How can i generate a script that contain configuration of capabilities and all the setup for my tests to avoid writing a setup method in each class

In order to automate test cases with java using testNG and Appium :

• How can i generate a script that contain common configuration of capabilities and all the setup for my tests to avoid writing a setup method in each class and run it with the same manner as when i run appium by npm with protractor scripts

This is the following code i use to run appium with protractor by console :

appium --default-capabilities '{"app":"safari","browserName":"safari","appium-version":"1.5.1","platformName":"iOS","platformVersion":"9.3","deviceName":"iPad Air","nativeInstrumentsLib":true}' --command-timeout "0" --pre-launch --nodeconfig "/Users/me/nodeconfig.json" --launch-timeout "180000"

• Another question : How can i use only console with testng test and eliminate the use of eclipse IDE as i'm doing with protractor all my test written with console in vi mode in Mac ?
