android - CircleCI 上的 Espresso 测试失败

Question

我正在尝试在 CircleCI 上运行 Android 项目仪器测试。它们在本地机器上执行良好，无论是从 Android Studio 还是命令行。 CircleCI 执行为每个测试生成此堆栈跟踪:

java.lang.RuntimeException: Waited for the root of the view hierarchy to have window focus and not be requesting layout for over 10 seconds. If you specified a non default root matcher, it may be picking a root that never takes focus. Otherwise, something is seriously wrong. Selected Root:
Root{application-window-token=android.view.ViewRootImpl$W@677cf28, window-token=android.view.ViewRootImpl$W@677cf28, has-window-focus=false, layout-params-type=1, layout-params-string=WM.LayoutParams{(0,0)(fillxfill) sim=#100 ty=1 fl=#81810100 wanim=0x1030466 surfaceInsets=Rect(0, 0 - 0, 0) needsMenuKey=2}, decor-view-string=DecorView{id=-1, visibility=VISIBLE, width=480, height=800, has-focus=true, has-focusable=true, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=2}}
. All Roots:
Root{application-window-token=android.view.ViewRootImpl$W@677cf28, window-token=android.view.ViewRootImpl$W@677cf28, has-window-focus=false, layout-params-type=1, layout-params-string=WM.LayoutParams{(0,0)(fillxfill) sim=#100 ty=1 fl=#81810100 wanim=0x1030466 surfaceInsets=Rect(0, 0 - 0, 0) needsMenuKey=2}, decor-view-string=DecorView{id=-1, visibility=VISIBLE, width=480, height=800, has-focus=true, has-focusable=true, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=2}}

有什么建议吗？ 以下是 circle.yml 的相关部分:

machine:
  environment:
    ANDROID_HOME: /usr/local/android-sdk-linux
    ADB_INSTALL_TIMEOUT: 8

dependencies:
  override:
    - echo y | android update sdk --no-ui --all --filter tools,platform-tools,build-tools-21.1.2,android-22,extra-google-m2repository,extra-google-google_play_services,extra-android-support
    - ANDROID_HOME=/usr/local/android-sdk-linux ./gradlew dependencies

test:
  override:
    - emulator -avd circleci-android22 -no-audio -no-window:
        background: true
        parallel: true
    - circle-android wait-for-boot
    # Build everything first
    - ./gradlew assembleDebugAndroidTest
    # Remove the look screen
    - adb shell input keyevent 82
    - sleep 5
    - ./gradlew connectedAndroidTest
    # copy the build outputs to artifacts
    - cp -r my-project/build/outputs $CIRCLE_ARTIFACTS
    # copy the test results to the test results directory.
    - cp -r my-project/build/outputs/androidTest-results/* $CIRCLE_TEST_REPORTS
    - (./gradlew assemble):
        timeout: 360

Answer 1

我已经联系了 CircleCI 支持人员，请他们创建一个带有 espresso 测试的示例项目。

所以 here it is .

它帮助了我。希望对您也有帮助。
