Android - 错误 : package android. support.test 不存在

Question

我尝试运行单元测试，但出现错误

error: package android.support.test does not exist

在我的成绩文件中，我有

testImplementation 'junit:junit:4.12'
androidTestCompile 'junit:junit:4.12'
testCompile 'junit:junit:4.12'

但我仍然收到错误

确保你的 gradle 文件是这样的:

android {
    ...
    defaultConfig {
        ...
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        ...
    }
    ...
}
dependencies {
    ...
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    testImplementation 'junit:junit:4.12'
    ...
}

它现在有效吗？
