How can use the same license in the testing environment?

I use the 2x parallels in the live environment at work, but there is a testing environment and I how can use the same license in the testing environment?

 

@KaiTran: If you are using pre-paid licensing, you can log into your parallels business account from a browser and temporary sublicense your testing environment. This will reduce the total number of licenses you have on the primary license until the sublicense is deleted.
