Android报告“错误=无法找到以下内容的检测信息：ComponentInfo {}”

Question

关于stackoverflow（例如Error=Unable to find instrumentation info for: ComponentInfo{ }）和其他网站上的这个问题有很多主题/问题但是让我的问题与其他人不同的是我正在研究自动化。那么让我给你更多细节。

当我在本地机器上测试时，我没有问题（我的意思是我的笔记本电脑）。我可以运行Espresso测试，所有测试都通过。

现在，我想在CI上运行这些测试（在我的案例中为Bitrise）。我创建并运行模拟器。我确认那里没有问题。我有以下脚本：

...
# Check which instrumentation packages have been installed on your device, https://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

这是CI的输出：

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)

我在defaultConfig文件的app.gradle中有以下代码行：

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

我在EditConfiguration下有android.support.test.runner.AndroidJUnitRunner，如下面的链接所示。

我想我的测试失败了，因为我的CI模拟器中没有这个命令。所以我的问题是如何通过命令行添加它？那可能吗？

Update

这是我的完整脚本。

#!/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..."

在运行“adb shell am instrument”之前，您必须安装（adb安装）和应用程序APK并测试APK（这是​​不同的APK）。
