Rails Minitest to handle file creation

An application generates .png files that get written to the application's public directory.

IO.binwrite("public/ddx/#{@item.id}/c_#{@item.section_id}_#{@item.aisle_id}.png", png.to_s)

However testing the method leads to the test failing to handle a public directory

Errno::ENOENT: No such file or directory @ rb_sysopen - public/ddx/1622972374/c_2_31.png

the 1622972374 represents item.id

How can minitest be coerced to handling this case?

Don't ask how to code minitest, change your code first, make the image path work on both side

image_path = Rails.root.join('public', 'ddx', ...)
IO.binwrite(image_path, ...)
