Espresso测试无法与Junit5和multidex一起运行。

Question

我们的浓缩咖啡测试无法运行，尽管它们曾经在Junit5上运行。当从Android Studio 4运行它们时，它们可以正常工作，但是使用./gradlew app:connectedDebugAndroidTest命令行界面（CLI）时则无法工作。

目前出现以下错误：

> Task :app:connectedDebugAndroidTest

我检查了 classes4.dex，发现该方法不存在，但它在另一个 classes.dex 文件中。

可能是以下任何原因导致的:

• 迁移到AGP 4.0
• 启用Java 8解糖
• 测试apk变得更大，因此dex文件分割方式不同

这是我们的设置：

app/build.gradle:

android {
    compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = "1.8"
        [...]
    }

    defaultConfig {
        testInstrumentationRunner "com.bonial.framework.utils.CustomEspressoTestRunner"
        testInstrumentationRunnerArgument "runnerBuilder", "de.mannodermaus.junit5.AndroidJUnit5Builder"
        [...]
    }
    [...]
}

dependencies {
   [...]

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

    androidTestImplementation "androidx.test:rules:${versions.supportTestVersion}"
    androidTestImplementation("com.schibsted.spain:barista:${versions.barista}") {
        exclude group: 'org.jetbrains.kotlin'
    }
    androidTestImplementation "com.beust:klaxon:${versions.klaxon}"
    androidTestImplementation "org.yaml:snakeyaml:${versions.snakeyaml}"
    androidTestImplementation "androidx.test.espresso:espresso-core:${versions.espresso}"
    implementation "androidx.test.espresso:espresso-idling-resource:${versions.espresso}"
    // To be able to honor espresso-contrib dependencies, our support library dependencies must match espresso's

        exclude group: 'com.android.support', module: 'support-v4'
        exclude group: 'com.android.support', module: 'appcompat-v7'

        exclude group: 'com.google.code.findbugs', module: 'jsr305'
        exclude module: 'recyclerview-v7'
    }
    androidTestImplementation("org.junit.platform:junit-platform-suite-api:${versions.junitPlatform}")
    androidTestImplementation("org.junit.platform:junit-platform-runner:${versions.junitPlatform}")

    androidTestImplementation "com.squareup.rx.idler:rx2-idler:${versions.rxIdler}"
    androidTestImplementation "androidx.core:core:${versions.coreKtx}"

}

还有 CustomEspressoTestRunner.kt：

@Suppress("unused")
class CustomEspressoTestRunner : AndroidJUnitRunner() {

    override fun onCreate(arguments: Bundle?) {
        MultiDex.install(getTargetContext())
        StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder().permitAll().build())
        super.onCreate(arguments)
    }

    @Throws(InstantiationException::class, IllegalAccessException::class, ClassNotFoundException::class)
    override fun newApplication(cl: ClassLoader?, className: String?, context: Context?): Application? {
        return super.newApplication(cl, EspressoTestApplication::class.java.name, context)
    }
}

我也遇到了同样的问题，你解决了吗？ - Shah

Answer 1

对于遇到同样问题的其他人，将我的minSdk更新为大于或等于24的值可以解决此问题。

Answer 2

解决方案是明确使用Kotlin的JDK8 stdlib：

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:${versions.kotlin}"
