Android的，错误=无法找到仪器仪表信息：ComponentInfo {} [英] Android, Error=Unable to find instrumentation info for: ComponentInfo {}

问题描述

有很多话题/问题都把计算器这个问题（如错误=无法找到仪器仪表信息为：{ComponentInfo } ）等网站，但使我的问题比其他人不同的是，我自动化工作的事情。所以让我给你更多的细节。

我有，当我在本地机器上测试没有问题（我的意思是我的笔记本电脑）。我可以运行长者preSSO测试和所有测试通过。

现在，我想（在我的情况Bitrise）运行CI这些测试。我创建和运行仿真器。我确认没有问题存在。我有以下脚本：

  ...
＃检查该仪器包已安装设备，http://stackoverflow.com/a/23394559/513413上

亚行外壳上午仪器-w -r -e调试假-e类my.package.name.MyActivityTest my.package.name.test / android.support.test.runner.AndroidJUnitRunner
 

这是从我的CI输出：

我有以下code的行 defaultConfig app.gradle 文件：

  testInstrumentationRunner'android.support.test.runner.AndroidJUnitRunner
 

我 android.support.test.runner.AndroidJUnitRunner 我EditConfiguration下，你在下面的链接查看。

我猜是因为我没有在我的CI的模拟器这个命令做我的测试失败。所以我的问题是我如何可以通过命令行来添加呢？那可能吗？谢谢你。

更新

这是我的全部脚本。

解决方案

您必须安装运行亚行外壳上午仪之前（ADB安装）和应用程序APK和测试APK（这是​​不同的APK）。

There are a lot of topics/questions regard this issue on stackoverflow (such as Error=Unable to find instrumentation info for: ComponentInfo{ }) and other website but the thing that make my problem different than others is I am working on automation. So let me give you more details.

I have no problem when I'm testing on local machine (I mean my laptop). I can run Espresso testing and all tests passes.

Now, I want to run these tests on CI (Bitrise in my case). I create and run Emulator. I confirm there is no issue there. I have following script:

...
# Check which instrumentation packages have been installed on your device, http://stackoverflow.com/a/23394559/513413
echo ""
echo "Check which instrumentation packages have been installed..."
adb shell pm list instrumentation

# Running tests
echo ""
echo "running test..."
adb shell am instrument -w -r   -e debug false -e class my.package.name.MyActivityTest my.package.name.test/android.support.test.runner.AndroidJUnitRunner

This is my output from CI:

Check which instrumentation packages have been installed...
instrumentation:com.android.emulator.smoketests/android.support.test.runner.AndroidJUnitRunner (target=com.android.emulator.smoketests)
instrumentation:com.android.smoketest.tests/com.android.smoketest.SmokeTestRunner (target=com.android.smoketest)
instrumentation:com.example.android.apis/.app.LocalSampleInstrumentation (target=com.example.android.apis)
running test...
INSTRUMENTATION_STATUS: id=ActivityManagerService
INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{my.package.name.test/android.support.test.runner.AndroidJUnitRunner}
INSTRUMENTATION_STATUS_CODE: -1
android.util.AndroidException: INSTRUMENTATION_FAILED: my.package.name.test/android.support.test.runner.AndroidJUnitRunner
    at com.android.commands.am.Am.runInstrument(Am.java:1093)
    at com.android.commands.am.Am.onRun(Am.java:371)
    at com.android.internal.os.BaseCommand.run(BaseCommand.java:47)
    at com.android.commands.am.Am.main(Am.java:100)
    at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method)
    at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:251)

I have following line of code in defaultConfig of app.gradle file:

testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'

I have android.support.test.runner.AndroidJUnitRunner under my EditConfiguration as you see in the following link.

I guess my test fails because I don't have this command in my CI's emulator. So my question is how I can add it via command line? Is that possible? Thanks.

Update

This is my full script.

#!/bin/bash

# List of devices attached
adb devices

# List all *.apk files inside /bitrise/deploy path
echo "List of all *.apk files in $BITRISE_DEPLOY_DIR"
cd $BITRISE_DEPLOY_DIR && ls

# Push and Install main apk file
echo ""
echo "Pushing main apk at $BITRISE_APK_PATH to /data/local/tmp/my.package.name and install it..."
adb push $BITRISE_APK_PATH /data/local/tmp/my.package.name
adb shell pm install -r "/data/local/tmp/my.package.name"

# Push and Install Test Unaligned apk file
echo ""
echo "Pushing test unaligned apk at $BITRISE_DEPLOY_DIR/my-app-debug-unaligned.apk to /data/local/tmp/my.package.name.test and install it..."
adb push $BITRISE_DEPLOY_DIR/my-app-debug-unaligned.apk /data/local/tmp/my.package.name.test
adb shell pm install -r "/data/local/tmp/my.package.name.test"

# Check which instrumentation packages have been installed on your device, http://stackoverflow.com/a/23394559/513413
echo ""
echo "Check which instrumentation packages have been installed..."
adb shell pm list instrumentation

# Running tests
echo ""
echo "switch directory to $BITRISE_SOURCE_DIR"
cd $BITRISE_SOURCE_DIR
echo "running test..."
adb shell am instrument -w -r -e debug false -e class my.package.name.path.MinHappyPathTest my.package.name.path/android.support.test.runner.AndroidJUnitRunner

解决方案

You must install (adb install) and application APK and test APK (this is different APK) before running "adb shell am instrument".
