我正在爲使用MFP 7.1的Android項目編寫單元測試的過程，我試圖測試一些將WLResponse對象作爲輸入的功能。我想嘲笑這個對象，因爲我需要的唯一東西是JSONObject，它通過調用getResponseJSON方法返回。Mocking WLResponse爲HttpResponse拋出ClassNotFoundException
JSONObject jsonObject = Mockito.mock(JSONObject.class);
Mockito.when(jsonObject.toString()).thenReturn(person.toString());
WLResponse wlResponse = Mockito.mock(WLResponse.class);
Mockito.when(wlResponse.getResponseJSON()).thenReturn(jsonObject);
的問題是，當我打電話Mockito.mock(WLResponse.class)我得到下面的異常運行時拋出：

我使用的是通過jcenter提供的MFP 7.1 SDK，具體如下：
compile 'com.ibm.mobile.foundation:ibmmobilefirstplatformfoundation:7.1.0'
從我可以推斷，WLResponse有一個構造函數，它將一個org.apache.http.HttpResponse對象作爲參數。但是查看MFP使用的依賴關係，它依賴於android-async-http庫，而該庫又依賴於庫httpclient-android。這是第二個庫，它有第一個使用的HttpResponse類，但它所在的包是cz/msebera/android/httpclient/而不是org/apache/http/。也許這可能是錯誤的根源，因爲WLResponse的構造函數預計會改爲org.apache.http.HttpResponse，從而阻止Mockito嘲笑它。
