android-studio - 测试运行失败 : Permission Denial: starting instrumentation ComponentInfo

Question

测试运行失败:

Permission Denial: starting instrumentation ComponentInfo{com.xxx.taskmanager.warehouse.tests/android.test.InstrumentationTestRunner} from pid=766, uid=766 not allowed because package com.xxx.taskmanager.warehouse.tests does not have a signature matching the target com.xxx.taskmanager.warehouse

空测试套件。

这是我的 app.gradle 文件

apply plugin: 'android-sdk-manager'
apply plugin: 'com.android.application'

android {
    signingConfigs {
        release
        {
            keyAlias 'xxx'
            keyPassword 'xxx'
            storeFile file('../keystore.jks')
            storePassword 'xxx'
        }
    }

    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.xxx.taskmanager.warehouse"

        versionName "3.0"
        testApplicationId "com.xxx.taskmanager.warehouse.tests"
    }

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
    }

    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            output.outputFile = new File(
                    output.outputFile.parent,
                    "FLO_HANDHELD_V${variant.versionName}.apk"
            )
        }
    }

    variantFilter { variant ->
        if(variant.buildType.name.equals('debug')) {
            variant.setIgnore(true);
        }
    }

    productFlavors {
        production_b2b {

            versionCode 3
            versionName "3.1-Prod-B2B"
        }
        stage_b2b {

            minSdkVersion 16

        }
        production_b2c {

            versionCode 3
            versionName "3.1-Stage-B2C"
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files ('libs/android-support-v7-appcompat.jar')
    compile files('libs/android-support-v4.jar')
    compile project(':taskmanagerlib')
    compile files('libs/DataCollection.jar')
    androidTestCompile fileTree(dir: 'libs', include: 'robotium-solo-5.3.0.jar')
}

task copyTask(type: Copy) {
    from 'build/outputs/apk'
    into 'apks'
    exclude '**/*-unaligned.apk'
}

task deleteApk(type: org.gradle.api.tasks.Delete){
    //    delete 'apks'
}

task appBuild(dependsOn: ['deleteApk','clean', 'assembleRelease',       'copyTask']){
    assembleRelease.mustRunAfter deleteApk
    clean.mustRunAfter deleteApk
    copyTask.mustRunAfter assembleRelease
}

我认为发生此错误是因为我尚未为测试包声明 signingConfigs。如果是这样，我如何声明它。 ?

请帮忙!!

我已经解决了这个问题。回答它，以便它对其他人有用。
解决方案适用于 Android Studio:
要运行测试，构建变体应该是调试。 Build Variants 窗口位于 android studio 的左侧，如果未激活，则通过单击 android studio 左侧的 Build variant 选项卡激活它。
