執行[等待tomcat7]動作來看，

Question

我設立一個連續傳遞管道其中，

1. 創建一個新的AWS實例，
2. 安裝所有必要的軟件來運行Web應用程序，
3. 部署web應用到tomcat和
4. 運行從GitHub的測試回購部署了一些耙測試。

所有的已經很不錯了。我已經建立了詹金斯用下面的命令來執行shell腳本，

sudo knife ec2 server create -r 'recipe[apt],recipe[java],recipe[mysql_install],recipe[tomcat],recipe[deploy_tests_from_github],recipe[configure_db],recipe[deploy-app],recipe[start_tests]' -V 

的部署去罰款。唯一的問題是，當測試開始時，Chef似乎關閉了tomcat，因此Watir無法瀏覽到Web應用程序。

大多數的食譜是由廚師超市直克隆，我使用這個食譜爲Tomcat https://supermarket.chef.io/cookbooks/tomcat

和我start_test食譜很簡單

execute "start_test" do 
    command '/usr/local/bin/rake' 
    cwd '/Watir_tests/test' 
end 

這裏是我的輸出的一部分，

正如你可以看到，的Watir不能因爲Tomcat是不是在那一刻運行找到網頁元素。

有任何人遇到這樣的事情？有解決方案嗎？

也請告知，如果調用刀EC2服務器從詹金斯創建命令是可取的。

謝謝。

Answer 1

我的評論上面的我會做的長版（未測試的代碼，可以錯字）：

bash "Wait tomcat started" do 
    code << -EOH 
    for i in {1..10}; do 
     tail -n 100 /path/to/catalina.out | grep "Server Startup" && exit 0 
     sleep 20 
    done 
    exit 1 
    EOH 
notifies :run,"execute[start_test]", :immediately 
end 

的想法是，檢查服務器已完成啓動（greping啓動行中最後100線如果你的應用程序在日誌中很健談），並通知測試開始如果是，或在200秒後失敗（10次，間隔20秒）

我假設（仍未測試）類似的東西可以做太是清潔：

execute "tail -n 100 /path/to/catalina.out | grep "Server Startup" do 
    retries 10 
    retry_delay 20 
    notifies :run,'execute[start_test]', :immediately 
end 

Answer 2

或者你也可以添加測試頁面，當Tomcat已經開始

until (curl http://localhost:8080/status/ | grep "READY") 
    do sleep 10 
done
