使用spock进行java单元测试时出现异常
我正在尝试使用spock测试基于java的web应用程序。之前我们使用Junit和Mockito进行测试 我正在尝试使用@Collaborator和@Subject来自动连接我的依赖项,就像我们在Mockito中使用@Mock和@injectmock一样 但它不起作用。我得到以下错误使用spock进行java单元测试时出现异常,java,unit-testing,spock,Java,Unit Testing,Spock,我正在尝试使用spock测试基于java的web应用程序。之前我们使用Junit和Mockito进行测试 我正在尝试使用@Collaborator和@Subject来自动连接我的依赖项,就像我们在Mockito中使用@Mock和@injectmock一样 但它不起作用。我得到以下错误 java.lang.NullPointerException at com.blogspot.toomuchcoding.spock.subjcollabs.NonConstructorBasedInjec

下面是我的测试代码
class UserServiceImplSpec extends Specification {
@Collaborator
UserDAO userDAO = Mock()
@Subject
UserService userService
def "should delete a user"(){
given: "given a user to delete"
User userToDelete = make(a(UserMaker.User));
when:
userService.deleteUser(userToDelete.getId());
then:
true
}
}
下面是我用于自动布线的扩展的URL
下面是我的依赖项
testCompile 'org.codehaus.groovy:groovy-all:2.4.5'
testCompile 'org.spockframework:spock-core:1.0-groovy-2.4'
testCompile 'org.spockframework:spock-spring:1.0-groovy-2.4'
testCompile "cglib:cglib:2.2"
testCompile 'org.objenesis:objenesis:2.2'
testCompile 'com.blogspot.toomuchcoding:spock-subjects-collaborators-extension:1.1.0'
下面是我的UserService和UserServiceImpl类
public interface UserService {
public void deleteUser(Long userId);
}
@Service("userService")
@Transactional(readOnly = true)
public class UserServiceImpl implements UserService {
@Autowired
private UserDAO userDAO;
@Autowired
private SecurityUtil securityUtil;
@Override
@Transactional(propagation = Propagation.REQUIRED, readOnly = false, rollbackForClassName = {"java.lang.Exception" })
public void deleteUser(Long userId) {
log.debug("Deleting an user entry with the user id: {}", userId);
User user = userDAO.findById(userId);
userDAO.delete(user);
}
}
您在@Collaborator、@Subject注入注释时遇到问题
import com.blogspot.toomuchcoding.spock.subjcollabs.Collaborator
import com.blogspot.toomuchcoding.spock.subjcollabs.Subject
添加依赖项:
<dependency>
<groupId>com.blogspot.toomuchcoding</groupId>
<artifactId>spock-subjects-collaborators-extension</artifactId>
<version>1.1.0</version>
<scope>test</scope>
</dependency>
问题在于@Subject注释类应该是一个实现,而不是一个接口
将
UserService
更改为userserviceinpl
就足够了。您是否使用大于或等于1.0.2的spock版本?如果没有,那么UserService
是否有公共构造函数?我正在使用的spock版本是org.spockframework:spock core:1.0-groovy-2.4hi!您是否也可以发布UserDAO和SecurityUtil代码?也许你可以发布一个示例项目并在这里提交一个问题,我们可以在gitter继续讨论-?哦,顺便说一句,如果你通过构造函数自动连线,你就不必做所有这些魔术:)如果有很多依赖项呢?我的项目中已经有了这些依赖项。此外,注释也被导入。如果问题出在导入语句上,代码将无法编译。
