我已按照http://nightwatchjs.org/gettingstarted的步骤进行操作。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，这就是我的 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" : "",
  "globals_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 的空白选项卡会打开，控制台会显示下一个输出。

Starting selenium server... started - PID:  15024

所以， <.waitForElementVisible>没有定义。有人可以建议一个决定吗？

还有其他原因导致您的测试失败。我能够以相同的1000 ms超时时间运行您的测试，并且稍作修改即可通过。您可能想尝试增加waitForElementVisible(). 以下测试对我来说没有问题。

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();      
}

您遇到的问题不是waitForElement，也不是您的脚本的任何其他内容。之前的 setValue 与 chromeDriver 和您的浏览器的工作方式不同。这就是为什么您会看到一个选项卡打开以及为什么错误消息是关于找不到body元素的原因。

如果您更新 chromedriver，您应该能够让您的脚本正常工作。
