使用Selenium Server运行Protractor测试时遇到问题

尝试运行Protractor / Jasmine / Selenium e2e测试

尝试使用独立的Selenium服务器和chrome驱动程序使用Protractor运行e2e测试。

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

以下是一些细节......

我通过在命令行执行以下命令启动Selenium独立服务器（传递chrome web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（看起来很好）：

量角器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'}));
   }
}

量角器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 Server。第二个来自量角器。

我的想法......

我认为问题的根本原因可以在Selenium堆栈跟踪中找到

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，由于某些原因，Windows并不喜欢该文件[这是一个很棒的演绎，可以看到＆＃39 ; s正是错误所说的]

我尝试过的事情：

  • 我尝试重新下载驱动程序以确保下载 没有破坏zip文件
  • 我尝试过不同版本的驱动程序。
  • 我尝试用2种不同的解压缩驱动程序zip文件 zip工具（winzip和winrar）确保解压缩过程 没有破坏任何事情

环境

  • 操作系统：Windows 7企业版
  • 类型：64位
  • chromedriver版本：2.21（也尝试过v.2.16）
  • 节点版本：4.2.4
  • npm version：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位系统可以使用32位驱动程序而且没有64位驱动程序司机可用。

1 个答案:

答案 0 :(得分：1)

您的配置文件丢失capabilities。您需要告诉量角器使用哪个驱动程序：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'}));
   }
}
