【问题描述】：

我面临的问题是我无法使用 FastLane 运行 espresso 测试，我想做的是通过 Fastlane 插件在模拟器中运行测试

我使用了Fastlane的automated_test_emulator_run插件，我按照本文中的步骤https://medium.com/pink-room-club/android-continuous-integration-using-fastlane-and-circleci-2-0-part-i-7204e2e7b8b

现在，我只想在本地运行测试，所以当我运行以下命令时

bundle exec Fastlane instrumentation_tests

失败并出现错误：没有这样的文件或目录 - /tools/bin/avdmanager

这是我的快车道

default_platform(:android)

platform :android do
desc "Runs all the tests"
lane :test do
gradle(task: "test")
end

#for increment the version code
android_get_version_code(
gradle_file: "app/build.gradle" # optional
)

android_set_version_code(
gradle_file: "app/build.gradle" # optional
)

desc "Run instrumentation tests"
lane :instrumentation_tests do
automated_test_emulator_run(
AVD_setup_path: "fastlane/AVD_setup.json",
AVD_recreate_new: false,
AVD_clean_after: false,
gradle_task: "connectedDebugAndroidTest")
end
end

这是我的 AVD_setup.json

"avd_list": [
  
    "avd_name": "Pixel_2_API_Test",

    "create_avd_package": "system-images;android-28;google_apis_playstore;x86",
    "create_avd_device": "Pixel 2",
    "create_avd_tag": "google_apis_playstore",
    "create_avd_abi": "x86",
    "create_avd_additional_options": "",
    "create_avd_hardware_config_filepath": "",

    "launch_avd_port": "",
    "launch_avd_snapshot_filepath": "",
    "launch_avd_launch_binary_name": "emulator",
    "launch_avd_additional_options": "-skin 1080x1920 -gpu on"
  
]

这是输出的一部分和我得到的错误

我不知道该怎么办？我错过了什么？错误提到这可能是由于fastlane的目录处理所以我去了链接但不明白该怎么做？！我正在使用更新的 fastlane 和插件，请帮助我并提前感谢

【参考方案1】：

忽略有关目录处理的标准 fastlane 错误消息。

这是您正在使用的插件（来自我的谷歌搜索的https://github.com/AzimoLabs/fastlane-plugin-automated-test-emulator-run - 您实际上并没有提供有关此的更多信息）、它尝试使用的命令/程序（/tools/bin/avdmanager list avd）和您本地 Android 之间的事情安装。

您应该了解您的本地 Android 是否真的有 avdmanager 命令及其所在的位置，以及 list avd 是否可以使用它。然后找出插件没有从正确的位置使用它的原因。

预感：可能是插件使用了 ENV 变量 ANDROID_HOME 或您系统上为空的类似变量。

【讨论】：

哈，太棒了！您可以为插件创建一个问题，以便在 ENV 变量丢失或为空时输出错误消息。
