使用Robolectric运行Android Lollipop Appcompat问题 [英] Android Lollipop Appcompat problems running with Robolectric

问题描述

由于使用了Android Lollipop，因此在使用新的Appcompat支持库时，我无法运行Robolectic测试.我关注了:

I'm not able to run Robolectic test when using new Appcompat support library available since Android Lollipop came out. I've followed:

• https://github.com/robolectric/deckard-gradle
• https://chris.banes.me/2014/10/17/appcompat-v21/

• https://github.com/robolectric/deckard-gradle
• https://chris.banes.me/2014/10/17/appcompat-v21/

可在此处获得我当前的进度: https://github.com/fada21/android- tdd-bootstrap

My current progress is available here: https://github.com/fada21/android-tdd-bootstrap

我的配置(已提取)是:

My configuration (distilled) is:

android {
  compileSdkVersion 21
  buildToolsVersion "21.0.1"

defaultConfig {
  applicationId "com.fada21.android.bootstrap"
  minSdkVersion 15
  targetSdkVersion 21

...

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:support-v4:21.0.0'
  compile 'com.android.support:appcompat-v7:21.0.0'

...

androidTestCompile('org.robolectric:robolectric:2.4-SNAPSHOT') {

这是我遇到的错误:

推荐答案

注意:从15年7月7日起，

NOTE: As of 7/7/15, Roboelectric 3.0 has been released. It solves the problem in question making this answer no longer necessary.

旧答案:

直到Robolectric 3.0出现，这是一个解决方法.

Until Robolectric 3.0 comes out, here's a fix.

#/app/src/main/res/values/styles.xml
<resources>

    //<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        //<!-- Customize your theme here. -->
    </style>


    //<!-- Hack for Robolectric to run with appcompat.v7 -->
    <style name="RoboAppTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar">
        //<!-- Customize your theme here. -->
    </style>

</resources>

然后调整您的自定义RobolectricRunner类

And then adjust your custom RobolectricRunner class

public class MyRobolectricTestRunner extends RobolectricTestRunner {
    private static final int MAX_SDK_SUPPORTED_BY_ROBOLECTRIC = 18;

    public MyRobolectricTestRunner(Class<?> testClass) throws InitializationError {
        super(testClass);
    }

    @Override
    protected AndroidManifest getAppManifest(Config config) {
        String manifestProperty = "../app/src/main/AndroidManifest.xml";
        String resProperty = "../app/src/main/res";
        return new AndroidManifest(Fs.fileFromPath(manifestProperty), Fs.fileFromPath(resProperty)) {
            @Override
            public int getTargetSdkVersion() {
                return MAX_SDK_SUPPORTED_BY_ROBOLECTRIC;
            }

            @Override
            public String getThemeRef(Class<? extends Activity> activityClass) {
                return "@style/RoboAppTheme";
            }
        };
    }
}

基本上，我们只是在告诉JVM使用不同的应用程序主题.然后像通常使用@RunWith(MyRobolectricTestRunner.class)一样使用此TestRunner.

Basically we are just telling the JVM to use a different app theme. Then use this TestRunner like you normally would with @RunWith(MyRobolectricTestRunner.class).

注意: 这解决了仅extend Activity的活动，extend ActionBarActivity

Note: This addresses activities that only extend Activity, other issues of the same type occur for activities that extend ActionBarActivity

编辑:从15年4月7日开始，Robolectric 3.0快照构建可用，占ActionBarActivity.在评论中的链接中提供了更多信息

As of 4/7/15, Robolectric 3.0-snapshot build is available which accounts for ActionBarActivity. More information is available in the links in the comments
