java – Mockito在Spring中的间谍对象

当我尝试在单元测试中窥探对象时,
我有一个例外.
这是我的单元测试文件：

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath:spring/applicationContext.xml" })public class BookingSuperManTest {    BookInfoParams bookInfoParams;     HttpAttributeParams httpAttributeParams;    AbstractRequester requester;    public void beforeStartTest(){        bookInfoParams = Mockito.spy(new BookInfoParams());        httpAttributeParams = Mockito.spy(new HttpAttributeParams());    }    @Test    public void step1GoToHomePage() throws BookingException{        beforeStartTest();        requester = new Step1HomePage(bookInfoParams, httpAttributeParams);        requester.executeRequest();        Assert.assertNotNull(httpAttributeParams.getResponseGetRequest());    }}

我在链接分配bookInfoParams spy时得到了异常：

这是我的pom文件中的依赖项

<dependency>    <groupId>junit</groupId>    <artifactId>junit</artifactId>    <version>4.12</version></dependency><dependency>    <groupId>org.mockito</groupId>    <artifactId>mockito-core</artifactId>    <version>2.0.44-beta</version></dependency><dependency>    <groupId>org.powermock</groupId>    <artifactId>powermock-api-mockito</artifactId>    <version>1.6.4</version></dependency><dependency>    <groupId>org.powermock</groupId>    <artifactId>powermock-module-junit4</artifactId>    <version>1.6.4</version></dependency><dependency>    <groupId>cglib</groupId>    <artifactId>cglib</artifactId>    <version>3.2.1</version>    <scope>test</scope></dependency>

也许版本不兼容或我错过了什么？

解决方法:

它可能是依赖项的问题. powermock-api-mockito在mockito-core版本1.10.19上有编译时依赖性,但你也定义了对版本2.0.44-beta的依赖.这可能是类路径问题.尝试删除版本2.0.44-beta的显式依赖项.
