Roboelectric and Android Studio

Question

I've been trying to do it for a few days, with no result. I need to set up Robolectric in Android Studio (0.8.9, latest version). I followed different tutorials Android Unit and Integration testing, Roboelectric installation for Unit testing, Android Gradle app with Roboelectric, How to run Roboelectric JUnit tests but always got some kind of error.

So I created module specially for testing:

Kedzoh (Project) build.gradle:

// Top-level build file where you can add configuration options common to all sub-    projects/modules.
buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:0.12.+'
    classpath 'org.robolectric:robolectric-gradle-plugin:0.12.+'
}
}

allprojects {
repositories {
    jcenter()
}
}

app build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'android'

android {
compileSdkVersion 19
buildToolsVersion '19.1.0'
defaultConfig {
    applicationId 'com.dev.kedzoh'
    minSdkVersion 9
    targetSdkVersion 19
    versionCode 14
    versionName '1.6.7'
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
productFlavors {
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}
}

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

compile 'com.android.support:appcompat-v7:19.+'
compile 'com.google.android.gms:play-services:4.2.42'
compile 'com.squareup.retrofit:retrofit:1.6.1'
compile 'com.squareup.okhttp:okhttp:2.0.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
compile 'com.google.code.gson:gson:2.2.4'
compile 'com.squareup.picasso:picasso:2.3.3'
// You must install or update the Support Repository through the SDK manager to use this dependency.
compile 'com.android.support:support-v4:19.+'
compile 'com.google.guava:guava:18.0-rc1'
compile 'com.sothree.slidinguppanel:library:+'
compile 'com.larswerkman:HoloColorPicker:1.4'
}

kedzoh-tests build.gradle:

apply plugin: 'java'

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

compile 'com.squareup.retrofit:retrofit:1.6.1'
compile 'com.squareup.okhttp:okhttp:2.0.0'
compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
compile 'com.google.code.gson:gson:2.2.4'
compile 'com.squareup.picasso:picasso:2.3.3'
// You must install or update the Support Repository through the SDK manager to use this dependency.
compile 'com.google.guava:guava:18.0-rc1'
compile 'com.sothree.slidinguppanel:library:+'
compile 'com.larswerkman:HoloColorPicker:1.4'

testCompile 'junit:junit:4.+'
testCompile 'org.robolectric:robolectric:2.2'
}

At this point I cannot import Robolectric classes, it gives me error. When I add apply plugin: 'robolectric' to kedzoh-tests build.gradle, it asks for 'android' plugin. After I add it, it complains there is no Manifest and fails to build. I'm not sure that this is the right configuration, since it never worked really. Could anyone give some advice how to set Robolectric in Android Studio, please?

EDIT:

I tried the answer below, but still stuck with "Class not found" error:

There already different project templates for robolectric. Did you try https://github.com/nenick/android-gradle-template ?
