javascript - 测试完成后 Chromedriver 不会退出

Question

我正在使用 nightwatch 框架进行测试。我已通过此命令将 selenium-server 安装到我的项目文件夹“npm install --save-dev selenium-server”中，并通过 chromedrivernpm install --save-dev chromedriver。 我使用以下命令运行测试:./node_modules/.bin/nightwatch -e chrome --tag [test name]。 我的 nightwatch.json 文件如下所示:

{
  "src_folders": [
    "tests"
  ],
  "output_folder": "reports/XMLReports",
  "custom_commands_path": [
    "commands",
    "node_modules/nightwatch-custom-commands-assertions/js/commands",
    "./node_modules/nightwatch-commands/commands"
  ],
  "custom_assertions_path": "node_modules/nightwatch-custom-commands-assertions/js/assertions",
  "page_objects_path": [
    "pages_lms",
    "pages_app"
  ],
  "globals_path": "./globalsModule.js",
  "selenium": {
    "start_process": true,
    "server_path": "./node_modules/selenium-server/lib/runner/selenium-server-standalone-3.11.0.jar",
    "log_path": "log/",
    "host": "127.0.0.1",
    "end_session_on_fail" : true,
    "port": 4444,
    "cli_args": {
      "webdriver.chrome.driver": "./node_modules/chromedriver/lib/chromedriver/chromedriver",
      "webdriver.ie.driver": "",
      "webdriver.firefox.profile": ""
    }
  },
  "test_settings": {
    "chrome": {
      "selenium_port": 4444,
      "selenium_host": "localhost",
      "silent": true,
      "screenshots": {
        "enabled": true,
        "path": "screenshots/"
      },
      "desiredCapabilities": {
        "browserName": "chrome",
        "args": [
          "disable-web-security",
          "ignore-certificate-errors",
          "--test-type "
        ]
      }
    }
  }
}

问题是每次测试后 chromedriver 都不会退出，如果我一个接一个地运行 10 个测试，我会启动 10 个 chromedriver。

如果我要添加 globals.js 文件并将路径放入我的 nightwatch.json 中:

   var chromedriver = require('chromedriver');
module.exports = {
  before : function(done) {

    chromedriver.start();

    done();
  },

  after : function(done) {
    chromedriver.stop();

    done();
  }
};  

这将打开另一个 chromedriver(这意味着两个 chromedriver 用于一次测试)，但是一个 chromedriver 将完成而另一个仍然没有。

这是一个测试的日志:

你能告诉我如何退出吗？谢谢。

你可以像这样在每个测试中调用 after 方法:

`'after' : function(browser, done) {
        browser.end(function(){
            done();
        });
    },
