错误 java.lang.RuntimeException：存根！在 Android 中使用 Fitnesse 测试

我正在尝试使用创建一个测试装置Fitnesse框架，我想测试一个从服务器检索数据的函数（RESTFUL 服务）。我的测试用例非常简单：

public class FriendListActivityFixture extends ColumnFixture {
    public int URL;
    public String test() {
    JSONArray array = JsonHelper.getJsonArrayFromUrl("http://107.22.209.62/android/get_users.php");
    return array.toString();
    }
}

public static JSONArray getJsonArrayFromUrl(String url) {
        InputStream input = null;
        String result = "";
        JSONArray jsonArray = null;
        try {
            HttpClient httpclient = CustomHttpClient.getHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            input = entity.getContent();
        }
        catch (Exception e) {
            Log.e(TAG + ".getJsonArrayFromUrl(String url)", "Error in http connection " + e.toString()); 
        }

        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(input, "iso-8859-1"), 8);
            StringBuilder content = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                content.append(line + "\n");
            }
            input.close();
            result = content.toString();
        }
        catch (Exception e) {
            Log.e(TAG + ".getJsonArrayFromUrl(String url)", "Error parsing result " + e.toString());
        }

        try {
            jsonArray = new JSONArray(result);
        }
        catch (JSONException e) {
            Log.e(TAG + "getJsonArrayFromUrl(String url)", "Error converting data " + e.toString());
        }
        return jsonArray;
    }

这是Fitnesse测试页：!路径fitnesse.jar

!path C:\Program Files (x86)\Android\android-sdk\platforms\android-10\android.jar
!path C:\Users\chan\git\Spotr\Spotr\bin\classes

!|com.csun.spotr.fitnesse.FriendListActivityFixture|
|URL|test?|
|0|"wwa"|

由于这只是一个演示，我的测试目前看起来可能有点愚蠢。不幸的是，我不断收到这些错误：

我不知道它在告诉我什么？我写了其他测试方法，例如add(), substract()，一切正常。我想知道这个错误是否涉及在主线程上运行长任务？任何想法？

android.jar仅包含类的存根实现。它为您提供了构建应用程序的方法，一旦您拥有 APK，您必须在 Android 设备或模拟器上运行它。

如果我没记错的话，你正在尝试在主机的 JVM 上运行。
