使用Robolectric对Android应用进行单元测试

Google提供了Android Testing framework，但是需要模拟器或者真机去跑，速度较慢。要做纯净的unit test，项目代码里面又有很多Android API的依赖，太难测。上网搜了一下，要将java的code和Android的code区分开，好像只有Robolectric能做到。

两篇参考文章

http://stackoverflow.com/questions/14949480/android-unit-test-case-automation-robolectric-library-vs-android-testing-framew

http://simpleprogrammer.com/2010/07/27/the-best-way-to-unit-test-in-android/

Robolectric搭建：（官网参考）

1. 创建一个test project。

2. 将android.jar (API 17)和robolectric-2.4-jar-with-dependencies.jar添加到libs。（运行测试时会自动下载测试依赖的jar包，文件保存在maven仓库。）

3. 选择test project的properties > Java Build Path > Projects > Add要测试的project。

4. 选择Libraries，添加上面两个jar和JUnit 4。

5. 运行测试用例的时候选择Run Configurations > Arguments > Working directory > Other > Workspace，选择待测project。这是为了解决找不到AndroidManifest.xml的错误提示。

做了demo，跑通了。

package com.mstr.robolectric;

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 org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;

import android.widget.Button;

import com.example.trasparentdialogactivity.R;
import com.example.trasparentdialogactivity.TransparentDialogActivity;

@Config(emulateSdk = 17)
@RunWith(RobolectricTestRunner.class)
public class TestDemo {

    private TransparentDialogActivity activity;

    @Before
    public void setup()
    {
        this.activity = Robolectric.buildActivity(TransparentDialogActivity.class).create().get();
    }

    @Test
    public void shouldHaveHappySmiles() throws Exception
    {
        Button startSVButton =(Button) activity.findViewById(R.id.startSVButton);
        String startSVButtonText = startSVButton.getText().toString();
        assertThat(startSVButtonText, equalTo("startSV"));

        String hello = this.activity.getPackageName();
        assertThat(hello, equalTo("Hello world!"));
    }

}

为产品项目建了个类似的test project，却总提示缺少Missing required <application/> element in xxxxxx AndroidManifest.xml。这些xml文件都是依赖项目中的，每次运行测试Robolectric都会去check哪些library projects。Google了一把，找到了一个workround。（链接）

MapzenAndroidManifest.java文件直接粘过来，改下package就好。

两个文件加到test project，再跑测试的话这个错误就不会出现了。

多项目依赖解决了，但又遇到找不到library project中的native library，也就是.so文件。报错为：

Google到一个答案（链接），但是好像是1.x版本的，2.x的没人回答，暂时先放这儿了。
