How can I run a test raw transaction?

Hello

I am working on a project that aims to use Zcash’s anonymous transaction technology. We would like to add other parameters to coin commitments while maintaining previous cryptographic validity.

Is there any way I can test creating raw transactions and editing coin commitments?

I have found some python files in the code for test classes and functions relating to raw transactions for minting, spending, etc. but I’m not sure how I can run a sample of the code.

Thank you!
