nightwatch.js - 为什么 Nightwatch.js 测试在 CircleCI 上失败？

我使用 Nightwatch.js 设置了一个简单的 smoketest。他们在本地通过，但在 CircleCI 上失败。

源代码:

const WAIT = 1000;
const NODE_PORT = process.env.NODE_PORT || 3000;

module.exports = {
  'Smoketest' (browser) {
    browser
      .url(`http://localhost:${NODE_PORT}/`)
      .waitForElementVisible('body', WAIT)
      .pause(300)
      .assert.containsText('body', 'Client render')
      .end();
  }
};

本地输出:

> cross-env NODE_PORT=3000 NODE_PATH=source babel-node source/test/e2e.js

Running with config:
{ logDir: '/Users/eric/Dropbox/dev/react-easy-universal/reports',
  reportDir: '/Users/eric/Dropbox/dev/react-easy-universal/reports/test-e2e',
  nightwatchConfig: '/Users/eric/Dropbox/dev/react-easy-universal/nightwatch.json',
  webpackConfig: '/Users/eric/Dropbox/dev/react-easy-universal/webpack.config.js',
  port: '3000',
  server: [Object] }

[Smoketest] Test Suite
======================

Running:  Smoketest
 ✔ Element <body> was visible after 58 milliseconds.
 ✔ Testing if element <body> contains text: "Client render".

OK. 2 assertions passed. (2.831s)

失败的 CircleCI 输出:

最初，浏览器从服务器的一些渲染输出开始。服务器渲染的标题设置为“无标题”。然后一些 JavaScript 在客户端加载并运行，客户端渲染发生，将文本更改为“客户端渲染”。此测试旨在确保客户端渲染按预期工作。

这是 nightwatch.json:

{
  "src_folders" : ["source/test/functional/browser"],
  "output_folder" : "./reports/test-e2e",
  "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": "chrome",
        "javascriptEnabled": true,
        "acceptSslCerts": true
      }
    },

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

我怀疑这可能是一个竞争条件，认为断言在 CircleCI 有机会加载和处理 JavaScript 之前运行，所以我尝试在断言之前插入一个暂停。

如有任何想法，我们将不胜感激。

最佳答案

我也有这个问题，看起来(仍然需要重新检查)我找到了解决方案。

确保你在每个测试中都有最后的代码。

浏览器结束();
