问题描述
对于我的Spring-Boot应用程序,我通过@Configuration文件提供了RestTemplate,因此我可以添加合理的默认值(ex Timeouts)。对于我的集成测试,我想模拟RestTemplate,因为我不想连接到外部服务 - 我知道期望的响应。我尝试在集成测试包中提供不同的实现,希望后者将覆盖实际的实现,但是反过来检查日志:真正的实现覆盖了测试的实现。
如何确保TestConfig中的那个是使用过的?
For my Spring-Boot app I provide a RestTemplate though a @Configuration file so I can add sensible defaults(ex Timeouts). For my integration tests I would like to mock the RestTemplate as I dont want to connect to external services - I know what responses to expect. I tried providing a different implementation in the integration-test package in the hope that the latter will override the real implementation , but checking the logs it`s the other way around : the real implementation overrides the test one.
How can I make sure the one from the TestConfig is the one used?
这是我的配置文件:
@Configuration
public class RestTemplateProvider {
private static final int DEFAULT_SERVICE_TIMEOUT = 5_000;
@Bean
public RestTemplate restTemplate(){
return new RestTemplate(buildClientConfigurationFactory());
}
private ClientHttpRequestFactory buildClientConfigurationFactory() {
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setReadTimeout(DEFAULT_SERVICE_TIMEOUT);
factory.setConnectTimeout(DEFAULT_SERVICE_TIMEOUT);
return factory;
}
}
整合测试:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = TestConfiguration.class)
@WebAppConfiguration
@ActiveProfiles("it")
public abstract class IntegrationTest {}
TestConfiguration类:
TestConfiguration class:
@Configuration
@Import({Application.class, MockRestTemplateConfiguration.class})
public class TestConfiguration {}
最后MockRestTemplateConfiguration
And finally MockRestTemplateConfiguration
@Configuration
public class MockRestTemplateConfiguration {
@Bean
public RestTemplate restTemplate() {
return Mockito.mock(RestTemplate.class)
}
}
推荐答案
自Spring Boot 1.4以来。 x有一个选项可以使用 @MockBean
注释来伪造Spring bean。
Since Spring Boot 1.4.x there is an option to use @MockBean
annotation to fake Spring beans.
评论反应:
要保留缓存中的上下文,请不要使用 @DirtiesContext
,但是使用 @ContextConfiguration(name =contextWithFakeBean)
并且它将创建单独的上下文,同时它将保留默认上下文在缓存中。 Spring会在缓存中保留两个(或者你有多少个上下文)。
To keep context in cache do not use @DirtiesContext
, but use @ContextConfiguration(name = "contextWithFakeBean")
and it will create separate context, while it will keep default context in cache. Spring will keep both (or how many contexts you have) in cache.
我们的构建方式是这样的,大多数测试都使用默认的非流量配置,但我们有4-5个伪造的测试。默认上下文很好地重用
Our build is this way, where most of the tests are using default non-poluted config, but we have 4-5 tests that are faking beans. Default context is nicely reused
