Robolectric中的资源NotFoundException

Question

由于我将项目迁移到Android Studio，因此当我想运行测试时出现以下错误：

Process finished with exit code 255

我的测试类看起来像这样：

@Config(manifest = C.MANIFEST, emulateSdk = 18, reportSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class JSONDataHelperTest {...}

有什么想法吗？

================更多信息==================

我正在使用

• Android Studio 1.1 Beta 4
• Roboletric 2.4
• com.android.tools.build:gradle:1.0.1
• com.github.jcandksolutions.gradle：机器人单元测试：2.1.1
• org.robolectric：robolectric-gradle这个-插件：0.12 +

我的项目结构（模块）：

1. app：主应用
2. robolectric-tests：测试类

我的robolectric-tests build.gradle：

evaluationDependsOn(':app')
apply plugin: 'java'

repositories {
    mavenCentral()

    def androidHome = System.getenv("ANDROID_HOME")
    // check that androidHome points to the android home dir
    println("android home dir: "+androidHome)

    maven {
        url "$androidHome/extras/android/m2repository/"
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    def androidModule = project(':app')
    compile androidModule

    println "androidModule classpath: "+androidModule.android.applicationVariants.toList().first().javaCompile.classpath
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.classpath
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.outputs.files
    testCompile files(androidModule.plugins.findPlugin("com.android.application").getBootClasspath())

    //testCompile 'junit:junit:4.12-beta-2'
    testCompile 'org.robolectric:robolectric:2.4'
    testCompile 'org.mockito:mockito-core:1.10.8'
    testCompile 'org.assertj:assertj-core:1.7.0'
    testCompile 'com.squareup:fest-android:1.0.8'
}



//prevent the "superClassName is empty" error for classes not annotated as tests
tasks.withType(Test) {
    scanForTestClasses = false
    include "**/*Test.class" // whatever Ant pattern matches your test class files
}

错误消息看起来没有找到资源;）显示string.xml中的内容

让我们开始..

  

com.github.jcandksolutions.gradle：机器人单元测试：2.1.1

此插件支持显式在同一模块中进行测试

• 应用
  • 的src /主/ JAVA
  • 的src /测试/ JAVA

对于额外的测试模块，您必须使用不同的插件来支持robolectric。您还可以使用jcandksolutions插件获得额外的测试模块，但这更像是应用程序 - >库关系，而不是test-＆gt;应用程序/库。

  

testCompile androidModule.android.applicationVariants.toList（）。first（）。javaCompile.classpath   testCompile androidModule.android.applicationVariants.toList（）。first（）。javaCompile.outputs.files   testCompile文件（androidModule.plugins.findPlugin（＆＃34; com.android.application＆＃34;）。getBootClasspath（））

很好的尝试，但我想这不会给你所有的课程和资源。这行不是eval你将使用的插件。

现在......

问题是你应该如何预测结构外观？在单独的模块中进行测试对您来说很重要吗？

使用分开的测试模块使用https://github.com/novoda/gradle-android-test-plugin。 对于一个模块保留jcandksolutions，或者您也可以尝试robolectric团队的插件https://github.com/robolectric/robolectric-gradle-plugin

所有插件都有如何使用它们的示例：

• https://github.com/JCAndKSolutions/android-unit-test/tree/master/example
• https://github.com/novoda/gradle-android-test-plugin/tree/master/sample-test
• https://github.com/robolectric/deckard-gradle

对于Android Studio的1.0版本，我推荐使用jcandksolutions，因为它可以更好地集成到Android Studio中。

使用Android Studio 1.1 Beta，您可以避免使用任何此类插件，或使用robolectric团队的当前主控。
