在 Spring 应用程序中使用 Spock 进行 Autowire 模拟

Question

我想用 Spock 测试我的 Java 应用程序。我有一个类AmiPlugin.java，它通过构造函数注入有两个依赖项：

@Autowired
AmiPlugin(final EC2InstanceContextProvider contextProvider,
                         final ViolationSink violationSink) {
     super(contextProvider);
     this.violationSink = violationSink;
}

我的 groovy 测试如下所示：

@ContextConfiguration(loader = SpringApplicationContextLoader   , classes = [AmiPlugin.class])
class AmiPluginSpec extends Specification{

@Autowired
AmiPlugin amiPlugin;

def "Test if plugin supports the right Cloudtrail events"(String event, Boolean supports){
    expect:
    amiPlugin.supportsEventName().test(event) == supports

    where:
    event                   | supports
    "RunInstances"          | true
    "StartInstances"        | false
    "TerminateInstances"    | false
    "StopInstances"         | false
    "Foobar"                | false
}

但是，运行它会给我一个NoSuchBeanDefinitionException。在 jUnit 中，我会在同一个文件中使用带有 @configuration 的静态类，它返回所需的模拟，但这不起作用。 使用

    @Bean
    EC2InstanceContextProvider ec2InstanceContextProviderMock(){
        EC2InstanceContextProvider provider = Mock()
        return provider
    }

也不行。

如何在 Spock 中自动装配模拟？

编辑没问题

Answer 1

您正在寻找的是分离的模拟，可让您创建不符合规范的模拟。 https://github.com/spockframework/spock/issues/86 - 能够将 Spock 模拟作为 Spring bean 注入。在那里你可以找到一个 hack 如何做到这一点。

2017-03-25 更新：Spock 在 1.1 版中添加了对分离模拟的完全支持。用法示例可以在in the documentation 和this SO answer 中找到。

Answer 2

您可以在 Spock 1.2 中使用 SpringBean 注解：https://objectpartners.com/2018/06/14/spock-1-2-annotations-for-spring-integration-testing/

所以你的代码会变成：

@ContextConfiguration(loader = SpringApplicationContextLoader   , classes = [AmiPlugin.class])
class AmiPluginSpec extends Specification{

@SpringBean
AmiPlugin amiPlugin = Mock() 

def "Test if plugin supports the right Cloudtrail events"(String event, Boolean supports){
    expect:
    amiPlugin.supportsEventName().test(event) == supports

    where:
    event                   | supports
    "RunInstances"          | true
    "StartInstances"        | false
    "TerminateInstances"    | false
    "StopInstances"         | false
    "Foobar"                | false
}

您不再需要额外的配置类，因为 Spock 直接将 mock 注入到 spring 上下文中
