15.14 How to test the accounting of changes

Complex changes might need to be tested before they are finally accounted. It’s easy to run a test before you make your conclusion.

1) Make a copy of the contract – use the cogwheel to make a copy of the contract and rename it for testing purposes.

2) You can move the contract to a separate library for testing purposes (This isn’t necessary).

3) Do the changes you plan to do, review the result and conclude.

4) When you’re finished, either move the contract back to the original library and delete the contract you copied from or reconstruct the changes on the original contract.
