[英]Mocking a configuration property when testing a Spring bean
I have a Spring bean that reads a configuration property value from application.yml
我有一个 Spring bean,它从
application.yml
读取配置属性值
public class AutoDisableRolesService {
@Value("${cron.enabled}")
private boolean runTask;
// remainder of class omitted
}
In the application.yml this property is set to false在 application.yml 中,此属性设置为 false
cron:
enabled: false
But when I run the test, I want it to be true.但是当我运行测试时,我希望它是真的。 I've tried the following, but it does not seem to work
我尝试了以下方法,但似乎不起作用
@SpringBootTest(properties = { "cron.enabled=true" })
@ExtendWith(MockitoExtension.class)
public class AutoDisableRolesServiceTests {
@Mock
private UserRoleRepository userRoleRepository;
@InjectMocks
private AutoDisableRolesService autoDisableRolesService;
// remainder of test class omitted
}
I've also tried the following, without success我也尝试了以下方法,但没有成功
@ContextConfiguration(classes = AutoDisableRolesService.class)
@TestPropertySource(properties = "cron.enabled=true")
@ExtendWith(MockitoExtension.class)
public class AutoDisableRolesServiceTests {
@Mock
private UserRoleRepository userRoleRepository;
@InjectMocks
private AutoDisableRolesService autoDisableRolesService;
// remainder of test class omitted
}
You're mixing up two types of test set ups;您正在混合两种类型的测试设置; A Spring boot test setup with a Mockito test set up.
带有 Mockito 测试设置的 Spring 启动测试设置。 By using
@InjectMocks
on your class under test, Mockito instantiates the class and injects all the fields annotated with @Mock
, bypassing the Spring TestApplicationContext setup.通过在被测类上使用
@InjectMocks
,Mockito 实例化该类并注入所有用@Mock
注释的字段,绕过 Spring TestApplicationContext 设置。
Either use a Spring test set up using:使用以下方法设置 Spring 测试:
@SpringBootTest(properties = { "cron.enabled=true" })
public class AutoDisableRolesServiceTests {
@MockBean
private UserRoleRepository userRoleRepository;
@Autowired
private AutoDisableRolesService autoDisableRolesService;
// remainder of test class omitted
}
Or a mockito set up using:或使用以下方法设置的 mockito:
public class AutoDisableRolesServiceTests {
@Mock
private UserRoleRepository userRoleRepository;
@InjectMocks
private AutoDisableRolesService autoDisableRolesService;
@BeforeEach
public void setUp() {
ReflectionTestUtils.setField(autoDisableRolesService, "runTask", true);
}
}

If you don't need a full @SpringBootTest set up, use如果您不需要完整的 @SpringBootTest 设置,请使用
@ExtendWith(SpringExtension.class)
@TestPropertySource(properties={"cron.enabled=true"})
@ContextConfiguration(classes = { AutoDisableRolesService.class})
public class AutoDisableRolesServiceTests {
@MockBean
private UserRoleRepository userRoleRepository;
@Autowired
private AutoDisableRolesService autoDisableRolesService;
// remainder of test class omitted
}
The difference between @SpringBootTest and @ExtendsWith(SpringExtension.class) is that a @SpringBootTest loads the full (test)ApplicationContext while the latter only loads a partial context, which is faster but doesn't include everything. @SpringBootTest 和@ExtendsWith(SpringExtension.class) 之间的区别在于@SpringBootTest 加载完整的(测试)ApplicationContext,而后者只加载部分上下文,这更快但不包括所有内容。
