Question

我在Android Instrument测试中使用class PostDetailView(DetailView): ...，mockito-all来模拟version: '2.0.2-beta'，这是最后一堂课

我要-

PowerManager

我的应用的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)如下-

build.gradle

我的测试用例如下-

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'
}

StackOverflow中的任何现有帖子都没有帮助，真的很感谢任何帮助

Answer 1

可以通过以下方式使用ShadowPowerManager：

  private PowerManager powerManager;
  private ShadowPowerManager shadowPowerManager;

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

Answer 2

好吧，我尝试与本地jvm一起运行

@RunWith(PowerMockRunner.class)
@PrepareForTest(PowerManager.class)
public class ExampleUnitTest2 {

    @Mock
    private Context mContext;

    @Mock
    private PowerManager mPowerManager;


    @Before
    public void setup(){
        MockitoAnnotations.initMocks(this);
        Mockito.when(mContext.getSystemService(Context.POWER_SERVICE)).thenReturn(mPowerManager);
        System.out.println("After mockedPowerManager = " + mContext.getSystemService(Context.POWER_SERVICE).hashCode());

    }
}

这是输出

After mockedPowerManager = 793319856
After mockedPowerManager = 1340086275

研究更多后，我发现-从Mockito版本开始，这是不可能的。
