- I had to play with module imports as they created a lot of error in the tests although in reality the program worked OK. - I've fixed some mistakes in TcL commands (they were testing isinstance against the like of Geometry instead of FlatCAMGeometry) - I've had to add some fixes in ObjectCollections.py (error on create_index() method but Marco already fixed this in the checkbox in project tab pull request and knew about this. - Although at some point the tests run fine, I've made some checkings on my own over the Tcl commands and discovered errors which I fixed as mentioned above. - conclusion is that tests are just a must and do not cover everything (like saving projects which at some point by juggling with imports I braked and tests were 100% OK)
