测试类的Powermock抛出类未找到异常答案

【问题标题】：Powermock throwing Class Not Found Exception for Test class测试类的Powermock抛出类未找到异常

【问题描述】：

我正在使用带有 Ant 构建和 Spring 3.0 的 PowerMock。当我使用 SpringJunit4ClassRunner 注释时，测试运行良好。但是当我用PowerMockRunnerDelegate 实现PowermockRunner (1.6.5) 时，跑步者无法检测到测试类本身。

@Named("teskListTest")
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:conf/TestBeans.xml"})
@PrepareForTest(SysList.class)
public class SysListTest {  

SysList sysList;

@Test
public void addSysWithIdTest() throws Exception {

    System.out.println("SysListTest : Entering addSysWithIdTest ");

    java.util.logging.Logger log = Mockito.mock(java.util.logging.Logger.class);
    sysList = new SysList(log);
    Component comp = Mockito.mock(Component.class);
    PowerMockito.whenNew(Component.class).withNoArguments().thenReturn(comp);
    sysList.test();
    Mockito.verify(comp).getId();

    System.out.println("sysListTest : Exiting addsysWithIdTest");
}

我得到的例外是：

我尝试使用 Mockito 1.9.5、1.10.16。尝试使用版本为 1.6.1 和 1.6.5 以及 Junit 4.12、4.11 的 PowerMock jar。异常从未改变。

【解决方案1】：

您的生产类似乎不是测试类路径的一部分。我认为问题在于您的build.xml。请查看 JUnit 的 "Getting started – Ant" 文章。
