试图在移动设备中使用设备农场来实现Web应用测试自动化。源代码测试是用nightwatch.js编写的。
以下是nightwatch的配置。
{
custom_assertions_path: 'custom-assertions',
test_settings: {
default: {
selenium: {
start_process: false,
port: 4723,
host: "localhost",
silent: true,
},
android: {
desiredCapabilities = {
browserName: "Chrome",
platformName: "Android",
platformVersion: "7.0",
device: "Android",
deviceName: "Pixel 2",
avd: "Pixel_2_API_24",
}
}
}
使用模拟器，测试在本地运行正常
但在设备农场中得到以下错误信息。Nightwatch not able to connect to appium(ECONNREFUSED).

是否有遗漏的Nightwatch和设备场的配置？
你能不能尝试用start_process.True重新运行它，并验证一下端口是否没有被打开。True的情况下重新运行，并检查端口是否还没有被使用。
问题是由于一段代码在测试开始前杀死了chrome webdriver进程，杀死webdriver不会在模拟器上造成任何问题，所以在设备农场中运行测试时，必须禁止杀死webdriver进程。
