我正在尝试使用Spock存根在服务类中模拟数据库/存储库的依赖关系,但是存根返回意外值时遇到问题。我不明白为什么只有在不将参数传递给模拟方法时存根才起作用。
given: 'I have client data'
Client client = new Client("Foo", "[email protected]")
and: 'a client repository always returns the id'
clientRepository = Stub(ClientRepository)
ClientEntity ce = new ClientEntity("Foo", "[email protected]")
clientRepository.create(ce) >> 1
when: 'I add the client'
ClientService clientService = new ClientServiceImpl(clientRepository)
Client addedClient = clientService.addClient(client)
then: 'The client object should be populated correctly'
addedClient.getId() == 1 // This fails b/c it's returning the id as 0
但是当我使用_参数测试通过时:
given: 'I have client data'
Client client = new Client("Foo", "[email protected]")
and: 'a client repository always returns the id'
clientRepository = Stub(ClientRepository)
clientRepository.create(_) >> 1
when: 'I add the client'
ClientService clientService = new ClientServiceImpl(clientRepository)
Client addedClient = clientService.addClient(client)
then: 'The client object should be populated correctly'
addedClient.getId() == 1 // This passes b/c it's returning the id as 1
这是服务类
@Service
public class ClientServiceImpl implements ClientService{
private ClientRepository clientRepository;
@Autowired
ClientServiceImpl(ClientRepository clientRepository){
this.clientRepository = clientRepository;
}
@Override
public Client addClient(Client client){
ClientEntity clientEntity = new ClientEntity(
client.getName(),
client.getEmailAddress()
);
int id = clientRepository.create(clientEntity);
client.setId(id);
return client;
}
}
和Spock的依赖
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-core</artifactId>
<version>1.3-groovy-2.5</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-spring</artifactId>
<version>1.3-groovy-2.5</version>
<scope>test</scope>
</dependency>
谢谢您的帮助!
如果你这样做
ClientEntity ce = new ClientEntity("Foo", "[email protected]")
clientRepository.create(ce) >> 1
并且未执行存根交互,则因为方法参数未根据您的期望进行匹配。我的猜测是,equals(..)
方法ClientEntity
不能按您期望的那样工作,并且给定的参数create(..)
不完全ce
是它的副本,而不能满足要求equals(..)
。
解决方案:修正您的equals(..)
方法。
