", "password"): expected: 1, actual: 1 (+1)

I don't understand why this exception is called . can some one help me

thank's

in your mock object you would have written an expectation for method openSession("user", "password")
i guess your code will be something like

expect(mockServiceObj.openSession("user", "password")).andReturn()...
or
mockServiceObj.openSession("user", "password");

Easy mock assumes that the above call willbe made only once throughout the testcase method. But your service layer tries to do this call more than once. Try to look into your implementation, find out the number of time the above method is being called and rewrite the expectation (Which might look something like below)


expect(mockServiceObj.openSession("user", "password")).andReturn().anyTimes()
or
expect(mockServiceObj.openSession("user", "password")).andReturn().times(n);

where n: number of times the method gets called.

mockServiceObj.openSession("user", "password");
expectLastCall().times(n);


Hope this helps.

Tank you parveen ,

really i have the expect method. the problem i had is that i have a bean wich call my client this client abstract the real web service. i solved the problem withe expectandstubreturn method.

Really i don't understand the principle but my problem is solved.

Thank you

I have a somehow different question, though. What is meant by mock objects expectation. sorry if this might sound dumb. i am a newbie in mock objects.

in my case actually, I have something like this in my testClass:

EM em = EasyMock.createMock(EM.class);
RD roleD = EasyMock.createMock(RD.class);
// add mock object expectations here

EasyMock.replay(em);
EasyMock.replay(roleD);

RD result = testClass.methodCalled(em, rD);

// add additional test code here
EasyMock.verify(em);
EasyMock.verify(roleDetails);

assertNotNull(result);

so the error said:
java.lang.AssertionError
Unexpected method <unexpectedMethodCalled>
where <unexpectedMethodCalled> is actually called in the <methodCalled> in the real code

what could be the possible cause for this? how do i solve it?

thanks so much.
