Android检测的单元测试将无法在一个物理设备上运行

Question

I have one device that throws an exception when I try to run unit tests on a project recently converted to use the androidX support libraries. The tests have run on emulators and other physical devices.

The device it will not run on is a Pixel 2 running 9.

App crashes with this exception:

AndroidRuntime: FATAL EXCEPTION: main

Simplified Unit Test:

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
    }
}

And the relevant dependencies:

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"

Answer 1

The provider android_support_test_services.speak_easy is obviously missing from the device. I ran the test on the working device and see that the same provider is used and found on that device. I pulled up an older branch, prior to AndroidX, ran the a instrumented test from there and then switched back, the error was gone.

Older version installed these versions:

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

Newer androidx:

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

Answer 2

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。
