Robolectricバージョン1.1を使用していますが、アクティビティにボタンがあるとテストを実行できません。

add_emoticon_activity.xml

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    >
    <Button
        android:id="@+id/addEmoticonButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/add_emoticon_button_text"
        />
</LinearLayout>

AddEmoticonActivity.java

import android.app.Activity;
import android.os.Bundle;

public class AddEmoticonActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.add_emoticon_activity);
    }
}

AddEmoticonActivityTest.java

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

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

import android.widget.Button;

import com.xtremelabs.robolectric.RobolectricTestRunner;
import com.xtremelabs.robolectric.shadows.ShadowHandler;
import com.xtremelabs.robolectric.shadows.ShadowToast;

@RunWith(RobolectricTestRunner.class)
public class AddEmoticonActivityTest {
    private AddEmoticonActivity addEmoticonActivity;
    private Button addButton;

    @Before
    public void setup() {
        addEmoticonActivity = new AddEmoticonActivity();
        addEmoticonActivity.onCreate(null);
        addButton = (Button) addEmoticonActivity.findViewById(R.id.addEmoticonButton);
    }

    @Test
    public void shouldDisplayErrorMessageWhenEmptyContentAdded() {
        addButton.performClick();

        ShadowHandler.idleMainLooper();
        assertThat(ShadowToast.getTextOfLatestToast(), equalTo(addEmoticonActivity.getResources().getString(R.string.no_content_error_message)));
    }
}

layout.xmlからボタンを削除すると、美しく機能します。

誰かが何が起こったのか知っていますか？

どうもありがとう

元の問題の原因となったNullPointerExceptionがすべて発生しているようです。

このコミットは、1.1がリリースされた後に発生し、エラーを受け取った行であるColorResourceLoader.javaの33行を変更しました。

https://github.com/pivotal/robolectric/commit/f647512bd80162f9cb6b2fac8c7b0db984266967

Robolectricの新しいバージョンにアップグレードすると、問題が解決する可能性があるようです。1.1が最新のリリースバージョンであることは知っていますが、2.0alpha1バージョンがリリースされています。
