android - Espresso 测试无法与 Junit5 和 multidex 一起运行

Question

我们的 espresso 测试不再运行，而它们曾经使用 Junit5。它们在从 Android Studio 4 运行时起作用，但在使用 ./gradlew app:connectedDebugAndroidTest

从 gradle CLI 运行时不起作用

他们目前失败了:

> Task :app:connectedDebugAndroidTest

我检查了 classes4.dex 是的，那个方法不在那里，但它在另一个 classes.dex 文件中。

这可能是由于:

• 迁移到 AGP 4.0
• 启用 java 8 脱糖
• 测试 apk 越来越大，因此 dex 文件拆分方式不同

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"
        [...]
    }
    [...]
}

}

和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)
    }
}

Answer 1

解决方案是显式使用 kotlin 的 jdk8 stdlib:

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