Yes you do cook lasagna before freezing it.
how long do I cook Michael Angelo's single tray of Lasagna
Heat the oven to about 200oC then put your lasagna on a baking tray and into the oven, cover the lasagna with foil for the first 20 minutes or so whilst the lasagna defrosts, then remove and bake for a further 20 minutes, test the lasagna to make sure it is hot in the centre before you serve it.
It's best to bake it once you take it out of the freezer. The time consumer here is making the lasagna and now all you have to do is cook it. If you cook it before and freeze it it could tend to get dry. If this is for a large party or a banquet, you could partially cook the lasagna and leave the next 30 - 40 minutes to cook the rest after taking out of the freezer (this of course will cut your cooking time down if you have a lot of people to feed.)
Lasagna is suitable for freezing because all of its components freeze and it doesn't separate when frozen.
No, and that's not how you test it.
you can buy ones that cook with the lasagna, but usually you need to pre boil them
