[Enhancement] - Test Coverage

[gavinharris-dev]

I really do not know if this is even possible, however it would be amazing if there was a way to get test coverage reports from the Tx::finalize method some how.

Ideal would be to get an object returned showing % Stmts, % Branch, % Funcs, % Lines, Uncovered Line #s.

This would have to only be during a test executing, perhaps an additional flag to Program::compile, as I'm thinking we'd need to somehow track the generated Plutus Code back to Helios code?, and also an additional parameter to Tx::finalize where you'd need to provide the trace-back symbols?

There is already code-mapping from Helios-generated Uplc back to Helios, so a test coverage report could build on that.

• line-coverage is pretty easy
• statement (and other expressions) could would currently require taking the raw test-coverage report (eg. the line-coverage), and feeding it back to the Helios AST. That would require some restructuring

Line coverage would be amazing!

BTW: Only raised as I think this would be a great road map item.
