Question

我有一个在Jenkins管道上运行的Python脚本。该脚本读取JSON文件，然后使用ADB执行UI测试。

如果仅运行ADB命令，则该命令将成功执行。但是，当我执行管道时，会引发错误。奇怪的是，该错误是在其他打印之前记录的。。。这是怎么回事？

Jenkinsfile（的一部分）：

    stage('Generate screenshots') {
      steps {
        sh '''
cat > run_tests.py << EOF1
import json
import sys
import subprocess

screensList = sys.argv[1].split(',')

with open('results.json') as json_file:
  data = json.load(json_file)
  for screen in screensList:
    for item in data['Items']:
      if screen == item['screen']['S']:
        for test in item['android']['L']:
          testClass = test['S']
          print('Running testcase: ' + testClass)
          cmd = "/usr/local/bin/adb shell am instrument -w -r -e debug false -e executeScreenshots true -e class 'com.myproj.screenshot.TEST_CLASS' com.myproj.adhoctest.test/com.myproj.MyprojTestRunner".replace('TEST_CLASS', testClass)
          print(cmd)
          subprocess.call(cmd, shell=True)

        '''

        sh '''
function change_locale {
  echo "Changing device locale to $1"
  /usr/local/bin/adb shell "setprop persist.sys.locale $1; stop; start"
  sleep 20
}

function generate_specific_screenshots {
  change_locale $1
  python run_tests.py "$SCREENS"
}

generate_specific_screenshots $USER_LOCALE
        '''
      }
    }

测试失败，因为该应用的构建方式不正确。

要构建APK，必须使用以下命令：

./gradlew clean assembleAdhoctestDebug assembleAdhoctestDebugAndroidTest

这将生成两个APK，这两个APK必须都安装在模拟器中。

/usr/local/bin/adb root

/usr/local/bin/adb push app/build/outputs/apk/adhoctest/debug/app-adhoctest-debug.apk /data/local/tmp/com.myproj.adhoctest

/usr/local/bin/adb shell pm install -t -r "/data/local/tmp/com.myproj.adhoctest"

/usr/local/bin/adb push app/build/outputs/apk/androidTest/adhoctest/debug/app-adhoctest-debug-androidTest.apk /data/local/tmp/com.myproj.adhoctest.test

/usr/local/bin/adb shell pm install -t -r "/data/local/tmp/com.myproj.adhoctest.test"

运行调用ADB命令的Python脚本以在Jenkins中运行UI测试
