我收到“java.lang.运行时异常：Stub！”。我有正确的eclipse顺序，也正确地设置了运行程序。这是堆栈跟踪。

这是我的试卷

package com.example.sample.test;

import static org.hamcrest.CoreMatchers.equalTo;
import static org.junit.Assert.assertThat;

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

import com.example.sample.MainActivity;
import com.example.sample.R;

@RunWith(RobolectricTestRunner.class)
public class MyActivityTest {
    private MainActivity activity;

    @Test
    public void shouldHaveHappySmiles() throws Exception {
        String hello = new MainActivity().getResources().getString(R.string.hello_world);
        assertThat(hello, equalTo("Hello world!"));
        activity = Robolectric.buildActivity(MainActivity.class)
                .create().get();
    }
}

我写这个测试用例只是为了和Roboelectric混在一起。
