Question

我在项目中使用androidx.test库（我最近迁移到了这些库），并使用了自定义AndroidJUnitRunner。在迁移之前，一切正常，但现在出现此错误-

Started running tests Test running failed: Instrumentation run failed due to 'Process crashed.' Empty test suite.

我使用的自定义跑步者类来自androidx.test.runner.AndroidJUnitRunner

在我的应用build.gradle文件中，我进行了以下设置-

testInstrumentationRunner "com.example.CustomTestRunner"

具有依赖项-

androidTestImplementation "androidx.test.ext:junit:1.1.0" androidTestImplementation 'androidx.test:runner:1.1.1' androidTestImplementation 'androidx.test:core:1.1.0' androidTestImplementation "androidx.test:rules:1.1.1"

我所有的测试班都有@RunWith(androidx.test.ext.junit.runners.AndroidJUnit4.class)

我被困在这里。任何帮助，将不胜感激。谢谢。

Answer 1

我在使用Android 4.4进行测试时看到了这一点当我切换到Android 6（SDK 23）时，问题就消失了。

我使用了androidx.test.ext.junit.runners.AndroidJUnit4 用于我的测试@RunWith（AndroidJunit4.class）

但是我的testInstrumentationRunner使用了以下软件包：

testInstrumentationRunner“ androidx.test.runner.AndroidJUnitRunner”

混合这两个不同的程序包似乎很奇怪，但是可以。

我的app / build.gradle具有：

android {
    defaultConfig {
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    testOptions { 
        execution 'ANDROIDX_TEST_ORCHESTRATOR'
        unitTests {
            includeAndroidResources = true
        }
    }

    useLibrary 'android.test.runner'
    useLibrary 'android.test.base'
    useLibrary 'android.test.mock'
}

dependencies {
    //--------------------------------------------------------------------------------

    // Mockito framework for NMEA-parser unit tests.

configurations {
    all {
        resolutionStrategy {
            force "androidx.recyclerview:recyclerview:$rootProject.ext.recyclerviewVersion"
            force "org.checkerframework:checker-qual:$rootProject.ext.checkerQualVersion"
            force "org.checkerframework:checker-compat-qual:$rootProject.ext.checkerQualVersion"
            force "com.google.errorprone:error_prone_annotations:$rootProject.ext.errorProneAnnotationsVersion"
        }
    }
}

and I have these library versions:

        // Core Test library
        testCoreVersion = '1.1.0'
        coreVersion = '2.0.0-alpha1'

        // Automated Test Libraries
        // Instrumentation Test Runner
        junitRunnerVersion = '1.1.0'
        runnerVersion = '1.1.1'
        rulesVersion = '1.1.1'
        xTruthVersion = '1.0.0'
        truthVersion = '0.42'
        espressoVersion = '3.1.0'
        hamcrestVersion = '1.3'
        orchestratorVersion = '1.1.0'

        // JUnit library version
        junitVersion = '4.12'

        // Mockito version
        mockitoVersion = '2.21.0'

        // Force testing dependencies
        recyclerviewVersion = '1.0.0'
        checkerQualVersion = '2.5.3'
        errorProneAnnotationsVersion = '2.3.1'

Answer 2

可能的原因之一是旧的 Test Orchestrator（orchestrator-1.1.1.apk） 或 Test Services（test-services- 1.1.1.apk） 应用程序，这些应用程序是为android支持库组件而构建的，仍安装在目标设备上。打开设置->所有应用，进行搜索并删除。当您再次从Android Studio运行测试时，将安装针对AndroidX构建的新应用，您的问题可能会消失。

Answer 3

在使用自定义Runner类来使用自定义Application类时，我遇到了同样的问题。

出了什么问题：

我的问题是我只传递了类的名称，而不是包+名称。

错误：

package com.teebalhoor.oredoh

import android.app.Application
import android.content.Context
import androidx.test.runner.AndroidJUnitRunner

/**
 * Created by Muhammad Maqsood on 13/09/2020.
 */
class CustomTestRunner : AndroidJUnitRunner() {

override fun newApplication(
    cl: ClassLoader?,
    className: String?,
    context: Context?
): Application {

    return super.newApplication(cl, OredohTestApplication::class.java.simpleName, context)
}
}

正确的方法：

package com.teebalhoor.oredoh

import android.app.Application
import android.content.Context
import androidx.test.runner.AndroidJUnitRunner

/**
 * Created by Muhammad Maqsood on 13/09/2020.
 */
class CustomTestRunner : AndroidJUnitRunner() {

override fun newApplication(
    cl: ClassLoader?,
    className: String?,
    context: Context?
): Application {

    return super.newApplication(cl, OredohTestApplication::class.java.canonicalName, context)
}
}

当我替换（仅提供名字）

时，工作正常

OredohTestApplication::class.java.simpleName

带有（提供软件包+名称）

OredohTestApplication::class.java.canonicalName

使用自定义运行器时未找到测试
