Android Studio Robolectric Test Example

---

This example project shows how to do TDD by using robolectric, junit, mockito and assertJ with your gradle-based Android Studio projects.

To set up from a new Android Studio Project:

Add test dependencies on assertj-android and Robolectric to your module's build.gradle file. Your app module's app/build.gradle file would look something like this:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.joonghyup.myapplication"
        minSdkVersion 16
        targetSdkVersion 23
        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 'com.squareup.assertj:assertj-android:1.1.0'
    testCompile 'org.robolectric:robolectric:3.0'
    testCompile 'org.mockito:mockito-core:1.10.19'
}
