测试jersey 2客户端和webtarget

Question

我用的是jersey 2

我有一个抽象类，用来构造我的请求。现在，我还有一些抽象的客户机类，我将它们用作代理类和实际实现。这些方法工作得很好，但还没有经过测试。

我的问题是，我如何才能测试它，而不必运行它所连接的run服务？

public abstract class AbstractRestProxy {

private Client client;
private WebTarget service;

/**
 * Get the base {@link Client} and {@link WebTarget}
 */
@PostConstruct
public void base() {
    this.client = ClientBuilder.newClient();
    this.service = this.client.target(this.getBaseUri());
}

/**
 * close the connection before destroy
 */
@PreDestroy
protected void close() {
    if (this.client != null) {
        this.client.close();
    }
}

/**
 *
 * @return get the basePath
 */
protected abstract String getBasePath();

/**
 *
 * @return get the baseUri
 */
protected abstract String getBaseUri();

/**
 *
 * @param paths
 *            the paths to get for the rest service
 * @return {@link javax.ws.rs.client.Invocation.Builder}
 */
protected Builder getRequest(final String... paths) {
    WebTarget serviceWithPath = this.getServiceWithPaths();
    for (final String path : paths) {
        serviceWithPath = serviceWithPath.path(path);
    }
    return serviceWithPath.request(MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON);
}

例如，我用来获取带有标识符的响应的方法，我使用这个方法。

public Response getByID(final ID identifier) {
    return this.getRequest(identifier.toString()).get();
}

我发现这样做效果很好。因为我甚至嘲笑了响应，所以我不认为我必须关闭响应。

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClientBuilder.class)
public class AbstractGenericRestActiveProxyTest {

final Client mockClient = Mockito.mock(Client.class);
final Response mockResponse = Mockito.mock(Response.class);

private final AbstractRestProxy proxy = new AbstractRestProxy();

@Before
public void start() {
    Mockito.when(this.mockResponse.getStatus()).thenReturn(200);

    final Builder mockBuilder = Mockito.mock(Builder.class);
    Mockito.when(mockBuilder.get()).thenReturn(this.mockResponse);
    Mockito.when(mockBuilder.post(Matchers.any())).thenReturn(this.mockResponse);
    Mockito.when(mockBuilder.put(Matchers.any())).thenReturn(this.mockResponse);
    Mockito.when(mockBuilder.delete()).thenReturn(this.mockResponse);

    final WebTarget mockWebTarget = Mockito.mock(WebTarget.class);
    Mockito.when(mockWebTarget.path(Matchers.anyString())).thenReturn(mockWebTarget);
    Mockito.when(mockWebTarget.request(MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON)).thenReturn(mockBuilder);

    Mockito.when(this.mockClient.target(Matchers.anyString())).thenReturn(mockWebTarget);

    PowerMockito.mockStatic(ClientBuilder.class);
    PowerMockito.when(ClientBuilder.newClient()).thenReturn(this.mockClient);
    this.proxy.base();
}

@After
public void stop() {
    this.proxy.close();
}

@Test
public void testGetByID() {
    Mockito.when(this.mockResponse.getStatus()).thenReturn(200);

    final Response result = this.proxy.getByID(1);
    Assert.assertEquals(200, result.getStatus());
}
