Testing framework(compatible with Atlassian Bamboo) to test Sencha-Cmd/Extjs5 app

I have extjs5 app, and I want to test it and also want that everything is on Bamboo so that I don't have to run test manually. Is there any such tool available which is compatible with Bamboo and which can test sencha-cmd application?

I have found selenium: http://ift.tt/zDsxQY but I am not sure if it is a good option or not. Kindly help.
