【问题描述】:
我正在尝试使用 @Mock 和 @Captor 注释编写测试。但是,没有创建对象,所以我得到NullPointerExceptions。
测试:
@RunWith(MockitoJUnitRunner.class)
public class ServiceTest {
@Mock
HttpClient.Builder builder;
@Mock
HttpClient client;
@Captor
ArgumentCaptor<HttpRequest> request;
MockedStatic<HttpClient> staticClient;
public MockedStatic<HttpClient> server() {
// Set up mock server
staticClient= Mockito.mockStatic(HttpClient.class);
staticClient.when(HttpClient::newBuilder).thenReturn(builder);
when(builder.build()).thenReturn(client);
return staticClient;
}
@Test
public void shouldCallService() throws IOException, InterruptedException {
try (MockedStatic<HttpClient> ignored = server()) {
HttpResponse response = mock(HttpResponse.class);
when(client.send(any(), any())).thenReturn(response);
when(response.body()).thenReturn("response");
TestService service = new TestService();
service.callService();
verify(client).send(captor.capture(), HttpResponse.BodyHandlers.ofString());
assertThat(captor.getValue().uri().getPath(), equalTo("localhost:8081"));
}
}
我的依赖是:
implementation 'org.springframework.boot:spring-boot-starter-web'
testImplementation 'org.mockito:mockito-core:3.5.11'
testImplementation "org.mockito:mockito-inline"
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.mockito', module: 'mockito-core'
}
