当 appium 在 Ruby 中使用单独的方法启动时，Appium 1.3.7 未启动 android 模拟器

Question

正在使用 appium 1.3.7 appium_lib 6.0.0 ruby2.0.0p451 铬驱动程序 2.15.322448 watir-webdriver 0.6.10（来自 gem 列表） selenium-webdriver 2.45.0（来自 gem 列表） Win 7 企业版 64 位 SP 1

这个有效：

def run
    end_processes('adb.exe', 'node.exe', 'emulator-arm.exe', 'emulator-x86.exe')

    # start_appium
    debug_to_log("#{Dir.pwd.chomp}")
    log_file = File.join(Dir.pwd.chomp, 'log', "#{@myName}_appium_#{@start_timestamp.strftime("%Y%m%d%H%M%S")}.log")
    command  = "appium --log-timestamp --log #{log_file}"
    debug_to_log(command)
    appium = IO.popen(command) 
    debug_to_log("Appium PID: #{appium.pid}")
    3.times { debug_to_log(appium.readline.chomp) }

    browser = open_browser_mobile("", "android emulator")
    debug_to_log("#{browser.driver.capabilities.to_yaml}")

    go_to_url(browser, "https://hxbbfb75.etforge.com/2.6.0rc6/examples/index.html")
    . . .
    browser.close if browser
    end_processes('adb.exe', 'node.exe', 'emulator-arm.exe', 'emulator-x86.exe')
end

def open_browser_mobile(device_id, device_type, ios_version='8.1')

    desired_caps = set_mobile_capabilties(device_id, device_type, ios_version)

    server_url     = "http://127.0.0.1:4723/wd/hub"
    client         = Selenium::WebDriver::Remote::Http::Default.new
    client.timeout = 300
    debug_to_log(desired_caps.to_yaml)
    Watir::Browser.new(:chrome, # :remote,
                   :url                  => server_url,
                   :desired_capabilities => desired_caps,
                   :http_client          => client
    )
end

这不是：

def start_appium
    debug_to_log("#{Dir.pwd.chomp}")
    log_file = File.join(Dir.pwd.chomp, 'log', "#{@myName}_appium_#{@start_timestamp.strftime("%Y%m%d%H%M%S")}.log")
    command  = "appium --log-timestamp --log #{log_file}"
    debug_to_log(command)
    appium = IO.popen(command) # --log-no-colors --log-timestamp  --log appium_log.txt  , :err => :out
    debug_to_log("Appium PID: #{appium.pid}")
    3.times { debug_to_log(appium.readline.chomp) }
    appium
end

def run
  end_processes('adb.exe', 'node.exe', 'emulator-arm.exe', 'emulator-x86.exe')

  start_appium

  browser = open_browser_mobile("", "android emulator")
  . . .
end

appium 启动代码是相同的...如果它包含在一个方法中并被调用，webdriver 会尝试立即启动并因 ECONNREFUSED 而失败。如果代码在启动 webdriver 的同一个方法中，它会等待 appium 服务器启动模拟器，等待浏览器打开等......行为正确。

失败实例中的appium日志是这样的（完整）。请注意，它过早结束，即根本没有显示错误：

When it succeeds the log looks like this:

Answer 1

我没有 Appium，所以这是一个猜测，但请尝试等待命令完成：

appium = IO.popen(command) 
Process.wait(appium.pid)

我认为您需要这样做，因为：

IO.popen 不等待子进程完成。
启动 Appium 的时间大于完成 start_appium 方法和垃圾收集创建的 IO 的时间。
