Hibernate开发及整合应用大全 蔡雪焘编著 本书用典型的示例剖析Hibernate开发中的重点和难点

package login;



import javax.servlet.http.HttpServletRequest;
import org.jmock.Mock;
import org.jmock.MockObjectTestCase;
public class LoginServletMockTest extends MockObjectTestCase {

    public void testMockRequest1() {
        //构造一个Mock对象，参数必须是接口
        Mock mock = new Mock(HttpServletRequest.class);
        mock.expects(atLeastOnce())			//表示此方法至少执行一次
			.method("getParameter")			//方法名为getParameter
			.with(eq("username"))			//方法参数为"username"
			.will(returnValue("tomclus"));	//方法返回值是"tomclus"
        mock.expects(atLeastOnce())
			.method("getParameter")
			.with(eq("password"))
			.will(returnValue("abcd"));
        //根据Mock对象获取一个HttpServletRequest对象的替身
        HttpServletRequest request = (HttpServletRequest) mock.proxy();
        //断言调用结果
        assertEquals(true,new LoginServlet().isValidUser(request));
    }
    public static void main(String[] args) {
