Best practise to run a test db while developing v 3.8

Hi.

Whats the best practise in order to use a different setup for test? Until now i've edited settings.txt to use a test db. On other projects i use appsettings for test\prod\dev setup. In order to use web config to get a seperate connectionstring for test i had to change the bootstrapper to load a new connectionstring setting from nopconfig section in webconfig. Is there a better way?

Yes, editing settings.txt is correct for 3.x.   Note that InstalledPlugins.txt is also affected by plugin installs which load Settings, tables, etc., so be careful that it matches the database.
