Android Studio单元测试junit依赖项

我尝试在以下步骤中向我的AndroidStudio项目添加一些简单的Junit

我创建了/src/test/java文件夹并编写了简单的单元测试，最后添加到build.gradle文件中

问题是，当我运行测试时，由于编译器找不到org.junit.test导入，我得到了构建错误

我发现的唯一解决方案是使用 提供而不是testCompile

这是完整的gradle.build

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}
apply plugin: 'com.android.application'
repositories {
    mavenCentral()
}
dependencies {
    compile fileTree(include: '*.jar', dir: 'libs')
    compile project(':Proj1')
    compile project(':Proj2')
    compile project(':Proj3')
    provided 'junit:junit:4.12'

}

android {

    compileSdkVersion 19
    buildToolsVersion "23.0.1"

    lintOptions {
        disable 'InvalidPackage'
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }


        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }

....
}

我做错了什么？

你能发布build.gradle文件吗？您可能在那里配置了错误的存储库吗？我添加了几乎整个build.gradle文件，请查看并确保您正在将依赖项添加到正确的build.gradle，即模块中引用您的应用程序的版本。如果您需要进一步信息，请查看：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}
apply plugin: 'com.android.application'
repositories {
    mavenCentral()
}
dependencies {
    compile fileTree(include: '*.jar', dir: 'libs')
    compile project(':Proj1')
    compile project(':Proj2')
    compile project(':Proj3')
    provided 'junit:junit:4.12'

}

android {

    compileSdkVersion 19
    buildToolsVersion "23.0.1"

    lintOptions {
        disable 'InvalidPackage'
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }


        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
