我正在努力使用Espresso在Android上进行功能测试。我的应用程序是一个Multdex应用程序,所以我按照以下链接写的说明如下:(https://developer.android.com/tools/building/multidex.html)。

我已经像这样配置了我的build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'android-apt'
def AAVersion = '3.3.2'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
}
    apt {
        arguments {
            androidManifestFile variant.outputs[0].processResources.manifestFile
            resourcePackageName 'br.com.foo'
        }
    }

    android {
        compileSdkVersion 21
        buildToolsVersion "21.1.2"
        defaultConfig {
            applicationId "br.com.foo"
            minSdkVersion 15
            targetSdkVersion 21
            android.enforceUniquePackageName = false
            multiDexEnabled true
            compileOptions {
                sourceCompatibility JavaVersion.VERSION_1_7
                targetCompatibility JavaVersion.VERSION_1_7
            }

            testApplicationId "br.com.foo.test"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
            testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
        }

        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
            }
        }

        dexOptions {
            preDexLibraries = false
            javaMaxHeapSize "4g"
        }

        packagingOptions {

            exclude 'META-INF/license.txt'
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/NOTICE.txt'
        }
    }

    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:22.1.0'}

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        apt "org.androidannotations:androidannotations:$AAVersion"

        androidTestCompile('com.android.support:multidex-instrumentation:1.0.1') {
            exclude group: 'com.android.support', module: 'multidex'
        }
    }

我从Android Studio配置了运行配置文件,将testInstrumentationRunner classe设置为com.android.test.runner.MultiDexTestRunner。

当我执行命令“ adb shell pm list instrumentation ”时,我有这个输出:

instrumentation:br.com.doe.test/com.android.test.runner.MultiDexTestRunner (target=br.com.doe)
instrumentation:br.com.foo.test/com.android.test.runner.MultiDexTestRunner (target=br.com.foo)
instrumentation:br.com.foo/com.android.test.runner.MultiDexTestRunner (target=br.com.foo)

但是当我尝试执行测试时仍然会收到此输出:

Testing started at 17:23 ...
Installing br.com.foo
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/br.com.foo"
pkg: /data/local/tmp/br.com.foo

Finish

这是我试图运行的独特测试:

package br.com.doe.inicio;

import android.support.test.InstrumentationRegistry;
import android.support.test.espresso.Espresso;
import android.support.test.espresso.action.ViewActions;
import android.support.test.espresso.matcher.ViewMatchers;
import android.support.test.runner.AndroidJUnit4;
import android.test.ActivityInstrumentationTestCase2;    
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;    
import br.com.foo.R;

@RunWith(AndroidJUnit4.class)
public class MapaEnderecoTest extends ActivityInstrumentationTestCase2<MapaEndereco>
{    
    private MapaEndereco mActivity;

    public MapaEnderecoTest()
    {
        super(MapaEndereco.class);
    }

    @Override
    @Before
    protected void setUp() throws Exception
    {
        super.setUp();
        injectInstrumentation(InstrumentationRegistry.getInstrumentation());
        mActivity = getActivity();
    }

    @Test
    public void testeAbertura()
    {
        Espresso.onView(ViewMatchers.withId(R.id.map)).perform(ViewActions.click());
    }
}

在setUp方法上的super.setUp()调用之后立即发生错误。

我有在AndroidManifest文件中注册的工具:

<instrumentation
        android:label="Multdex"
        android:name="com.android.test.runner.MultiDexTestRunner"
        android:targetPackage="br.com.foo"
        android:functionalTest="true"/>

问题在于这些gradle行:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"

你需要一个MultiDexTestRunner,但这个类派生自InstrumentationTestRunner。您的代码需要一个派生自的测试运行器AndroidJUnitRunner

解决方案是创建一个TestRunner扩展AndroidJUnitRunner和实现MultiDex代码的自定义:

import android.os.Bundle;
import android.support.multidex.MultiDex;
import android.support.test.runner.AndroidJUnitRunner;

public class TestRunner extends AndroidJUnitRunner
{
    @Override
    public void onCreate(Bundle arguments)
    {
        MultiDex.install(getTargetContext());
        super.onCreate(arguments);
    }
}

您只需添加一个引用您的自定义的Gradle行testInstrumentationRunner。这将确保构建系统生成AndroidManifest.xml使用此运行程序运行测试所需的属性。

我有类似的错误,并努力解决它。虽然接受的答案有助于OP,但它没有解决我的问题,所以我认为如果我在这里记录我的解决方案是好的,希望它也能帮助其他人。

我的问题是,我是混合AndroidJUnit4InstrumentationRegistryApplicationProviderAndroidJUnitRunner版本/包。确保它们都属于同一代。这些是使我全部运行的类:

  • androidx.test.runner.AndroidJUnitRunner
  • androidx.test.platform.app.InstrumentationRegistry
  • androidx.test.ext.junit.runners.AndroidJUnit4
  • androidx.test.core.app.ApplicationProvider

对于这些我在dependenciesbuild.gradle 的部分需要以下内容

androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
androidTestImplementation 'androidx.test:core:1.1.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation "com.android.support:support-annotations:27.1.1"
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test:rules:1.0.2'

当然是正确的

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

在我defaultConfigbuild.gradle
