java – 无法实例化TestExecutionListener

当我从 Eclipse中运行下面的硒测试时,我得到一系列不能在我的日志中实例化TestExecutionListener消息.

这是实际的测试.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
public final class TestWebpage {
   private static final Logger LOG = Logger.getLogger(TestWebpage.class);

   @Autowired
   private WebDriver driver;

   @Test
   public void testLoadingPage() {
      LOG.debug("Hello World!");
   }
}

这是日志

0    [main] INFO  org.springframework.test.context.support.DefaultTestContextBootstrapper  - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener,org.springframework.test.context.support.DependencyInjectionTestExecutionListener,org.springframework.test.context.support.DirtiesContextTestExecutionListener,org.springframework.test.context.transaction.TransactionalTestExecutionListener,org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener]

注意我使用的是Spring 4.1.0.RELEASE.

一个解决方案,三个额外的依赖

我在answer to a previous question中注意到了添加@WebAppConfiguration的建议

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
@WebAppConfiguration
public final class TestWebpage {

那我在我的pom.xml中需要三个额外的依赖来支持：

javax.servlet-api
spring-jdbc
spring-web

为什么我根本不使用JDBC,或者使用spring-web / servlet的任何东西,都需要这些额外的东西 – 这只是我自己配置的一个硒测试.

有更简单的方法吗？我错过了更大的东西吗？

配置类

这是我配置我的测试的类.

public final class SeleniumConfig {

   @Bean
   public String baseUrl() {
      return "http://localhost:8888/";
   }

   @Bean
   public WebDriver driver() {
      return new CloseableFirefoxDriver();
   }

   class CloseableFirefoxDriver extends FirefoxDriver implements DisposableBean {
      public void destroy() throws Exception {
         quit();
      }
   }
}

POM

我的pom.xml(在我添加额外的依赖项之前).

解决方法

javax.servlet-api
spring-jdbc
spring-web

我可以把我的测试类定义为：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SeleniumConfig.class)
public final class TestWebpage {

我会得到这个日志记录：

0    [main] INFO  org.springframework.test.context.support.DefaultTestContextBootstrapper  - Loaded default TestExecutionListener class names from location [META-INF/spring.factories]: [org.springframework.test.context.web.ServletTestExecutionListener,org.springframework.test.context.jdbc.SqlScriptsTestExecutionListener]

没有错误,但显然,春天在后台正在做一些相当的工作.
