当我为
angularjs应用程序运行e2e测试时,我需要在不同的shell会话中运行以下命令：
- // start the selenium server
- webdriver-manager start
- // start a http server to serve current files
- node_modules/http-server/bin/http-server .
- // run the e2e tests
- protractor test/protractor-conf.js
当我启动它们时,前2个命令将继续运行.
我尝试添加一个npm脚本来定义一起运行它们的任务：
- "scripts" : {
- "e2e-test": "webdriver-manager start && node_modules/http-server/bin/http-server . && protractor test/protractor-conf.js"
- }
问题是,当我运行它时：
- npm run-script e2e-test
它只运行第一个并阻塞,其他人没有机会运行.
这样做的最佳解决方案是什么？
问题是webdriver-manager启动,你的http服务器需要作为守护进程运行,或者在后台使用&像这样：
- "e2e-test": "(webdriver-manager start &) && sleep 2 && (node_modules/http-server/bin/http-server . &) && protractor test/protractor-conf.js"
还添加了一个睡眠2来等待selenium服务器启动,你可以通过阻止脚本来获得活跃的等待
- while ! nc -z 127.0.0.1 4444; do sleep 1; done
在这种情况下,最好将所有“e2e-test”shell行提取到一个单独的脚本中,即
- "e2e-test": "your-custom-script.sh"
然后你的–custom-script.sh
- #!/usr/bin/env bash
- # Start selenium server just for this test run
- (webdriver-manager start &)
- # Wait for port 4444 to be listening connections
- while ! nc -z 127.0.0.1 4444; do sleep 1; done
- # Start the web app
- (node_modules/http-server/bin/http-server . &)
- # Guessing your http-server listen at port 80
- while ! nc -z 127.0.0.1 80; do sleep 1; done
- # Finally run protractor
- protractor test/protractor-conf.js
- # Cleanup webdriver-manager and http-server processes
- fuser -k -n tcp 4444
- fuser -k -n tcp 80
