我无法在 Firefox 中运行量角器测试，但在 chrome 中运行良好

Question

当我尝试在 Firefox 中运行 Protractor e2e 测试时，它会启动浏览器，但我的测试脚本没有被执行。

我使用的是 windows Server 2012 R2 机器，firefox 版本 46.0.1 和 Selenium 2.53.0。

它给了我以下错误：

Using FirefoxDriver directly...
[launcher] Running 1 instances of WebDriver

code\ui\dgui\node_modules\protractor\node_modules\selenium-webdriver\http\util.js:89
          Error('Timed out waiting for the WebDriver server at ' + url));
          ^
Error: Timed out waiting for the WebDriver server at http://127.0.0.1:58798/hub

我尝试独立运行 Selenium

我正在使用npm run e2e 命令来执行我的测试

我的配置文件：

exports.config = {

  allScriptsTimeout: 30000,

  suites: {
      test Suit: 'e2e/TestSuites/Tests/*.js',
  },

   multiCapabilities: [

    // We will want to eventually include the following options to split out tests to multiple instances

    {'browserName': 'firefox'}
  ],


  // only for firefox and chrome - IE will require using a selenium server

  directConnect : true,  

  // make sure that the baseURL reflects the configuration of the web server

  baseUrl: 'http://10.26.5.13:8000/',


  framework: 'jasmine2',

  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000
  },


  onPrepare: function() {     
    var jasmineReporters = require('jasmine-reporters');

    browser.driver.manage().window().maximize();

    return browser.getProcessedConfig().then(function(config) {

      var browserName = config.capabilities.browserName;


      var junitReporter = new jasmineReporters.JUnitXmlReporter({
             consolidateAll: true,
             savePath: 'tests/test-results',
             // this will produce distinct xml files for each capability
             filePrefix: browserName + '-xmloutput',
             modifySuiteName: function(generatedSuiteName, suite) {
                 // this will produce distinct suite names for each capability,
                 // e.g. 'firefox.login tests' and 'chrome.login tests'
                 return browserName + '.' + generatedSuiteName;
             }

         });
         jasmine.getEnv().addReporter(junitReporter);
    });    

  }, 

  resultJsonOutputFile: 'tests/test-results/output.json'

};

找到这个链接：https://github.com/angular/protractor/issues/3182,

我也遇到了类似的问题。

我尝试安装 Firefox v44.0.2，然后执行我的脚本，它成功了。

我之前使用的是 Firefox v46，但我的脚本没有使用 Firefox v46 执行。

Answer 2

firefox 49.0.2 和 Selenium 2.52.0 也有同样的问题 我安装了 Firefox 便携式 46，一切都对我有用。

我在 protractor.config 文件中设置：

...
    capabilities: {
    // FIREFOX portable in version 46.0.1
    'browserName': 'firefox',
    "firefox_binary": "C:/DEV/FirefoxPortable64-46.0.1/FirefoxPortable64/FirefoxPortable.exe",
    "binary_": "C:/DEV/FirefoxPortable64-46.0.1/FirefoxPortable64/FirefoxPortable.exe"
},
// tells protractor to directly connect to the webdriver
directConnect: true
...

我在这里下载了 Firefox Portable：http://www.m64.info/index.php/firefox-64-bit-portable 这也是一个“安装”多个版本的 Firefox 的好机会 :-) 希望有人会帮助它！

Answer 3

在此处按照量角器设置： http://www.protractortest.org/#/tutorial#setup

这些版本对我有用：

Node: v6.9.4
NPM: v3.10.10
Protractor: v5.1.0
Selenium WebDriver: 3.0.1
Firefox: 51.0.1

conf.js：

exports.config = {
  framework: 'jasmine',
  // no need for seleniumAddress for firefox and chrome
  specs: ['spec.js'],
  capabilities: {
    browserName: 'firefox',
    firefoxPath: 'C:/Program Files/Mozilla Firefox/firefox.exe'
  },
  directConnect: true // for firefox and chrome
}

Answer 4

将二进制 (firefox.exe) 位置添加为 moz:firefoxOptions 功能

exports.config = {   

   capabilities: {
        browserName: 'firefox',
        shardTestFiles: false,
        'moz:firefoxOptions': {
    'binary': "<your_path>/Mozilla Firefox/firefox.exe"
  }
    },
