本文提供了一个关于如何使用EasyMock进行单元测试的实例，详细介绍了如何通过mock objects来测试SampleServlet的isAuthenticated方法。文章包含了三个测试用例：验证已认证、未认证和无session的情况。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

public class SampleServlet extends HttpServlet {
    public boolean isAuthenticated(HttpServletRequest request){
        HttpSession session=request.getSession(false);
        if(session==null){
            return false;
        }
        String authenticationAttribute = (String) session.getAttribute("authenticated");
        return Boolean.valueOf(authenticationAttribute).booleanValue();
    }
}

本实例的测试目标是SampleServlet的isAuthenticated方法。为了测试该方法，可以有两种解决方案：

1.使用mock objects 来测试。

2.在容器中测试，即 in-container testing

首先使用第一种方法，使用mock objects来测试：

package easymock;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import static junit.framework.Assert.assertFalse;
import static junit.framework.Assert.assertTrue;
import static org.easymock.EasyMock.*;

public class EasyMockSampleServletTest {
    private SampleServlet sampleServlet;
    private HttpServletRequest mockHttpServletRequest;
    private HttpSession mockHttpSession;
    @Before
    public void setUp(){
        sampleServlet=new SampleServlet();
        mockHttpServletRequest=createStrictMock(HttpServletRequest.class);
        mockHttpSession = createStrictMock(HttpSession.class);
    }
    @Test
    public void testIsAuthenticatedAuthenticated() {
        expect(mockHttpServletRequest.getSession(eq(false))).andReturn(mockHttpSession);
        expect(mockHttpSession.getAttribute(eq("authenticated"))).andReturn("true");
        replay(mockHttpServletRequest);
        replay(mockHttpSession);
        assertTrue(sampleServlet.isAuthenticated(mockHttpServletRequest));
    }
    @Test
    public void testIsAuthenticatedNotAuthenticated() {
        expect(mockHttpSession.getAttribute(eq("authenticated"))).andReturn("false");
        replay(mockHttpSession);
        expect(mockHttpServletRequest.getSession(eq(false))).andReturn(mockHttpSession);
        replay(mockHttpServletRequest);
        assertFalse(sampleServlet.isAuthenticated(mockHttpServletRequest));
    }
    @Test
    public void testIsAuthenticatedNoSession() {
        expect(mockHttpServletRequest.getSession(eq(false))).andReturn(null);
        replay(mockHttpServletRequest);
        replay(mockHttpSession);
        assertFalse(sampleServlet.isAuthenticated(mockHttpServletRequest));
    }
    @After
    public void tearDown(){
        verify(mockHttpServletRequest);
        verify(mockHttpSession);
    }
}
