使用TestNG集成测试Spring Boot web应用程序

我们最近将我们的应用程序与Spring引导集成在一起。我们的测试案例基于testng框架。我们的基础测试类看起来如下使用TestNG集成测试Spring Boot web应用程序

@SpringApplicationConfiguration(classes = Application.class) 
    @ActiveProfiles(profiles = "test") 
    @WebAppConfiguration 
    @IntegrationTest 
    public class BaseTestCase extends AbstractTestNGSpringContextTests { 
    }

我们定义上面的类来建立有效简并加载应用程序上下文。所有集成测试类扩展BaseTestCase

我们的一个基本的测试案例看起来像下面

@Test 
    public void testPing() throws Exception{ 
     RestTemplate restTemplate = new RestTemplate(); 
     String response = restTemplate.getForObject(
       <some url>, 
       String.class); 
     Assert.assertNotNull(response); 
    }

当我们运行上面的测试情况下，我们得到了以下异常

FAILED CONFIGURATION: @BeforeClass springTestContextPrepareTestInstance 
java.lang.IllegalStateException: The WebApplicationContext for test context [[email protected] testClass = DataResourceTest, testInstance = [email protected], testMethod = [null], testException = [null], mergedContextConfiguration = [[email protected] testClass = DataResourceTest, locations = '{}', classes = '{class com.xactly.insights.app.Application}', contextInitializerClasses = '[]', activeProfiles = '{test}', resourceBasePath = 'src/main/webapp', contextLoader = 'org.springframework.boot.test.SpringApplicationContextLoader', parent = [null]]] must be configured with a MockServletContext.

我们用春天启动版本1.1.5.RELEASE和testng版本6.1.1。有人可以解释如何解决上述问题吗？

这个类，你可以张贴一些代码，也许说明你已经尝试过什么，什么是行不通的。 – 2014-08-28 09:48:20

的问题是，默认情况下，AbstractTestNGSpringContextTests使ServletTestExecutionListener。这位听众提供模拟 Servlet API支持您的测试。在这种情况下，这并不合适，因为您正在运行Spring Boot集成测试，其中启动了嵌入式Tomcat服务器，为您提供真正的ServletContext。这会导致您看到的失败，因为ServletTestExecutionListener声称ServletContext是MockServletContext实例。

可以通过禁用AbstractTestNGSpringContextTests的测试执行听众的继承和明确使用@TestExecutionListeners配置，而不是他们解决这个问题：

@SpringApplicationConfiguration(classes = Application.class) 
@WebAppConfiguration 
@IntegrationTest 
@TestExecutionListeners(inheritListeners = false, listeners = { 
     DependencyInjectionTestExecutionListener.class, 
     DirtiesContextTestExecutionListener.class }) 
public class BaseTestCase extends AbstractTestNGSpringContextTests { 

}

非常感谢。这工作像魔术一样 – 2014-08-28 17:40:35

我有同样的问题。令人惊讶的是什么工作对我来说是创造SpringContextLoadingTest类，把所有的注释出现，而是延长AbstractTestNGSpringContextTests
