问题描述
这是我正在写junit的我的实际课程.我将HtpClient设置为私有和最终版本.
This is my Actual class for which i am writing junit. I have HtpClient as private and final.
public class KMSHttpClientImpl implements KMSHttpClient
{
/**
* ObjectMapper Instance.
*/
private final ObjectMapper objectMapper = new ObjectMapper ();
/**
* KMS ConnectionManager Instance.
*/
private final KMSHttpConnectionManager kmsHttpConnectionManager =
new KMSHttpConnectionManagerImpl ();
/**
* HttpClient object.
*/
private final HttpClient httpClient;
/**
* KMSHttpClient constructor.
*/
public KMSHttpClientImpl ()
{
// TODO PoolingHttpClientConnectionManager object should be closed after use.
// TODO This needs to be either singleton or should be kept in static block
final PoolingHttpClientConnectionManager connectionManager =
kmsHttpConnectionManager.getConnectionManager();
httpClient = HttpClients.custom()
.setConnectionManager(connectionManager)
.build();
}
@Override
public <T> T invokeGETRequest (final String url, final Class<T> clazz)
throws KMSClientException
{
final HttpGet httpGet = new HttpGet(url);
try {
final HttpResponse response = httpClient.execute(httpGet);
return objectMapper.readValue(
response.getEntity().getContent(), clazz);
} catch (IOException e) {
throw new KMSClientException("Unable to get the result", e);
}
}
@Override
public <T> T invokePOSTRequest (final String url, final Object object, final Class<T> clazz)
throws KMSClientException
{
final HttpPost httpPost = new HttpPost(url);
try {
final HttpResponse response = httpClient.execute(httpPost);
return objectMapper.readValue(
response.getEntity().getContent(), clazz);
} catch (IOException e) {
throw new KMSClientException("Unable to create the request", e);
}
}
}
这是我的测试课.我正在尝试模拟HttpClient,但由于最终我无法模拟它.如果我从KMSHttpClientImpl.java类的HttpClient中删除final.我收到PMd问题说专用字段"httpClient"可以设为最终值;它仅在声明或构造函数中初始化.我该怎么做才能解决此问题?
This is my testclass. I am trying to Mock HttpClient but as it is final i cant mock it. And if i remove final from HttpClient in my KMSHttpClientImpl.java class. I am getting PMd issue sayingPrivate field 'httpClient' could be made final; it is only initialized in the declaration or constructor. What can i do to fix this issue?

推荐答案
测试HTTP客户端代码的一种方法是不模拟您的HTTPClient对象,而是为http调用创建模拟响应,然后让您的HPPTClient拨打这些网址.看看Wiremock. http://wiremock.org/docs/它可以帮助您创建一个简单的模拟服务器,并且可以对URL的响应进行存根.然后使用客户端进行测试来调用您的URL.
One of the ways to test a HTTP client code would be to not mock your HTTPClient object, but to create mock responses for the http calls and then let your HPPTClient make calls to those URLs.Take a look at Wiremock. http://wiremock.org/docs/It helps you create a simple mock server and you can stub responses for your URLs.Then invoke your URLs using your client for the test.
