[英]Android instrumented unit test will not run on one physical device
當我嘗試在最近轉換為使用androidX支持庫的項目上運行單元測試時,有一個設備引發異常。 測試已在模擬器和其他物理設備上運行。
它將無法運行的設備是運行9的Pixel 2。
應用程序因以下異常而崩潰:
AndroidRuntime: FATAL EXCEPTION: main

AndroidRuntime: java.lang.IllegalStateException: Call to getContentProviderExternal for: android_support_test_services.speak_easy returns null!

簡化的單元測試:
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
}
}
和相關的依賴項:
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"
設備顯然缺少提供程序android_support_test_services.speak_easy。 我在正常運行的設備上進行了測試,發現在該設備上使用並找到了相同的提供程序。 在AndroidX之前,我拉起了一個較舊的分支,從那里運行了測試測試,然后又切換回去,錯誤消失了。
舊版本安裝了以下版本:
test-services-1.0.2.apk
orchestrator-1.0.2.apk
較新的androidx:
orchestrator-1.1.0-alpha3.apk
test-services-1.1.0-alpha3.apk
我終於意識到我使用了舊版本的Test Orchestrator 鏈接后終於解決了這個問題,盡管我將所有其他測試包都更新為androidx.test
,但我不小心依賴於舊的android.support.test
版本,而不是androidx.test
版本。 。測試。
