Question

我尝试在My Windows 8计算机上设置Nightwatch.js

我安装了nodejs，nightwatch和selenium-standalone-sever 3.0.0-beta1.jar。当我尝试运行我的sample.js测试时，我收到以下错误。

Error retrieving a new session from the selenium server

Connection refused! Is selenium server started?
{ state: 'unhandled error',
  sessionId: null,
  hCode: 847580505,

     cause: null,

     class: 'java.lang.IllegalStateException',
     screen: null },
  class: 'org.openqa.selenium.remote.Response',
  status: 13 }

我的配置文件是：

{
  "src_folders" : ["tests"],
  "output_folder" : "reports",
  "custom_commands_path" :"",
  "custom_assertions_path" :"",
  "page_objects_path" :"",
  "globals_path":"",
  "selenium": {
    "start_process" : false,
    "server_path" : "",
    "log_path" : "",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "",
      "webdriver.ie.driver" : ""
    }
  },
  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_port"  : 4444,
      "selenium_host"  : "localhost",
      "silent": true,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "desiredCapabilities": {
        "browserName": "firefox",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },
    "chrome" : {
      "desiredCapabilities": {
        "browserName": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    }
  }
}

和我的sample.js文件是：

 module.exports = {
  'Demo test Google' : function (browser) {
    browser
      .windowMaximize()
      .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();
  }
};

Answer 1

所需的功能应如下所示， 但我不确定nightwatch js是否支持webdriver 3.0 。

"desiredCapabilities": {
        "browserName": "firefox",
        "javascriptEnabled": true,
        "acceptSslCerts": true,
        "marionette": true
      }

cli_arguments应该有geckodriver的路径。

"cli_args" : {
     "webdriver.gecko.driver": "<path-to-geckodriver>"
 }

您可以从此处下载geckodriver：https://github.com/mozilla/geckodriver/releases

Answer 2

您尚未启动selenium服务器。您可以手动执行此操作，或者夜间监视可以为您执行此操作

"selenium": { "start_process" : true, // let nigthwatch to start selenium server "server_path" : "./selenium-server-standalone.jar", // provide path to selenium server jar "log_path" : "", "host" : "127.0.0.1", "port" : 4444, "cli_args" : { "webdriver.chrome.driver" : "", "webdriver.ie.driver" : "" } }

Answer 3

brew install geckodriver

然后你通过

将你的驱动程序更改为firefox

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

必须通过web driver.gecko.driver系统属性设置驱动程序可执行文件的路径;夜间值班
