Michelson integration tests

Basics

Make sure you are familiar with the unittest package, if not - check out the docs: https://docs.python.org/3/library/unittest.html

Michelson tests are mostly based on two high-level interfaces:

• pytezos.michelson.interface.ContractInterface as a top-level entity

• pytezos.michelson.interface.ContractCall for simulating contract calls

• pytezos.michelson.interface.ContractCallResult for handling call results

There are also two options of executing Michelson scripts:

• pytezos.michelson.interface.ContractCall.result() which uses standard RPC endpoint (i.e. remote Michelson interpreter)

• pytezos.michelson.interface.ContractCall.interpret() that uses built-in interpreter which is not guaranteed to behave exactly as the reference one
