spring-boot - 斯波克测试 : Too few invocation

Question

我正在为一个服务类编写 Spock 测试，该服务类的方法在 spring boot 应用程序中调用 Dao 类中的另一个方法。但是，我得到:

 Too few invocations for:
 1 * dao.getAddressFromSomewhere("me")   (0 invocations)
 Unmatched invocations (ordered by similarity):
 None

下面是源代码和测试代码，有人可以告诉我我做错了什么吗？似乎 dao 模拟根本没有被调用并返回“USA”。我在网上做了一些研究，找不到我做错了什么。

@Service
public class ServiceClass 
{
    @Autowired
    private DaoClass dao;

    public String getAddress(String name) {         
        return dao.getAddressFromSomewhere(name);
    }
}

@Component
public class DaoClass {
     public String getAddressFromSomewhere(String name) {
     // get address from DB
     ......
     }
}

这是我的 Spock 测试代码:

@ContextConfiguration
@Import(ServiceClass.class)
public class Test extends Specification {

@Autowired
private DaoClass dao;
@Autowired
private ServiceClass service;

@TestConfiguration
static class MockConfig {
    def detachedMockFactory = new DetachedMockFactory()
    @Bean
    DaoClass dao() {
        return detachedMockFactory.Mock(DaoClass)
    }
}

def "Test Success Senario"() {                     
    given: "dao"
          dao.getAddressFromSomewhere("me") >> "USA";

    when: "call service "
       def actualResponse = service.getAddress("me");

    then: "dao should be invoked with given response"
       1 * dao.getAddressFromSomewhere("me")
       actualResponse == "USA"
 }
}

Answer 1

通过在 then: 中编写 1 * dao.getAddressFromSomewhere("me") block ，您只需覆盖交互 dao.getAddressFromSomewhere("me") >> "USA" 在你的 given: block 中。通过不通过 >>> 声明返回值，您只需告诉 mock 返回 null。您可以使用 Spock doc 检查交互顺序:

...Interactions declared in a then: block are matched against before any other interactions. This allows to override interactions declared in, say, a setup method with interactions declared in a then: block.

您可以通过多种方式重写您的示例:

1. 在 given: block 中声明您的交互

def "Test Success Senario"() {
    given: "dao"
    1 * dao.getAddressFromSomewhere("me") >> "USA"

    when: "call service "
    def actualResponse = service.getAddress("me")

    then: "dao should be invoked with given response"
    actualResponse == "USA"
}

1. 在 then: block 中声明您的交互:

def "Test Success Senario"() {
    when: "call service "
    def actualResponse = service.getAddress("me")

    then: "dao should be invoked with given response"
    1 * dao.getAddressFromSomewhere("me") >> "USA"
    actualResponse == "USA"
}
