我们最近将我们的应用程序与 spring boot集成我们的测试用例基于testng框架. 我们的基础测试类如下所示 @SpringApplicationConfiguration(classes = Application.class) @ActiveProfiles(profiles = "test") @WebAppCo
我们的基础测试类如下所示
@SpringApplicationConfiguration(classes = Application.class)
@ActiveProfiles(profiles = "test")
@WebAppConfiguration
@IntegrationTest
public class BaseTestCase extends AbstractTestNGSpringContextTests {
}
我们定义了上面的类来设置活动配置文件并加载应用程序上下文.所有集成测试类都扩展了BaseTestCase
我们的一个基本测试用例如下所示
@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用例时,我们得到以下异常
FAILED CONFIGURATION: @BeforeClass springTestContextPrepareTestInstance
java.lang.IllegalStateException: The WebApplicationContext for test context [DefaultTestContext@11b72c96 testClass = DataResourceTest, testInstance = com.xactly.insights.resource.imp.DataResourceTest@5b630a31, testMethod = [null], testException = [null], mergedContextConfiguration = [WebMergedContextConfiguration@10d034f0 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.

我们使用spring boot版本1.1.5.RELEASE和testng版本6.1.1.有人可以说明如何解决上述问题吗？
问题是,默认情况下,AbstractTestNGSpringContextTests启用ServletTestExecutionListener.此侦听器为您的测试提供模拟Servlet API支持.在这种情况下,这是不合适的,因为您正在运行Spring Boot集成测试,其中为您启动了嵌入式Tomcat服务器,为您提供了真正的ServletContext.这导致您看到ServletTestExecutionListener声明ServletContext是MockServletContext实例时失败.您可以通过禁用AbstractTestNGSpringContextTests的测试执行侦听器的继承并使用@TestExecutionListeners显式配置它们来解决此问题：
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@IntegrationTest
@TestExecutionListeners(inheritListeners = false, listeners = {
DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class })
public class BaseTestCase extends AbstractTestNGSpringContextTests {
}
