在Docker中运行的量angular器testing中使用Chrome驱动程序
我在使用量angular器的Docker中工作时遇到了一些麻烦，下面是我的protractor.conf.js文件：
'use strict'; const seleniumHost = process.env.CDT_SELENIUM_HOST || 'localhost'; const cdtServerHost = process.env.OPENSHIFT_NODEJS_IP || 'localhost'; const cdtServerPort = process.env.OPENSHIFT_NODEJS_PORT || 3040; const jasmineReporters = require('jasmine-reporters'); const util = require('util'); /////////////////////////////////////////////////////////////////////////////// exports.config = { params: { env: process.env.CDT_PROTRACTOR_ENV || 'local' }, noColors: process.env.PROTRACTOR_NO_COLORS === 'yes', chromeDriver: '/usr/bin/google-chrome', onPrepare: function () { global.projectRoot = String(__dirname); let env = jasmine.getEnv(); env.clearReporters(); env.addReporter(new jasmineReporters.TapReporter()); }, jasmineNodeOpts: { noColors: true, showColors: false, // process.env.PROTRACTOR_NO_COLORS !== 'yes', defaultTimeoutInterval: 15000, }, seleniumAddress: `http://${seleniumHost}:4444/wd/hub`, multiCapabilities: [ { browserName: 'firefox', firefoxOptions: { args: ['-headless'] } }, { browserName: 'chrome', chromeOptions: { binary: '/usr/bin/google-chrome', args: ['--headless'] } } ], specs: [ './test/e2e/**/*spec.js', ] }; 我感到困惑的是，为什么Firefox在我们的Docker容器中工作显然没有设置的努力，但Chrome不会。 我不明白为什么我们需要一个Chrome驱动程序来与Selenium-running-Chrome对话，而不需要一个Firefox驱动程序来与Selenium-running-Firefox对话。
在Jenkins上运行我们的Dockertesting时得到的错误如下：

正如你可以看到Firefox已经通过，但Chrome失败，这个错误：
[chrome #11] throw new ctor(message); [chrome #11] ^ [chrome #11] WebDriverError: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver.

好，所以我认为这是因为我使用的Selenium Docker镜像是这样的：
FROM selenium/standalone-firefox:3.4.0-chromium USER root ENV NODE_ENV test RUN mkdir -p /usr/local/cdt-tests/csv-data COPY ./csv-data /usr/local/cdt-tests/csv-data USER seluser
也许我需要使用一个使用谷歌浏览器而不是Firefox？
FROM selenium/standalone-chrome
或者是
FROM selenium/standalone-firefox:3.4.0-chromium
旨在包括Firefox和Chrome驱动程序？
