All the answers are good-

Make sure you have sourceSets have the test directory registered.

android{
    ...

    defaultConfig {
         ...
         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }


    sourceSets {
        androidTest {
            java.srcDirs = ['src/androidTest/java']
        }
    }
}

dependencies{
    ... 
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile 'com.android.support.test:runner:0.5'
}
