可以在类之间缓存Spring的应用程序上下文吗?

此配置位于 build.gradle

test {
    useJUnit()
    setForkEvery(0)
    setMaxParallelForks(1)
}

我们能够在单个JVM中运行所有测试。虽然我认为这是默认行为。

Spring Test Context Caching 在我的应用测试中使用这个属性。yml:

logging:
  level:
    org:
      springframework:
        test:
          context:
            cache: DEBUG

我注意到在同一个类中运行的测试方法的以下日志

2017-09-05 08:33:11.829 DEBUG 5764 --- [    Test worker] c.DefaultCacheAwareContextLoaderDelegate : Storing ApplicationContext in cache under key [THIS HAD SENSITIVE DATA]

还有更多的话要说 Retrieved ApplicationContext from cache with key... .

2017-09-05 08:33:12.971 DEBUG 10288 --- [    Test worker] c.DefaultCacheAwareContextLoaderDelegate : Storing ApplicationContext in cache under key [THIS HAD SENSITIVE DATA]

两个类的注释相同:

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles({"default", "profile-1", "profile-2"})
public class SomeControllerTest {

    // Test methods...
}

ApplicationContext

我都注意到了 应用程序上下文 对象大约同时存储在缓存中 08:33:11.829 和 08:33:12.971 . 测试运行程序是否在不同的线程中执行测试?
