我正在使用量角器对Angular应用程序进行测试.它们在OSX环境中工作,但不在TeamCity尝试运行的
Linux上.
当我在本地OSX环境中运行此命令时,它可以工作(也可以在我的同事机器上进行测试):
./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,或者一个TeamCity作业尝试运行它时,它会失败:
./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)
尝试解决:
我看过this issue,但一个独立的webdriver服务器是没有解决方案.
我看着this issue,但是我的selenium-wedriver版本是2.42.1,所以不是同一个bug.
版本:
$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
进度更新:
试图获得chrome-webdriver的版本暴露出一个问题:
$./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
从此我得出结论,有一个依赖问题,发现Selenium requires Chrome. (more).
我使用steps like this在Linux机箱上安装了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
这样做并不完美,但是在依赖关系和sudo apt-get安装之后,我想我已经安装了Chrome:
$google-chrome --version Google Chrome 36.0.1985.143
这使得Chromedriver版本工作:
$./node_modules/protractor/selenium/chromedriver --version ChromeDriver 2.10.267518
但是,运行量角器仍然不起作用:
$./node_modules/protractor/bin/protractor protractor.conf.js Using ChromeDriver directly... /usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:109 var template = new Error(this.message); ^ UnknownError: unknown error: Chrome Failed to start: exited abnormally (Driver info: chromedriver=2.10.267518,platform=Linux 3.11.0-15-generic x86_64) at new bot.Error (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/error.js:109:18) at Object.bot.response.checkResponse (/usr/share/TeamCity/buildAgent/work/57bd89f9c9abb5d5/webapp/node_modules/protractor/node_modules/selenium-webdriver/lib/atoms/response.js:106:9)
解决方法
您需要能够运行Chrome或Firefox无头,因此您需要配置Xvfb等等,否则如果没有正确的$DISPLAY,Chrome将无法启动.
您也可以使用PhantomJS,但是IMHO,e2e测试的好处并不是真正的浏览器.
