Question

我有以下测试类：

@ActiveProfiles({ "DataTC", "test" })
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {BaseTestConfiguration.class, DataTestConfiguration.class, JpaConfiguration.class, PropertyPlaceholderConfiguration.class })
public class RegularDayToTimeSlotsTest {

    private static int NUMBER_OF_REGULAR_DAY_TO_TIME_SLOTS_IN_WEEK = 25;

    @Autowired
    private AdvertisementService advertisementService;

    @Test
    public void shouldNotContainSaturdayNorSunday() {
        Set<DayToTimeSlot> regularDayToTimeSlots = advertisementService.retrieveRegularDayToTimeSlots();
        assertThat(regularDayToTimeSlots).onProperty("day").excludes(Day.SATURDAY, Day.SUNDAY);
    }

    @Test
    public void shouldNotContainEveningNorNighttime() {
        Set<DayToTimeSlot> regularDayToTimeSlots = advertisementService.retrieveRegularDayToTimeSlots();
        assertThat(regularDayToTimeSlots).onProperty("timeSlot").excludes(TimeSlot.EVENING, TimeSlot.NIGHTTIME);
    }

    @Test
    public void shouldContainCorrectNumberOfDayToTimeSlots() {
        Set<DayToTimeSlot> regularDayToTimeSlots = advertisementService.retrieveRegularDayToTimeSlots();
        assertThat(regularDayToTimeSlots).hasSize(NUMBER_OF_REGULAR_DAY_TO_TIME_SLOTS_IN_WEEK);
    }
}

这是一个不需要任何ServletContext的集成测试。这是BaseTestConfiguration类：

@Configuration
@ComponentScan(basePackages = { "com.bignibou" }, excludeFilters = { @Filter(type = FilterType.CUSTOM, value = RooRegexFilter.class),
        @Filter(type = FilterType.ANNOTATION, value = Controller.class), @Filter(type = FilterType.ANNOTATION, value = ControllerAdvice.class),
        @Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class) })
public class BaseTestConfiguration {

}

这只是一个java配置类，旨在确保我的所有应用程序bean都被实例化并正确连接，但是没有考虑使用@EnableWebMvc注释的类，因为我不需要此集成测试的Servlet上下文。

不幸的是，无论我多少尝试排除Web / Mvc配置类，它都不起作用，并且还会选择使用@Configuration注释的@EnableWebMvc类。

我得到了这个例外：

有人可以帮忙吗？

事实上，有一种更简洁的方法来配置此类集成测试。

答案在于正确的关注点分离，不仅在类级别，而且在包级别。

始终建议实现和配置类都驻留在包层次结构中，以便正确分离关注点。特别是对于Web应用程序，强烈建议确保Web组件和Web配置位于专用的“Web”包中。例如，您可以考虑类似于以下的包层次结构：

com.example.domain
com.example.service
com.example.repository
com.example.web

使用这样的层次结构，您可以通过简化组件扫描配置，包括仅与当前应用程序或测试方案相关的那些基本软件包。通过这样做，通常不需要使用排除过滤器来处理您不想要的事情。相反，只需指定做想要的包。

顺便说一句，指定"com.bignibou"作为你的基础包实际上是一个最差的练习，因为它是无所不包的。

因此，请使用明确的包裹内容（而不是排除@Controller，@ControllerAdvice等），并查看这是否会让您的生活更轻松。 ;）

此致

我能够以非常污染的测试类的价格让它工作，但。这是：

@ActiveProfiles({ "DataTC", "test", "dev", "default" }) @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = { BaseTestConfiguration.class, DataTestConfiguration.class, JpaConfiguration.class, RestConfiguration.class, DevMailConfiguration.class, PropertyPlaceholderConfiguration.class, ThymeleafConfiguration.class }) public class RegularDayToTimeSlotsTest { ...

这是BaseTestConfiguration类：

@Configuration @ComponentScan(basePackages = { "com.bignibou" }, excludeFilters = { @Filter(type = FilterType.CUSTOM, value = RooRegexFilter.class), @Filter(type = FilterType.ANNOTATION, value = Controller.class), @Filter(type = FilterType.ANNOTATION, value = ControllerAdvice.class), @Filter(type = FilterType.ANNOTATION, value = Configuration.class) }) @ImportResource(value="classpath*:META-INF/spring/applicationContext-security.xml") public class BaseTestConfiguration { ...

必须有一种更简洁的方式来实施和运行集成测试......欢迎任何建议......
