使用Nightwatch的Chromedriver错误“ Chrome版本必须> = 52”

selenium

我正在尝试安装Nightwatch,并且正在使用最新的chromedriver ,它表示支持chromev52-54。但是,当我尝试运行测试时,它说
'Error: Chrome version must be>=52.0.2743.'这是我正在使用的所有内容:

项目结构

|-- nightwatch.json
|-- bin/
|   |-- chromedriver
|   |-- selenium-server-standalone-2.53.1.jar
|-- tests/
|   |-- sample.js
|-- results/
|-- screens/
|-- node_modules/
|   |-- (lots of modules here)

这是我的守夜人配置文件

./nightwatch.json

{
  "src_folders" : ["tests"],
  "output_folder" : "results",
  "custom_commands_path" : "",
  "custom_assertions_path" : "",
  "page_objects_path" : "",
  "globals_path" : "",

  "selenium" : {
    "start_process" : true,
    "server_path" : "bin/selenium-server-standalone-2.53.1.jar",
    "log_path" : "results",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "bin/chromedriver"
    }
  },

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 4444,
      "selenium_host"  : "localhost",
      "silent": true,
      "screenshots" : {
        "enabled" : true,
        "path" : "screens/"
      },
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },

    "chrome" : {
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }
}

运行测试

我像这样运行测试:

nightwatch tests/

错误

我得到以下输出:

Starting selenium server... started - PID:  3500

有人知道如何解决此错误吗?

Chrome version must be>= 52.0.2743.0

chromedriver是否使用我的本地chrome副本?我需要更新实际的Chrome吗?

chromedriver是否使用我的本地chrome副本?我需要更新实际的Chrome吗?

是的,ChromeDriver是selenium webdriver用于控制chrome的可执行文件。

因此,selenium webdriver从默认位置或自定义位置启动已安装的chrome,在初始化过程中将其告知selenium webdriver
ChromeDriver

因此,基本上
ChromeDriver可执行文件只是用来在chrome浏览器和硒webdriver之间进行对话来控制它,并不意味着它会启动自己的chrome浏览器。它使用您安装的Chrome浏览器。

是的,您需要更新实际安装的Chrome。
