在 Android Studio 中使用 Robolectric 和 AppCompat 时找不到 StyleData 的父级

Question

我有一个Android项目，它使用:

Android Studio Gradle结构
• Android AppCompat库
• robolelectric用于测试

测试不涉及任何活动(例如，只是断言1 == 1)，工作得很好。但是，当我使用活动创建以下错误:

java.lang.RuntimeException: huh? can't find parent for StyleData{name='Theme_Sanactbar', parent='@style/Theme_AppCompat_Light_DarkActionBar'}
    at org.robolectric.shadows.ShadowAssetManager$StyleResolver.getParent(ShadowAssetManager.java:365)
    at org.robolectric.shadows.ShadowAssetManager$StyleResolver.getAttrValue(ShadowAssetManager.java:350)

我尝试https://github.com/robolectric/robolectric/issues/979，但它创建相同的结果。

Answer 1

调试完robolelectrical source后，我知道我需要创建项目。属性文件。

假设你使用的是Android Studio项目结构，文件的位置是PROJECT_X/app/src/main/project.properties

内容

android.library.reference.1=/../../../build/intermediates/exploded-aar/com.android.support/appcompat-v7/19.1.0

这是因为robolelectric的AndroidManifest.getBaseDir()给了你/path/into/AndroidStudioProjects/PROJECT_X/app/src/main。

因此，这个基本目录附加了参考位置。在这种情况下，我可以确保/path/into/AndroidStudioProjects/PROJECT_X/app/src/main + /../../../build/intermediates/exploded-aar/com.android.support/appcompat-v7/19.1.0给我一个包含appcompat库的AndroidManifest.xml的目录。

Answer 2

对我来说，有效的是更新到roboletric:2.4-SNAPSHOT，并确保您的测试类与测试类在同一个"包"中。

我的测试类也需要这个配置注释:

@Config(emulateSdk = 18, reportSdk = 18)

我不需要project.properties文件

dependencies {
    repositories {
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
    }
    androidTestCompile('org.robolectric:robolectric:2.4-SNAPSHOT') {
        //excludes here
    }
}

此外，我必须确保我在gradle中有以下任务，以避免验证错误(只有半相关)

/**
 * Fixes: https://github.com/robolectric/robolectric/issues/1186
 * Java 7 and 8 have strict compiler verification, this doesn't apply to Android
 * Our error was related to AppCompat not Play Svcs, but it was the same error
 */
tasks.whenTaskAdded { theTask ->
    def taskName = theTask.name.toString()
    if ("testDebug".toString().equals(taskName)) {
        /**
         * Listen for when robolectric adds the 'testDebug' task and when it does, add the -noverify
         * option to that task's jvmArgs.  This allows us to turn off byte code verification when
         * running our unit tests.
         */
        theTask.jvmArgs('-noverify')
    }
}
