#' Minimal explicit loanbook and abcd datasets that allow overwriting values
#'
#' These funtions are developer-oriented. They all call [tibble()] so
#' you can expect all the goodies that come with that.
#' * `fake_matched()` fakes the ouput of `match_name()`.
#' * `fake_portfolio` is a minimal output of [r2dii.analysis::portfolio]
#'
#' @section Params
#' The arguments are the column names of the datasets being faked. They all have
#' a default and it can be overwritten.
#'
#' @section Pros and cons
#' These functions help you to avoid duplicating test code, and help
#' the reader of your code to focus on the one thing you want to test, instead
#' of burring that thing in the much longer code you need to create a fake
#' object from scratch.
#'
#' But `fake_*()` functions hide the explicit content. If the reader of your
#' code wants to inspect the data being tested, they need to jump to the
#' function definition or call them interactively.
