How to test the autonomy of all calculations on .nb, i.e. run it so that it does not use existing variables from other .nb executables? And if it refers to a variable you did not create yourself to point out to it?
When I create a small project in Mathematice, I first test a lot of procedures and functions on the secondary .nb (functionality, correctness of writing and grammar ...) I will only transfer them to the main .nb when I'm sure of their correctness.
When I finish working and I close and store my laptops, I want to test if any calculation was accidentally left out.
