Question

我是Android开发的新手。学习最佳测试实践。我下载了Robolectric 2.2。我为随附android的Spinner示例编写了一个简单的测试。我得到一个例外。我按照robolectric上的步骤在eclipse中设置它。谢谢你的帮助。

测试代码：

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：

从Robolectric 2开始，您必须使用Robolectric.buildActivity（）开始您的活动：

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