测试类：

package edu.com;import static org.junit.Assert.*;import mockit.Deencapsulation;import org.junit.After;import org.junit.Before;import org.junit.Test;public class TTest {    @Before    public void setUp() throws Exception {    }    @After    public void tearDown() throws Exception {    }    @Test    public void testPrivateMethod() {        // 新建一个对象，如果直接用T.class来invoke会报错        /**         * int actual = Deencapsulation.invoke(T.class, "privateMethod", 3, 5);         * java.lang.IllegalArgumentException: Attempted to invoke non-static method without an instance to invoke it on         */        T t = new T();        int expected = 8;        int actual = Deencapsulation.invoke(t, "privateMethod", 3, 5);        assertEquals(expected, actual);    }}
