Android（Mockito（2.0.2-beta） - 无法模拟/间谍最后的课程） _Android

【Android（Mockito（2.0.2-beta） - 无法模拟/间谍最后的课程）】归志宁无五亩园，读书本意在元元。这篇文章主要讲述Android：Mockito（2.0.2-beta） - 无法模拟/间谍最后的课程相关的知识，希望能为你提供帮助。
我在android Instrumented测试中使用qazxsw poi，qazxsw poi来模拟mockito-all，这是一个最后的类，
我正进入（状态 -

version: '2.0.2-beta'

我的应用程序的PowerManager如下 -

org.mockito.exceptions.base.MockitoException: Cannot mock/spy class android.os.PowerManager Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types at com.crsardar.handson.android.mockito.ExampleInstrumentedTest.useAppContext(ExampleInstrumentedTest.java:38) at java.lang.reflect.Method.invoke(Native Method) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at android.support.test.runner.AndroidJUnit4.run(AndroidJUnit4.java:101) at org.junit.runners.Suite.runChild(Suite.java:128) at org.junit.runners.Suite.runChild(Suite.java:27) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at org.junit.runner.JUnitCore.run(JUnitCore.java:115) at android.support.test.internal.runner.TestExecutor.execute(TestExecutor.java:56) at android.support.test.runner.AndroidJUnitRunner.onStart(AndroidJUnitRunner.java:384) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1932)

我的仪器测试案例如下 -

build.gradle

StackOverflow中现有的帖子都没有帮助，我们非常感谢任何帮助
答案可以通过以下方式使用ShadowPowerManager：

apply plugin: 'com.android.application'android { compileSdkVersion 26 defaultConfig { applicationId "com.crsardar.handson.android.mockito" minSdkVersion 25 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }configurations.all { resolutionStrategy { force 'com.android.support:support-annotations:26.1.0' } } }dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' implementation group: 'org.mockito', name: 'mockito-all', version: '2.0.2-beta' }

另一答案在研究了更多我发现 - 从这个版本的Mockito，它是不可能的。
另一答案好吧，我试着和当地的jvm一起跑，

package com.crsardar.handson.android.mockito; import android.content.Context; import android.os.PowerManager; import android.support.test.runner.AndroidJUnit4; import org.junit.Test; import org.junit.runner.RunWith; import static org.mockito.Mockito.mock; import static org.mockito.Mockito.when; /** * Instrumented test, which will execute on an Android device. * * @see < a href="http://d.android.com/tools/testing"> Testing documentation< /a> */ @RunWith(AndroidJUnit4.class) public class ExampleInstrumentedTest {private Context mockedContext = null; @Test public void useAppContext() {PowerManager mockedPowerManager = mock(PowerManager.class); System.out.println("Before mockedPowerManager = " + mockedPowerManager.hashCode()); mockedContext = mock(Context.class); when(mockedContext.getSystemService(Context.POWER_SERVICE)).thenReturn(mockedPowerManager); System.out.println("After mockedPowerManager = " + mockedContext.getSystemService(Context.POWER_SERVICE).hashCode()); } }

这是输出，

private PowerManager powerManager; private ShadowPowerManager shadowPowerManager; @Before public void before() { powerManager =(PowerManager)ApplicationProvider.getApplicationContext().getSystemService(Context.POWER_SERVICE); shadowPowerManager = shadowOf(powerManager); shadowPowerManager.setIsScreenOn(false); }
