我跟随了http://nightwatchjs.org/gettingstarted的步骤。在我的测试文件中，我有来自http://nightwatchjs.org/guide/的下一个代码
module.exports = {
'Demo test Google' : function (browser) {
browser
.url('http://www.google.com')
.waitForElementVisible('body', 1000)
.setValue('input[type=text]', 'nightwatch')
.waitForElementVisible('button[name=btnG]', 1000)
.click('button[name=btnG]')
.pause(1000)
.assert.containsText('#main', 'Night Watch')
.end();
}
};
另外，这是我的package.json的样子。
{
"name": "try_nw",
"version": "1.0.0",
"description": "try_nightwatch",
"main": "nightwatch.js",
"scripts": {
"test": "node nightwatch -e chrome"
},
"author": "",
"license": "ISC",
"dependencies": {
"bower": "^1.8.2",
"chromedriver": "^2.34.0",
"geckodriver": "^1.10.0",
"nightwatch": "^0.9.19",
"selenium-server-standalone-jar": "^3.8.1"
}
}
还有我的nightwatch.json
{
"src_folders" : ["tests"],
"output_folder" : "reports",
"custom_commands_path" : "",
"custom_assertions_path" : "",
"page_objects_path" : "",

"selenium" : {
"start_process" : true,
"start_session" : true,
"server_path" : "bin/selenium-server-standalone-3.8.1.jar",
"log_path" : "",
"port" : 4444,
"cli_args" : {
"webdriver.chrome.driver" : "bin/chromedriver.exe",
"webdriver.gecko.driver" : "",
"webdriver.edge.driver" : ""
}
},
"test_settings" : {
"default" : {
"launch_url" : "http://localhost",
"selenium_port" : 4444,
"selenium_host" : "localhost",
"silent": true,
"screenshots" : {
"enabled" : false,
"path" : ""
},
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true,
"chromeOptions" : {
"args" : ["--no-sandbox", "--start-maximized", "--disable-infobars"]
}
}
},
"chrome" : {
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true
}
},
"edge" : {
"desiredCapabilities": {
"browserName": "MicrosoftEdge"
}
}
}
}
但是，当我运行测试时，chrome的空白选项卡打开，控制台显示下一个输出。

因此，未定义<.waitForElementVisible>。任何人都可以提出决定吗？
您遇到的问题不是waitForElement，也不是每个sae脚本的任何其他问题。之前的setValue与chromeDriver和您的浏览器的工作方式不同。这就是为什么你看到一个标签打开，为什么错误信息是关于找不到body元素。
如果你更新chromedriver，你应该能够让你的脚本工作。
还有其他因素导致您的测试失败。我能够以相同的1000 ms超时运行您的测试，并且稍微修改就通过了。您可能想尝试增加waitForElementVisible()的超时。以下测试通过我没有问题。
browser
.url('http://www.google.com')
.waitForElementVisible('body', 1000)
.setValue('input[type=text]', ['nightwatch', browser.Keys.ENTER])
.pause(1000)
.assert.containsText('#main', 'Night Watch')
.end();
}
