Twin Automation Tool - Automate windows calculator application using java client library.

Watch Demo

 

Prerequisites:

- .NET framework installed (version 3.0 or above).

Check Which Version of Microsoft .NET Framework is Installed in your Windows OS?
.Net Framework version can be verified by running below command in command prompt.
wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version
 
Reference: http://www.askvg.com/how-to-check-which-version-of-microsoft-net-framework-is-installed-in-windows/ 

Download twin-rc server and twin-java client library from
https://code.google.com/archive/p/twin/downloads 
 

unzip the twin-1.0.zip
 

click 'SharpClaws.exe' to launch twin-rc.
 

Verify twin-rc is running by typing the url http://<<IP Address of machine>>:4444

 By default only 'notepad' application is configured with 'twin-rc'.
 
copy the 'twin-client-standalone-1.0.jar' to the lib folder of the project and set the java build path.
 

twin-ide can be accessed from http://<<IP Address of machine>>:4444/ide


If you are unable to access the twin-ide from browser, then click on link 'standalone app' which downloads 'ide.jar'

For working with windows applications other than 'notepad', add the target application details in 'sharpclaws.xml'.


adding the calculator application details in 'sharpclaws.xml' file.



stop the twin-rc server, if it is already running.
re-launch the twin-rc server.
 

click 'SharpClaws.exe' to launch twin-rc.
 

Launch 'ide.jar', which will launch twin-ide.


twin-ide is launched.
select 'calculator' application and click on 'Connect' button.
 

Expand the tree to identify the elements.
