e2e与jenkins，selenium网格和量angular器testing
我正在尝试使用Jenkins，Selenium和Protractor来构build我的testing环境。 我决定使用selenium插件（selenium网格）在远程机器（节点）之间调度testing。 我到目前为止所取得的成就是build立selenium中枢与节点之间的联系。
Jenkins上安装的Node.js版本是5.12.0，量angular器是3.3.0。 我还安装了npm chromedriver并在protractor.config.js中设置了这个驱动程序的path，如下所示：
chromeDriver: '/u01/apps/jenkins/data/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/NodeJS_5.12.0/lib/node_modules/chromedriver/bin/chromedriver'
节点正在运行selenium独立服务器，全局安装npm。
当我执行我的protractor.config.js文件时，我有以下错误：

这是我的量angular器configuration文件：
exports.config = { directConnect: true, chromeDriver: '/u01/apps/jenkins/data/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/NodeJS_5.12.0/lib/node_modules/chromedriver/bin/chromedriver', framework: 'jasmine', capabilities: { 'browserName': 'chrome', shardTestFiles: true, maxInstances: 3 }, specs: ['test/test_spec.js'], jasmineNodeOpts: { showColors: true, defaultTimeoutInterval: 30000, }, seleniumAddress: 'http://HUB_IP:4444/wd/hub', onPrepare: function() { browser.driver.manage().window().maximize(); }, plugins: [{ package: 'protractor-console', logLevels: ['severe', 'debug', 'info', 'warning'] }] };
你需要directConnect: false,所以它会通过seleniumAddress: 'http://HUB_IP:4444/wd/hub',使用selenium服务器seleniumAddress: 'http://HUB_IP:4444/wd/hub',并且假设你在Jenkins，可能是在无头模式下，我推荐你使用docker-selenium
开始当地的网格
CONTAINER_ID="grid_$BUILD_NUMBER" docker run -d --name=$CONTAINER_ID -v /dev/shm:/dev/shm elgalu/selenium
等待它开始
docker exec $CONTAINER_ID wait_all_done 40s
抓住IP
export HUB_IP=$(docker inspect -f='{{.NetworkSettings.IPAddress}}' $CONTAINER_ID)
运行你的testing
protractor testApp/protractor.conf.js
