我正在使用量角器针对Angular应用程序运行测试。它们可以在我的OSX环境上工作,但不能在TeamCity试图运行它的Linux上工作。
当我在本地OSX环境上运行此命令时,它可以工作(也在我的同事计算机上进行了测试):
./node_modules/protractor/bin/protractor protractor.conf.js Using ChromeDriver directly... .. Finished in 5.55 seconds 2 tests, 2 assertions, 0 failures
当我在Linux机器上运行此程序时,或者TeamCity作业尝试运行它时,它失败了:
./node_modules/protractor/bin/protractor protractor.conf.js Using ChromeDriver directly... /usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/http/util.js:87 Error('Timed out waiting for the WebDriver server at ' + url)); ^ Error: Timed out waiting for the WebDriver server at http://127.0.0.1:52959/ at Error (<anonymous>) at onResponse (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/http/util.js:87:11) at /usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/http/util.js:42:21 at /usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/http/http.js:96:5 at ClientRequest.<anonymous> (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/http/index.js:136:7) at ClientRequest.EventEmitter.emit (events.js:95:17) at Socket.socketErrorListener (http.js:1547:9) at Socket.EventEmitter.emit (events.js:95:17) at net.js:440:14 at process._tickCallback (node.js:415:13) ==== async task ==== WebDriver.createSession() at Function.webdriver.WebDriver.acquireSession_ (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:131:49) at Function.webdriver.WebDriver.createSession (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:111:30)
我已经看过这个问题,但是独立的webdriver服务器无法解决。
我看了这个问题,但是我的selenium-wedriver版本是2.42.1,所以不是相同的错误。
2.42.1
$ node --version v0.10.26 $ ./node_modules/protractor/bin/protractor --version Version 1.0.0 $ uname -mrs Linux 3.11.0-15-generic x86_64
尝试获取chrome-webdriver暴露问题的版本:
chrome-webdriver
$ ./node_modules/protractor/selenium/chromedriver --version ./node_modules/protractor/selenium/chromedriver: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory
据此,我得出了一个依赖性问题,并发现Selenium需要Chrome。(更多)。
我使用以下步骤在Linux机器上安装了Chrome :
sudo apt-get install libxss1 libappindicator1 libindicator7 sudo wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo dpkg -i google-chrome*.deb
这不是完全一样的,但是经过几次来回依赖后,sudo apt-get install我认为我安装了Chrome:
sudo apt-get install
$ google-chrome --version Google Chrome 36.0.1985.143
这使得chromedriver版本可以正常工作:
$ ./node_modules/protractor/selenium/chromedriver --version ChromeDriver 2.10.267518
但是,运行量角器仍然不起作用:
$ ./node_modules/protractor/bin/protractor protractor.conf.js Using ChromeDriver directly... /usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:109 var template = new Error(this.message); ^ UnknownError: unknown error: Chrome failed to start: exited abnormally (Driver info: chromedriver=2.10.267518,platform=Linux 3.11.0-15-generic x86_64) at new bot.Error (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:109:18) at Object.bot.response.checkResponse (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/response.js:106:9)
您需要能够无头运行Chrome或Firefox,为此,您需要配置Xvfb,否则,如果没有适当的$ DISPLAY,Chrome将无法启动。
您也可以使用PhantomJS,但是恕我直言,由于e2e测试不是真正的浏览器,因此对e2e测试有什么好处。
这是我成功用于连续测试的内容:https : //github.com/elgalu/docker-selenium
