黄瓜+ spring:如何通过测试触发SmartLifecycle事件？

Question

我有一个黄瓜的弹簧引导应用程序。在调用bean的start-SmartLifecycle之前，我想在测试中执行某些事件。

Given Something that needs to happen before beans are started
And Beans start up now
Then Life is good

有办法做到这一点吗？默认情况下，Spring在执行任何Cucumber语句之前初始化并启动所有bean。

示例：

class Context {
  @Bean
  SomeBean someBean() { return new SomeBean(); }
}

class SomeBean implements SmartLifecycle {
  @Override
  void start() {
    // some meaningful work that depends on setup that needs to be done beforehand
  }
  // rest of interface implementation
}

黄瓜定义文件：

 @ContextConfiguration(classes = Context.class)
 class CucumberFeatures {
   @Autowired
   private SomeBean someBean;

   @Given("Something that needs to happen before beans are started")
   public void something() {
     // ...
   }

   @Given("Beans start up now")
   public void beansStarted() {
     // This should start beans in their defined order now
   }

   @Then("Life is good")
   public void lifeIsGood() { ... }
 }

在使用同一个容器将依赖项注入到测试中时，不能测试依赖项注入容器。注入依赖项要求已经刷新了应用程序上下文。

因此，您必须手动创建ApplicationContext的实例，并亲自管理它的生命周期。
