Test support library in android studio is not compiled

Issue

I have the latest support library installed in my SDK. gradle file

        defaultConfig {
            applicationId "com.example.win.dat_2"
            minSdkVersion 19
            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']) 
        compile 'com.android.support:appcompat-v7:23.1.1'
        androidTestCompile('com.android.support.test.espresso:espres‌​so-core:2.2.2', { 
exclude group: 'com.android.support', module: 'support-annotations' }) 
    }

Solution

In app gradle add this to defaultConfig

multiDexEnabled = true
