Gradle 'Build Script error' occurs when I attempt to use testCompile in dependencies

Question

I'm working with Android Studio and in my dependencies for my application I attempting to add a testCompile dependency as listed here: http://www.gradle.org/docs/current/userguide/artifact_dependencies_tutorial.html When I sync my file I get the error: I don't understand what is going on, my gradle build file in my root folder is set to classpath 'com.android.tools.build:gradle:0.12.+' and that's the most recent version. Why doesn't it recognize testCompile? I don't want to deploy test dependencies to production... Any helps would be appreciated.

EDIT: Here is the project build file

buildscript {
    repositories {
        jcenter()


    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

and here is the src build file:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 17
    buildToolsVersion "20.0.0"
    defaultConfig {
        applicationId "com.example.edu.myApp"
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug{
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files('libs/scribe-1.3.5.jar')
    compile files('libs/json_simple-1.1.jar')
    compile 'com.google.android.gms:play-services:5.0.77'
    // Can't be higher than 19 if we want to support smaller android versions
    compile 'com.android.support:appcompat-v7:19.+'
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:support-v4:19.+'
    // This Mockito includes all dependancies (great for us)
    testCompile "org.mockito:mockito-core:1.9.+"
    testCompile 'org.hamcrest:hamcrest-all:1.3'
    testCompile 'org.objenesis:objenesis:1.2'
}

You should use androidTestCompile, not testCompile. If this is due to modifying the dependency scope via the Project Structure dialog, then there's a bug where it uses the wrong statement to set up the dependency. I've filed https://code.google.com/p/android/issues/detail?id=74771 for this.
