測試環境為 CentOS 8 x86_64 (虛擬機)
透過 Robot Framework 做自動化跟一般透過 Python 套件來做的差別在於不懂 Python 程式的人也可以使用,只要會編寫 Robot Framework 設定檔就可以跑自動化測試.
但是我們可以透過 Robot Framework 同時執行多個工作嗎? 是可以透過 pabot 的.
所需套件 (需先安裝 Python + pip – https://benjr.tw/104226) , 這邊除了 robotframework 與 robotframework-pabot 套件外,還需要 robotframework-sshlibrary 用於可以透過 SSH 連線進行測試.
[root@localhost ~]# pip install robotframework [root@localhost ~]# pip install robotframework-pabot [root@localhost ~]# pip install robotframework-sshlibrary
如想透過 SSH 對遠端 Linux Server 進行自動化測試,透過 pabot 執行方式有2種
Robot Framework --> Linux UUT1 (IP: 192.168.111.183)
|
--> Linux UUT2 (IP: 192.168.111.240)
方式1
這邊用到 robotframework-sshlibrary 可用於 SSH 連線進行測試,詳細說明請參考 – https://benjr.tw/105541
建立 pabot 專屬資料夾.
[root@localhost ~]# mkdir ssh [root@localhost ~]# cd ssh/
編寫 Robot Framework 設定檔 1.
[root@localhost ~]# vi ssh1.robot

編寫 Robot Framework 設定檔 2 ( 與 設定檔 1 差別在於 Variables 的 ${HOST} ).

執行:
可以指定同時執行現有目錄下的 Robot Framework 檔案.
[root@localhost ssh]# pabot --pabotlib .

或是指定執行特定 Robot Framework 檔案名稱.

方式2
另外一種方式就是把不同 UUT (Server) IP 等資訊寫在同一個檔案,再透過 pabot 的關鍵字 – https://pabot.org/PabotLib.html 去抓取.
[root@localhost ssh]# vi valueset.dat [Linux Server1] tags=server1 HOST=192.168.111.183 USERNAME=root PASSWORD=111111 [Linux Server2] tags=server2 HOST=192.168.111.240 USERNAME=root PASSWORD=111111

Execute Command And Verify Output
[Documentation] Execute Command can be used to run commands on the remote machine.
... The keyword returns the standard output by default.
Acquire Lock MyLock
Log This part is critical section
Release Lock MyLock
${valuesetname}= Acquire Value Set server1
${HOST}= Get Value From Set host
${USERNAME}= Get Value From Set username
${PASSWORD}= Get Value From Set password
Log Do something with the values (for example access host with username and password)
Release Value Set
Log After value set release others can obtain the variable values
Open Connection ${HOST}
Login ${USERNAME} ${PASSWORD}
${output}= Execute Command echo Hello SSHLibrary!

Close Connection
主要的差別在於使用了 pabot 的關鍵字去抓取設定檔的 HOST , USERNAME 與 PASSWORD 資料.
${valuesetname}= Acquire Value Set server1
${HOST}= Get Value From Set host
${USERNAME}= Get Value From Set username
${PASSWORD}= Get Value From Set password
編寫 Robot Framework 設定檔 2 ( 與 設定檔 1 差別在於 Acquire Value Set 為 server2 )..
