testing - Gradle + Robolectric + Espresso : can't run separately

Question

我尝试调整以下模板:deckard-gradle

我使用 Android Studio 0.8.14(测试版)。

这是我的 build.gradle :

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'robolectric'

android {
    compileSdkVersion 21
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 18
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        androidTest {
            setRoot('src/test')
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'LICENSE.txt'

    }
}

    androidTestCompile("junit:junit:${junitVersion}") {
        exclude module: 'hamcrest-core'
    }

    androidTestCompile("org.robolectric:robolectric:${robolectricVersion}") {

    }

    androidTestCompile 'com.squareup:fest-android:1.0.+'

    apt "org.robobinding:codegen:$robobindingVersion"
    compile("org.robobinding:robobinding:$robobindingVersion:with-dependencies") {

apply plugin: 'idea'
idea {
    module {
        testOutputDir = file('build/test-classes/debug')
    }
}

android.applicationVariants.all { variant ->
    def aptOutput = file("${project.buildDir}/generated/source/apt/${variant.dirName}")
    println "****************************"
    println "variant: ${variant.name}"
    println "manifest:  ${variant.processResources.manifestFile}"
    println "aptOutput:  ${aptOutput}"
    println "****************************"

    variant.javaCompile.doFirst {
        println "*** compile doFirst ${variant.name}"
        aptOutput.mkdirs()
        variant.javaCompile.options.compilerArgs += [
                '-processorpath', configurations.apt.getAsPath(),
                '-AandroidManifestFile=' + variant.processResources.manifestFile,
                '-s', aptOutput
        ]
    }
}

我尝试了运行单元测试的方法:

当我使用 毕业考试我收到异常，因为所有测试(也包括检测)都已执行。

当我使用 安卓工作室 运行 JUnit 测试 我收到此错误:

由于各种原因，我放弃了上述方法，转而将我的 Robolectric 测试保存在 Gradle 子模块中。你可以找到我写的一篇关于我为什么朝这个方向发展的博客文章和一个deckard-gradle项目的分支，它向你展示了here .
