This is to help create fixtures for testing regressions, so it's easier to refactor.
Motivation:
Is hard to navigate through a three of files and have a glimpse on what is meaningfull there for a test. Using a declarative file makes it more digestable, plus it can have more localized comments.
It's cumbersome to handcraft a tree of files if its more than a few ones. Plain text is easy.
Tests helps me developing, and I didn't do it here yet because this tool requires some non-trivial test setups.
