无法在4.1.4中使用Fongo进行单元测试失败-在3.1.4中工作

Question

https://github.com/sanjuthomas/spring-data-mongodb

为了理解如何使用fongo对mongo应用程序进行单元测试，我尝试了几个例子，比如上面的例子。所有的例子都能用--包括上面的例子，但是当我把pom升级到spring boot支持的最新版本时，所有的例子都失败了。似乎不再为测试加载应用程序上下文。这个单元测试功能被破坏了吗?或者我需要修改代码吗？

下面是在Spring 3中运行失败的代码-现在规则失败，声明上下文中不存在mongo实例：

Answer 1

对于mongo()，您必须使用Annotation @Bean

@Bean 
@Override
public Mongo mongo() {
            return new Fongo("trade-test").getMongo();
}
