Missing dependencies hasSize() and hasProperty() when implementing unit test of Spring controller
提问by Mr Morgan
I am trying to implement a unit test of a method in a Spring MVC controller as follows:
我正在尝试在 Spring MVC 控制器中实现一个方法的单元测试，如下所示：
@Test
public void testGetProfile() {
Person mockPerson = new Person();
mockPerson.setPersonId(1);
mockPerson.setName("Mr Brown");
mockPerson.setAddress("Somewhere");
mockPerson.setTelephone("1234567890");
mockPerson.setEmail("[email protected]");
when(mockPersonService.get(1)).thenReturn(mockPerson);
try {
mockMvc.perform(get("/person/profile?personId=1"))
.andExpect(status().isOk())
.andExpect(view().name("view/profile"))
.andExpect(forwardedUrl("/WEB-INF/jsp/view/profile.jsp"))
.andExpect(model().attribute("person", hasSize(1L)))
.andExpect(model().attribute("person", hasItem(
allOf(
hasProperty("personId", is(1L)),
hasProperty("name", is("Mr Brown")),
hasProperty("address", is("Somewhere")),
hasProperty("telephone", is("1234567890")),
hasProperty("email", is("[email protected]")),
)
)));
}
catch(Exception e) {
Misc.printStackTrace(e);
}
verify(mockPersonService, times(1)).get(1);
verifyNoMoreInteractions(mockPersonService);
}
But I get messages about dependencies concerning hasSize(long)and hasProperty(...).
但是我收到了关于hasSize(long)和依赖项的消息hasProperty(...)。
I have recent versions of Mockito, HamCrest et al in the application's class path.
我在应用程序的类路径中有 Mockito、HamCrest 等的最新版本。
So what am I missing?
那么我错过了什么？

Your imports only include the matchers from hamcrest-core, which are in CoreMatchers:
您的导入仅包括来自 hamcrest-core 的匹配器，它们位于CoreMatchers：
import static org.hamcrest.CoreMatchers.*;
The hasPropertyand hasSizemethods are only in the Matchersclass of hamcrest-library, which includes a larger set of matchers. Try to change your import to the following:
的hasProperty和hasSize方法仅在Matchers类hamcrest库，其包括一大组的匹配器构成。尝试将您的导入更改为以下内容：
import static org.hamcrest.Matchers.*;
If this does not work, you might only be depending on hamcrest-core. In this case, change your dependency to the hamcrest-library or hamcrest-all artifact. An example for adding this dependency for Maven is below. See the Hamcrest GitHub pagefor some more details.
如果这不起作用，您可能只依赖 hamcrest-core。在这种情况下，请将您的依赖项更改为 hamcrest-library 或 hamcrest-all 工件。下面是为 Maven 添加此依赖项的示例。有关更多详细信息，请参阅Hamcrest GitHub 页面。
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-library</artifactId>
<version>1.3</version>
</dependency>
