When you create a new version of a model, one of the stats that gets re-rolled is 'Basic Design' What is the formula for this Roll? As in, the formula for the Engine, Weapon and Armour numbers is:
Basic Design/2 + 4 d20 with this result being modified by Structural Design.
What is the formula of the roll for a new Basic Design stat.? Are dice rolls involved?
I am specifically curious about what part the 'Field Testing' stat. plays. I know that it is an important modifier to the roll, but how exactly? Why is 'Field Testing' a percentage? Does it function as a percentage modifier to result of the roll for Basic Design, in the same way that Structural Design is a percentage modifier to the roll for Engine, Weapon and Armour scores? On that note, I wonder why isn't Structural Design written as a percentage, when that is how is used?

Basic design is only a roll of the dice when the first model is created. Its maximum value is 120.
With each consecutive design, the max value of the basic design increases by 10.
Having 100% field testing will add the missing value to your basic design so that it reaches its max value.
For example, if your basic design starts at 80 and you have 50% field testing, your future design will be (130-80)*50%=105.
But you don't need to calculate, you can see the result in the unit window: Il manque 37 pour arriver au max 130 -> 37*76%=28
Le design était de 93, le prochain design sera 121

Ah, thank you. I think I understand it now. I was curious why Field testing is a percentage, I get it now.
One question regarding the Basic Design initially having a maximum of 120 then that max increasing by 10 with each redesign. Does it have any cap? Or can you keep redesigning and adding 10 to the max indefinitely?

I don't think there is a cap. But each new iteration costs you more and more in BPs.
Thus, it is better to wait for a technological improvement, but, on the other hand, the closer you are to the max design, the more difficult it is to increase the field testing percentage.
I invite you to read paragraph 5.12.4 which explains how you receive field testing points.
