Android Studio Robolectric Test Example

This example project shows how to use robolectric, junit and assertJ with your gradle-based Android Studio projects. Examine the top-level build.gradle and app/build.gradle files for a new project configuration gradle boilerplate.

Make sure you're running the most recent version of Android Studio from the Canary Channel for this to work correctly (1.2 Beta as of today).

To set up from a new Android Studio Project:

your top-level build.gradle file should look like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

your app/build.gradle file should look like this:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.example.joshskeen.myapplication"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    testCompile 'org.easytesting:fest:1.0.16'
    testCompile 'com.squareup:fest-android:1.0.8'
    testCompile('org.robolectric:robolectric:3.0-rc2') {
        exclude group: 'commons-logging', module: 'commons-logging'
        exclude group: 'org.apache.httpcomponents', module: 'httpclient'
    }
}

Create directories matching src/test/java/ and add a package matching your project's packagename. eg src/test/java/com.example.joshskeen.myapplication

click 'Sync Project with Gradle Files'

Select "Unit Tests" under "Build Variants"

ctrl + click on the test and select Run > MyActivityTest. Make sure you select "Gradle" test (rather than unit), indicated by the gradle icon as seen here:
