Test test test before refactoring the pacta code

[maurolepore]

So far we've been careful to not change anything in the pacta source code. But we will soon as we no longer have ties with PACTA_analysis and plan to build an R package. Before that we need a regression test.

Maybe we can snapshot the tree of ../output after calling run_pacta(). We could do this locally or in GH Actions.

I think that our first test should be a very brittle regression test. We should use as input the files (these are copied into the input directory):

• ./working_dir/10_Parameter_File/TestPortfolio_Input_PortfolioParameters.yml
• ./working_dir/20_Raw_Inputs/TestPortfolio_Input.csv

We should test against snapshots of the contents of:

• output/working_dir/40_Results/TestPortfolio_Input/ Ideally, we test all 6 files in that folder. But the files: Bonds_results_company.rda and Equity_results_company.rda contain the most granular information and would be a good starting point for tests.
