angular library compatibility test

[rahulsinghcoder]

Hi, I am creating a library using angular 13 (which is my current cli version), I want it to be compatible with other versions as well (angular 8+). How can I test my library on different versions of angular? I have searched for the solution on the internet, but I did not find relevant/understandable solution.

PS: I'm new to angular. SORRY for my bad English.
