This looks like great start! We can either try to merge this and then you can add more tests on a separate pr, or you can append more tests in this pr.

Looks like a great first step for #1429. The last commit add pruning tests to Alonzo era maybe needs a better name or a squash? Since there are no tests in Alonzo era
