Question

在使用Espresso测试我的Android应用时，我注意到运行配置了chaining state的AndroidTest没有找到测试，而运行All in Module成功。

我创建了以下可重现的案例：

使用向导使用minSdk 8创建新的干净应用程序并清空活动
使用espresso依赖项等配置gradle（见下文）
使用选项All in Package创建AndroidTest Run Configuration，使用All in Module
添加带测试的课程（见下文）
使用All in Package运行：已通过测试
使用All in Package运行：未找到任何测试

使用All in Module运行直到几天前一直运行良好。我记得的更改是将Android Studio升级到1.4并将All in Module升级到23.1.0，将Android Support Library升级到24.0.0。

顺便说一下。 Android Support Repository和gradlew connectedCheck现在也失败了。

有没有人有解决此问题的建议？

build.gradle for app：

gradlew createDebugAndroidTestCoverageReport

Test.java

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.xyz.apptest"
        minSdkVersion 8
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled true
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.1') {
        // Necessary if your app targets Marshmallow (since Espresso
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
        // Necessary if your app targets Marshmallow (since Espresso
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude module: 'recyclerview-v7'
    }
    androidTestCompile('com.android.support.test.espresso:espresso-idling-resource:2.2.1') {
        // Necessary if your app targets Marshmallow (since Espresso
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test:runner:0.4.1') {
        // Necessary if your app targets Marshmallow (since the test runner
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test:rules:0.4.1') {
        // Necessary if your app targets Marshmallow (since the test runner
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'

    }
}

在运行窗口中跟踪：

@RunWith(AndroidJUnit4.class)
public class Test1 {

    @Rule
    public ActivityTestRule<MainActivity> activityTestRule =
            new ActivityTestRule<>(MainActivity.class, true, false);

    @Before
    public void setUp() {
        activityTestRule.launchActivity(new Intent());
    }

    @After
    public void cleanUp() {
    }

    @Test
    public void test() {
    }
}

logcat：未发现易受影响的差异。

从基于API 10的模拟器切换到API 17解决了这个问题。

尽管API 10在上周运行良好，但它已变得无法预测。有时它会运行，但大多数情况下都没有。删除单个测试方法可能会使其工作，将其放回可能会使其保持工作（或不工作）。试图第五次运行测试可能会再次运行...

更新2016-03-16 ：增加API 10仿真器的资源使得测试再次可用于API 10 ......
