如今，我们的很多应用程序是基于Spring的，通过Spring IOC容器来管理我们的Java对象。所以这里单独提出对Spring Bean如何Mock方法。
以上述提到如何Mock类中的提到的AnOrdinaryClass为例，先把这个类配置在Spring的配置文件中

同样地，讲述2种Mock方法
-
用Expectations来Mock。

//用Expectations来Mock Spring Bean
@ContextConfiguration(locations = { "/META-INF/applicationContext1.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class SpringBeanMockingByExpectationsTest {
// 注入Spring Bean，Mock这个实例，就达到了Mock Spring Bean的目的
@Resource
AnOrdinaryClass anOrdinaryBean;
@Test
public void testSpringBeanMockingByExpectation() {
// 直接把实例传给Expectations的构造函数即可Mock这个实例
new Expectations(anOrdinaryBean) {
{
// 尽管这里也可以Mock静态方法，但不推荐在这里写。静态方法的Mock应该是针对类的
// mock普通方法
anOrdinaryBean.ordinaryMethod();
result = 20;
// mock final方法
anOrdinaryBean.finalMethod();
result = 30;
// native, private方法无法用Expectations来Mock
}
};
Assert.assertTrue(AnOrdinaryClass.staticMethod() == 1);
Assert.assertTrue(anOrdinaryBean.ordinaryMethod() == 20);
Assert.assertTrue(anOrdinaryBean.finalMethod() == 30);
// 用Expectations无法mock native方法
Assert.assertTrue(anOrdinaryBean.navtiveMethod() == 4);
// 用Expectations无法mock private方法
Assert.assertTrue(anOrdinaryBean.callPrivateMethod() == 5);
}
@BeforeClass
// 加载AnOrdinaryClass类的native方法的native实现
public static void loadNative() throws Throwable {
JNITools.loadNative();
}
}

用MockUp来Mock

//用MockUp来Mock Spring Bean
@ContextConfiguration(locations = { "/META-INF/applicationContext1.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class SpringBeanMockingByMockUpTest {
// 注入Spring Bean，Mock这个实例，就达到了Mock Spring Bean的目的
@Resource
AnOrdinaryClass anOrdinaryBean;
@Test
public void testSpringBeanMockingByMockUp() {
// 静态方法被mock了
Assert.assertTrue(AnOrdinaryClass.staticMethod() == 10);
// 普通方法被mock了
Assert.assertTrue(anOrdinaryBean.ordinaryMethod() == 20);
// final方法被mock了
Assert.assertTrue(anOrdinaryBean.finalMethod() == 30);
// native方法被mock了
Assert.assertTrue(anOrdinaryBean.navtiveMethod() == 40);
// private方法被mock了
Assert.assertTrue(anOrdinaryBean.callPrivateMethod() == 50);
}
@BeforeClass
public static void beforeClassMethods() throws Throwable {
loadNative();
// 必须在Spring容器初始化前，就对Spring Bean的类做MockUp
addMockUps();
}
// 加载AnOrdinaryClass类的native方法的native实现
public static void loadNative() throws Throwable {
JNITools.loadNative();
}
// 对AnOrdinaryClass的Class
public static class AnOrdinaryClassMockUp extends MockUp<AnOrdinaryClass> {
// Mock静态方法
@Mock
public static int staticMethod() {
return 10;
}
// Mock普通方法
@Mock
public int ordinaryMethod() {
return 20;
}
@Mock
// Mock final方法
public final int finalMethod() {
return 30;
}
// Mock native方法
@Mock
public int navtiveMethod() {
return 40;
}
// Mock private方法
@Mock
private int privateMethod() {
return 50;
}
}
// 添加MockUp
public static void addMockUps() {
new AnOrdinaryClassMockUp();
}
}
