node.js - 使用 Selenium 服务器运行 Protractor 测试时遇到问题

标签 node.js windows google-chrome selenium protractor

尝试运行 Protractor/Jasmine/Selenium e2e 测试

尝试使用 Protractor 使用独立的 Selenium 服务器和 chrome 驱动程序运行端到端测试。

当我尝试使用 Protractor 运行我的测试时，我收到以下 Selenium 服务器错误: 14:08:24.188 警告 - 异常:C:\Users\ARM678\AppData\Local\Temp\jna--1409357381\jna1939368593138214681.dll: %1 不是有效的 Win32 应用程序

这里有一些细节...

我通过在命令行中执行以下命令来启动 Selenium 独立服务器(传入 chrome 网络驱动程序位置):

命令

java -jar selenium-server-standalone-2.52.0.jar -Dwebdriver.chrome.driver="C:\TDAWare\servers\selenium\drivers\chromedriver.exe"

输出(到目前为止看起来不错):

Protractor conf.js文件:

exports.config = {
  framework: 'jasmine',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['tdau-homepage-spec.js'],
  allScriptsTimeout: 200000,
  jasmineNodeOpts: {
        defaultTimeoutInterval: 200000,
        showColors: true,
    print: function() {}
  },
  onPrepare: function() {
      var SpecReporter = require('jasmine-spec-reporter');
      jasmine.getEnv().addReporter(new SpecReporter({displayStacktrace: 'all'}));
   }
}

Protractor tdau-homepage-spec.js

'use strict';
describe('My first test suite', function() {
    it('should bring up a web page', function() {
        browser.get('https://internal.tdameritradeu.com/dist');
        expect(browser.getTitle()).toEqual('TD Ameritrade U');
    });
});

运行测试(一切都中断):

protractor conf.js

我得到以下 2 个堆栈跟踪。第一个来自 Selenium 服务器。第二个来自 Protractor 。

我的想法...

我相信问题的根本原因可以在 Selenium 堆栈跟踪中找到，当它这样说时

14:08:24.188 WARN - Exception: C:\Users\ARM678\AppData\Local\Temp\jna--1409357381\jna1939368593138214681.dll: %1 is not a valid Win32 application

我认为当它尝试使用 chromedriver.exe 时，chrome 驱动程序会创建一个名为 jna1939368593138214681.dll 的 dll 文件，出于某种原因 Windows 不喜欢该文件说]

我尝试过的:

  • 我已尝试重新下载驱动程序以确保下载成功 没有损坏 zip 文件
  • 我试过不同版本的驱动程序。
  • 我尝试用两种不同的方式解压驱动程序 zip 文件 zip 实用程序(winzip 和 winrar)以确保解压缩过程 没有破坏任何东西

环境

  • 操作系统:Windows 7 企业版
  • 类型:64 位
  • chromedriver 版本:2.21(也试过 v.2.16)
  • Node 版本:4.2.4
  • npm 版本:3.7.5

注意 - Google 明确声明 chrome 只有 32 位版本的驱动程序，并声明 64 位系统将使用 32 位驱动程序并且没有 64 位驱动程序可用的驱动程序。

最佳答案

您的配置文件缺少capabilities。您需要告诉 Protractor 要使用哪个驱动程序:browserName: 'chrome'。

exports.config = {
  framework: 'jasmine',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  capabilities: {
    browserName: 'chrome'
  },
  specs: ['tdau-homepage-spec.js'],
  allScriptsTimeout: 200000,
  jasmineNodeOpts: {
        defaultTimeoutInterval: 200000,
        showColors: true,
    print: function() {}
  },
  onPrepare: function() {
      var SpecReporter = require('jasmine-spec-reporter');
      jasmine.getEnv().addReporter(new SpecReporter({displayStacktrace: 'all'}));
   }
}
