Robolectric 2.2 中的 android.content.res.Resources$NotFoundException

Question

我有一个带有自定义主题的 View ，如前所述here这解决了所描述的问题，但是当我在 ActivityController 上调用 visible() 时会导致以下错误。

这是包含自定义主题的 syle.xml 文件

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="android:Theme.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

<style name="Theme.RobolectricCompatible" parent="@style/Theme.Base.AppCompat.Light.DarkActionBar">
    <item name="android:windowNoTitle">false</item>
</style>

这是我设置主题的 Activity block

<activity
        android:name=".activities.LogActivity"
        android:label="@string/log_activity_title"
        android:parentActivityName="com.myApp.activities.MainActivity"
        android:theme="@style/Theme.RobolectricCompatible" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
        android:value="com.myApp.activities.MainActivity" />
</activity>

我有另一个使用 Theme.Base.AppCompat.Light.DarkActionBar 主题的 Activity，我可以正确测试它，但如果我将主题更改为 Theme.RobolectricCompatible，它会显示相同的行为。

最后，这是我运行测试时 Eclipse 输出的内容:

    DEBUG: Loading resources for com.myCompany.myApp from C:\Users\luca\Android\myAppTest\..\myApp\res...
    DEBUG: Loading resources for android.support.v7.appcompat from C:\Users\luca\Android\myAppTest\..\myApp\..\android-support-v7-appcompat\res...
    DEBUG: Loading resources for android from jar:C:\Users\luca\.m2\repository\org\robolectric\android-all\4.3_r2-robolectric-0\android-all-4.3_r2-robolectric-0.jar!/res...

请注意路径指向正确的资源目录。

在不调用 visible() 的情况下，我没有收到任何错误，但我需要测试一些在 onCreateOptionsMenu() 中初始化的 menuItem ，而这又是在 visible() 中调用(我已经尝试通过自己传递 TestMenu 对象来调用该方法，但它不起作用(并且也已弃用))

我正在使用 robolectric 2.2，但我也尝试过使用 2.3-SNAPSHOT

我真的很感激任何帮助，因为我已经没有想法了。

问题是因为您使用了支持库，而 robolectric 与其不兼容。 ActionBarSherlock 也是如此。

幸运的是问题已经解决了。这对我有用。

根据 sneuberger-amazon 在 https://github.com/robolectric/robolectric/issues/ 上的帖子:

The problem is that Robolectric provides a ShadowMenuInflater, but it does not provide a ShadowSupportMenuInflater (which is what appcompat uses).

You can fix this by creating a org.robolectric.shadows.ShadowSupportMenuInflater class with contents:

package org.robolectric.shadows;

import org.robolectric.annotation.Implementation;
import org.robolectric.annotation.Implements;

import android.support.v7.internal.view.SupportMenuInflater;
import android.view.Menu;

@Implements(SupportMenuInflater.class)
public class ShadowSupportMenuInflater extends ShadowMenuInflater {
    @Implementation
    public void inflate(int menuRes, Menu menu) {
        super.inflate(menuRes, menu);
    }
}

Put this class in your own project's org.robolectric.shadows package. That way Robolectric will find it when looking for a shadow for SupportMenuInflater, so that all your tests will get it automatically (no need to add a shadow Config to every test).
