在Android上使用robolectric發生錯誤

我是android開發新手。學習最佳測試實踐。我下載了Robolectric 2.2。我爲Android附帶的Spinner示例寫了一個簡單的測試。我得到一個異常。我按照robolectric上的步驟在日食中進行設置。謝謝你的幫助。在Android上使用robolectric發生錯誤

測試代碼：

package com.example; 

import com.android.example.spinner.R; 
import com.android.example.spinner.SpinnerActivity; 

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.robolectric.RobolectricTestRunner; 

import android.widget.AdapterView.OnItemClickListener; 
import android.widget.Spinner; 

import junit.framework.Assert; 

@RunWith(RobolectricTestRunner.class) 
public class SpinnerActivityTest { 
    private static final String tag = "SpinnerActivityTest"; 

    @Test 
    public void spinnerShouldHaveOnClickListener() throws Exception { 
     SpinnerActivity spinnerActivity = new SpinnerActivity(); 

     Spinner spinner = (Spinner)spinnerActivity.findViewById(R.id.Spinner01); 
     OnItemClickListener onItemClickListener = spinner.getOnItemClickListener(); 
     Assert.assertTrue(onItemClickListener != null); 
    } 

}

例外：

你解決了這個問題嗎？ –

由於Robolectric 2你必須要對你有Robolectric.buildActivity（）活動

：

Activity activity = Robolectric.buildActivity(SpinnerActivity.class).attach().create().start().resume().visible().get();

欲瞭解更多信息請參閱這裏：http://robolectric.org/activity-lifecycle.html
