使用junit / spring-test运行测试用例来测试spring WS webservice时出现NoInitialContextFound异常

我有一个使用Spring WS开发的Soap Web服务。我想创建一个Junit测试用例，在它转移到其他环境之前测试服务（从开发到坐到uat到prod）。

我正在尝试像这样使用Spring测试MockWebServiceClient 

@RunWith(SpringJUnit4ClassRunner.class)                                                  
@ContextConfiguration(locations = { "classpath:WEB-INF/spring-ws-servlet.xml" })                                           
public class AccountSearchEndpointTests {

@Autowired
private ApplicationContext applicationContext;

private MockWebServiceClient mockClient;

@Before
public void createClient() {
mockClient = MockWebServiceClient.createClient(applicationContext);
}

@Test
public void testWsEndPointTest() throws Exception {
    StringSource requestPayload = new StringSource(
      ""); //omitted actual request
    StringSource responsePayload = new StringSource(""); //omitted actual response
        mockClient.sendRequest(withPayload(requestPayload)).andExpect(payload(responsePayload));
}

然而，我得到的错误是

这是spring-ws-servlet中的bean 

<bean id="bean" init-method="initialize" destroy-method="terminate"
    class="com.bean" />

并且在bean的初始化中发生这种情况

ctx = new InitialContext();
       ds = (DataSource) ctx.lookup(DS_NAME);

据我所知，webservice应该在像tomcat这样的容器中运行，但后来我想知道如何在Spring测试中模拟它/配置它。基本上我想知道如何使用junit来测试web服务！

这基本上是https://stackoverflow.com/a/5947016/388980的副本。

请查看那里讨论的解决方案。

总之，您应该不直接在代码中执行JDNI查找。相反，您应该在Spring配置中外部化JDNI查找，然后只将Spring注入DataSource组件。

然后您可以使用嵌入式数据库（例如，H2，HSQL，Derby - Spring支持所有这三个），同时测试并将嵌入式数据库的DataSource注入您的组件。

作为替代方案，您可以将数据访问代码移动到专用的存储库或DAO实现，并将模拟注入到Web服务端点中 - 例如，使用Mockito。

如果您不熟悉Spring中的 bean定义概要文件，则应阅读Spring参考手册的相应部分。 测试一章演示了如何在测试中使用配置文件prod和dev。
