Android检测的单元测试将无法在一个物理设备上运行

[英]Android instrumented unit test will not run on one physical device

当我尝试在最近转换为使用androidX支持库的项目上运行单元测试时,有一个设备引发异常。 测试已在模拟器和其他物理设备上运行。

它将无法运行的设备是运行9的Pixel 2。

应用程序因以下异常而崩溃:

简化的单元测试:

import androidx.test.rule.ActivityTestRule
import org.junit.Assert
import org.junit.Rule
import org.junit.Test

class MyTest {

    @Rule
    var activityTestRule: ActivityTestRule<AuthAppActivity> = object : ActivityTestRule<AuthAppActivity>(AuthAppActivity::class.java, false, false) {
        override fun afterActivityLaunched() {
        }

        override fun beforeActivityLaunched() {
        }
    }

    @Test
    fun runTest() {

        Assert.assertTrue(true);   // low standards here
    }
}

和相关的依赖项:

testImplementation('junit:junit:4.12') {
    exclude group: 'org.hamcrest', module: 'hamcrest-core'
}
testImplementation 'org.hamcrest:hamcrest-library:1.3'

androidTestImplementation "androidx.annotation:annotation:1.0.0"

androidTestImplementation "androidx.test:runner:1.1.0"
androidTestImplementation "androidx.test:rules:1.1.0"

androidTestImplementation 'androidx.test.uiautomator:uiautomator:2.2.0'

androidTestImplementation "androidx.test.espresso:espresso-core:3.1.0"
androidTestImplementation "androidx.test.espresso:espresso-idling-resource:3.1.0"
androidTestImplementation "androidx.test.espresso:espresso-contrib:3.1.0"
androidTestImplementation "androidx.test.espresso:espresso-web:3.1.0"
androidTestImplementation "androidx.test.espresso:espresso-intents:3.1.0"

设备显然缺少提供程序android_support_test_services.speak_easy。 我在正常运行的设备上进行了测试,发现在该设备上使用并找到了相同的提供程序。 在AndroidX之前,我拉起了一个较旧的分支,从那里运行了测试测试,然后又切换回去,错误消失了。

旧版本安装了以下版本:

test-services-1.0.2.apk
orchestrator-1.0.2.apk

较新的androidx:

orchestrator-1.1.0-alpha3.apk
test-services-1.1.0-alpha3.apk

我终于意识到我使用了旧版本的Test Orchestrator 链接后终于解决了这个问题,尽管我将所有其他测试包都更新为androidx.test ,但我不小心依赖于旧的android.support.test版本,而不是androidx.test版本。 。测试。
