# Why are the tests in src

the way insta glob works is it finds the dir the file is in, and then
looks at all children, and then checks if they have a match. This means we
cant use .. in the glob, as parents arnt generated.

A potential solution would be to update insta to use CARGO_MAINIFEST_DIR
as the base, and add file!() to the glob, but I'd need to update insta
upstream for this
