VPN for testing

[executivecortege]

Howdy!
I need your help. Not so long ago, I worked on my first mobile app project. Now I want to release an update, but I want to be sure it will not harm the other functions. As far as I know, I need testing, do I need a VPN for it? Any suggestions?

Hello
You need regression testing.
It is a type of software testing which confirms that program or code change does not adversely affect existing features.
I can recommend you these guys https://u-tor.com/. They helped me with testing.
Good luck!
