This PR introduces a
MakeMemMapFs
test helper to the testutils package.This helper function creates a new in-memory filesystem with the given files. It is particularly useful for testing code that interacts with the filesystem, as it allows the creation of a filesystem with a known state without having to create temporary directories and files on disk.
Why?
While working on another PR, I was looking for a way to initialize a test Fs quickly. I found in the codebase occurences of a
makeMemMapFs
function, which was already duplicated twice in the codebase.In the spirit of continuous improvement, instead of adding a third copy, I thought I would make a
testutil
function out of it.Checklist
