无法使用NightwatchJS关闭浏览器 [英] Not able to close the browser using NightwatchJS

问题描述

我正在尝试使用Nightwatch打开URL，此后我将无法关闭浏览器.

I am trying to open my url using Nightwatch and I wan't able to close the browser afterwards.

我尝试使用超时，以及browser.end()或browser.closeWindow().他们似乎都不适合我的网址.

I tried using timeouts, as well as browser.end(), or browser.closeWindow(). None of them seem to be working for my url.

module.exports = {
  'Demo test mywrkouts' : function (browser) {
    browser.url('https://www.mywrkouts.com/workouts/search')
    browser.timeouts('script', 10000, function(result) {
    browser.end();
      console.log("Test result"+result);
    });
    //browser.closeWindow();
  }
};

它会打开页面，但不会关闭浏览器.我正在使用chromedriver的Chrome浏览器.我希望关闭该窗口，但是不起作用.

It opens the page, but doesn't close the browser. I am using Chrome browser with chromedriver. I am expecting to close the window, but it doesn't work.

任何建议都值得赞赏.

推荐答案

LE :就像我在下面广泛描述的那样， 您无需在测试结束 (通过browser.end())，因为Nightwatch测试运行程序会在每个功能文件的末尾为您执行此操作.

LE: Like I extensibly described below, you don't need to explicitly close the browser at the end of the test (via browser.end()) as the Nightwatch test-runner does that for you at the end of each feature-file.

但是，如果需要执行一些 teardown操作，然后显式关闭会话，请使用after(或afterEach)钩子进行操作.尝试以下代码段:

But, if you need to do some teardown operations and then explicitly close the session, do it in an after (or afterEach) hook. Try the following snippet:

module.exports = {

  before(browser) {
    browser.maximizeWindow();
  },

  'My Wrkouts Test': (browser) => {

    browser.url('https://www.mywrkouts.com/');
    // Check if the website logo is visible:
    browser.expect.element('#barbell-homepage-top-image-desktop img.app-bar-desktop-logo').to.be.visible;
    // Check the articles heading text:
    browser.expect.element('h3.blog-carousel-title.primary-blue-text.center').text.to.contain('Foundational Education Series');
  },

  after(browser, done) {
    browser.end(() => {
      console.info('*--*--*--*--*--*--*--*--*--*--*--*--*');
      console.info('*-- Clossing session... Good bye! --*');
      console.info('*--*--*--*--*--*--*--*--*--*--*--*--*');
      done();
    });
  }
};

无论如何，我觉得您对NightwatchJS/WebdriverIO/Protractor(或其他任何基于Webdriver的测试解决方案)处理browser会话的方式感到困惑.

Anyways, I feel you are confusing the way NightwatchJS/WebdriverIO/Protractor (or any other Webdriver-based test solution) is handling a browser session.

首先，您不必担心会关闭活动会话. Nightwatch在每个测试功能文件的末尾为您完成此操作.因此，假设运行三个测试套件(login.js，register.js，forgot_password.js)，将会依次生成&关闭三个不同的browser会话.

First off, you need not worry about closing the active session. Nightwatch does it for you at the end of each test feature-file. Thus, running a suit of let's say three test suites (login.js, register.js, forgot_password.js) will sequentially spawn & close three different browser sessions.

此外， browser.closeWindow()仅用于关闭window实例( 考虑到您有多个与同一个browser会话关联的窗口).除非您已切换到另一个window实例(在测试运行期间先前打开的 )，否则它将不会关闭主window.

Also, browser.closeWindow() is only used for closing a window instance (taking into account that you have multiple windows associated with the same browser session). It won't close your main window, unless you have switched to another window instance (which was previously opened during your test run).

如果在测试过程中使用 browser.end()，那么您基本上会终止活动会话，从而使功能文件中的以下逻辑无效:

If you use browser.end() in the middle of your test, then you basically kill the active session, nullifying the following logic from your feature-file:

INFO Request: DELETE /wd/hub/session/4a4bb4cb1b38409ee466b0fc8af78101
 - data:
 - headers:  {"Content-Length":0,"Authorization":"Basic Z29wcm86YmM3MDk2MGYtZGE0Yy00OGUyLTk5MGMtMzA5MmNmZGJhZTMz"}
INFO Response 200 DELETE /wd/hub/session/4a4bb4cb1b38409ee466b0fc8af78101 (56ms) { sessionId: '4a4bb4cb1b38409ee466b0fc8af78101',
  status: 0,
  value: null }
LOG     → Completed command end (57 ms)

之后的所有内容都将如下所示:

Everything after will look like this:

INFO Response 404 POST /wd/hub/session/null/elements (11ms) { sessionId: 'null',
  value:
   { error: 'invalid session id',
     message: 'No active session with ID null',
     stacktrace: '' },
  status: 6 }

！注意:不支持您尝试做的事情，也不是常见的用例，因此在整个过程中都缺乏对此的支持 所有这些测试解决方案.

!Note: There is no support for doing what you are trying to do, nor is it a common use-case, thus the lack of support for it across all of these testing solutions.

They say a picture is worth 1000 words, so let's me simply put it this way... what you are trying to do is synonymous with the following:
