我尝试运行单元测试，但出现错误
错误：程序包android.support.test不存在
我的成绩档案中有
testImplementation 'junit:junit:4.12'
androidTestCompile 'junit:junit:4.12'
testCompile 'junit:junit:4.12'
但是我仍然会出错

确保您的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'
...
}
现在可以使用吗？

在示例2的gradle文件中，用实现替换androidTestImplementation似乎可以解决此问题。检查并更新一次。

像波纹管一样使用：
dependencies.gradle：

还有build.gradle(project...：
buildscript {
apply from: rootProject.file('dependencies.gradle')
repositories {
jcenter()
google()
maven {

}
}

}
}
allprojects {
repositories {
google()
jcenter()
mavenCentral()
maven { url 'https://maven.google.com' }
}
apply from: rootProject.file('dependencies.gradle')
}
task clean(type: Delete) {
delete rootProject.buildDir
}
还有build.gradle(Module...：

}
注意此行：
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

如果使用Context等Android功能，则需要将测试文件放在androidTest目录中，并用@RunWith(AndroidJUnit4.class)注释该类。
