java单元测试模拟HttpClient和webdav

您好，我有一个用于执行webdav相关操作的类，例如创建目录，可以在下面看到实现（createDir方法）。问题是如何很好地测试它，也许可以使用EasyMock或类似的库。有什么想法吗？谢谢

package foobar;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException; 

import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.DeleteMethod;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.PutMethod;
import org.apache.commons.httpclient.methods.RequestEntity;

import org.apache.jackrabbit.webdav.client.methods.DavMethod;
import org.apache.jackrabbit.webdav.client.methods.MkColMethod;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import mypackage.httpdclient.util.URLHandler;


public class WebDavImpl{

    private static final String SEPARATOR = " ----- ";
    private HttpClient httpClient;
    public StorageSpaceClientImpl() {
        httpClient = new HttpClient();
    }

    public String createDir(String dirName) {

        String response = null;
        String url = URLHandler.getInstance().getDirectoryUrl(dirName);
        DavMethod mkcol = new MkColMethod(url);
        try {
            httpClient.executeMethod(mkcol);
            response = mkcol.getStatusCode() + SEPARATOR + mkcol.getStatusText();

        } catch (IOException ex) {

        } finally {
            mkcol.releaseConnection();
        }

        return response;
    }

   }

什么也不做的声明只是痛苦和死亡。你应该在那里做点什么，或者让异常冒泡出来。你找到创建webdav相关测试的解决方案了吗？catch语句什么都不做，只会带来痛苦和死亡。你应该在那里做点什么，否则就会出现异常。你找到创建webdav相关测试的解决方案了吗？
