我正在尝试设置Nightwatch,并且正在使用最新的chromedriver ,并说明supports chrome v52-54。但是,当我尝试运行测试时,它会说 'Error: Chrome version must be >=52.0.2743.'
以下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)
这是我的夜班人configuration file:
./ 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:

任何人都知道如何解决此错误?
Chrome version must be >= 52.0.2743.0
chromedriver是否使用我当地的chrome副本?我是否需要更新我的实际Chrome?

chromedriver是否使用我当地的chrome副本?我是否需要更新我的实际Chrome?
是的,ChromeDriver
是selenium webdriver用来控制chrome的可执行文件。
因此,selenium webdriver会在默认位置或自定义位置启动您安装的Chrome,并在初始化ChromeDriver
时告诉selenium webdriver。
所以基本上ChromeDriver
可执行文件只是用来讨论chrome浏览器和selenium webdriver来控制它,这并不意味着它启动了自己的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。
答案 1 :(得分:11)
是的,ChromeDriver使用您当地的Chrome安装。如果您不想升级Chrome安装,可以指定适用于已安装的Chrome版本的ChromeDriver版本。
您可以在https://chromedriver.storage.googleapis.com/2.25/notes.txt找到适用于不同ChromeDriver版本的兼容Chrome版本(如果您的Chrome版本比其中列出的版本更新,则将“2.25”更改为较新版本。)
如果您的测试框架使用Node.js webdriver-manager
,您只需安装所需的ChromeDriver版本(保留所有已安装的版本)(例如版本2.20
):
webdriver-manager update --chrome --versions.chrome=2.20
并在通过webdriver-manager
启动Selenium时指定相应的ChromeDriver版本:
webdriver-manager start --versions.chrome=2.20
如果webdriver-manager
不可用,您只需下载所需的ChromeDriver版本并使用某种技术将以下参数传递给Selenium服务器启动命令:
-Dwebdriver.chrome.driver=/path/to/the/desired/chromedriver_version

如果您正在使用Ubuntu 16.04,则此代码有效:
