使用黄瓜时,Spring Boot在嵌入式Cassandra之前加载,我该如何解决?

我在使用spring-cassandra-unit,spring-boot和spring-cucumber时遇到一些问题。下面的配置对于单元测试很好用,但是一旦我将spring-cucumber添加到混合中并尝试进行一些集成测试,它似乎完全忽略了MyCustomOrderedTestExecutionListener并在cassandra之前加载spring boot,给我一个“ NoHostFoundException”。

我真的可以使用有关如何确保首先加载嵌入式cassandra的建议。任何帮助将不胜感激。

以下设置:

@ActiveProfile("INTEGRATION_TEST")
@SpringBootTest
@EmbeddedCassandra(configuration = "cassandra.yaml")
@TestExecutionListeners(
  listeners = MyCustomOrderedTestExecutionListener.class,
  mergeMode = MERGE_WITH_DEFAULTS)
@CassandraDataSet(value = "cql/dataset1.cql", keyspace = "mykeyspace")
public class TestStepDef{

//omitted for brevity

} 

我的自定义订购的测试执行侦听器:

public class MyCustomOrderedTestExecutionListener extends AbstractTestExecutionListener {

    @Override
    public void afterTestMethod(TestContext testContext) throws Exception {
       //omitted for brevity
    }

    @Override
    public int getOrder() {
        return  Ordered.HIGHEST_PRECEDENCE;
    }
}

黄瓜测试运行器:

@RunWith(Cucumber.class)
@CucumberOptions(features="resources/features", glue="resources/glue")
public class TestRunner {}

编辑:

看一下黄瓜弹簧的弹簧工厂,甚至在执行beforeTestClass之前就已经加载了应用上下文(beforeTestClass由notifyContextManagerAboutTestClassStarted执行):

 public void start() {
        if (this.stepClassWithSpringContext != null) {
            this.testContextManager = new CucumberTestContextManager(this.stepClassWithSpringContext);  
        } else if (this.beanFactory == null) {
            this.beanFactory = this.createFallbackContext();
        }

        this.notifyContextManagerAboutTestClassStarted();
        if (this.beanFactory == null || this.isNewContextCreated()) {
            this.beanFactory = this.testContextManager.getBeanFactory();
            Iterator var1 = this.stepClasses.iterator();

            while(var1.hasNext()) {
                Class<?> stepClass = (Class)var1.next();
                this.registerStepClassBeanDefinition(this.beanFactory, stepClass);
            }
        }

        GlueCodeContext.INSTANCE.start();
    }

深入了解,我们可以看到此处已加载应用上下文:

class CucumberTestContextManager extends TestContextManager {
    public CucumberTestContextManager(Class<?> testClass) {
        super(testClass);
        this.registerGlueCodeScope(this.getContext());
    }

     private ConfigurableApplicationContext getContext() {
    return (ConfigurableApplicationContext)this.getTestContext().getApplicationContext();
     }
...

}

关于如何解决此问题的任何建议?

当前,黄瓜仅调用TestContextManager.beforeClassTestContextManager.afterClass。但是,这是在每种情况之前发生的,因此覆盖TestExecutionListener.afterTestClass应该可以解决问题。

这是我的方法:

IntegrationConfig:

class IntegrationConfiguration {
// your cassandra startup
}

ComponentTestSpecification

@ContextConfiguration(classes = Application.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
@Import(IntegrationConfiguration.class)
abstract class ComponentTestSpecification {
// reusable integration-test methods here
}

测试(常规,应该可以转换为jUnit /其他):

class AccessControllerSpec extends ComponentTestSpecification {
// test methods
}

您可以通过https://github.com/nosan/embedded-cassandra项目

执行此操作
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;

import com.github.nosan.embedded.cassandra.test.spring.EmbeddedCassandra;

@SpringBootTest
@ActiveProfiles("INTEGRATION_TEST")
@EmbeddedCassandra(configurationFile = "cassandra.yaml", scripts = "cql/dataset1.cql")
public class TestStepDef {


}

@EmbeddedCassandraorg.springframework.test.context.ContextCustomizer处理,因此启动不会有任何问题。
