EasyMock dummy question

[nlhma nlhmaLastName]

Hi,

I wrote the following small piece of code to get familiar with EasyMock and somehow the unit test always failed (AssertionFailedError: expected:<0> but was: <99>):

public class EasyMockTest {
    private IMocksControl mockCtrl = EasyMock.createControl();
    private InputStream mockInput;
    
    @Before
    public void setUp() {
        mockInput = EasyMock.createMock(InputStream.class);
    }
    
    @Test
    public void dummyEasyMockTest() 
        throws IOException {
        char inputChar = 'c';
        int inputInt = (int)inputChar;
        EasyMock.expect(mockInput.read()).andReturn(inputInt);        
        mockCtrl.replay();
        int outputInt = mockInput.read();
        mockCtrl.verify();
        
        Assert.assertEquals(inputInt, outputInt);
    }
}

I am using EasyMock 3.0, cglib 2.2, objenesis 1.2, asm 3.3, and junit 4.0. Could you guys please help let me know what went wrong with the code?

Thank you very much.

That's because you are creating your mock using the static EasyMock.createMock method and then replaying and verifying the mock control.

To simplify your code and make it work you can do the following:

public class EasyMockTest extends EasyMockSupport {

    private InputStream mockInput;

    @Before
    public void setUp() {
        mockInput = createMock(InputStream.class);
    }

    @Test
    public void dummyEasyMockTest() throws IOException {
        char inputChar = 'c';
        int inputInt = (int) inputChar;
        expect(mockInput.read()).andReturn(inputInt);
        replayAll();
        int outputInt = mockInput.read();
        verifyAll();

        assertEquals(inputInt, outputInt);
    }
}

Oh so it is the way EasyMock 3 works? I did it like in my code because I saw some examples from EasyMock 2.
