yarn add resembleimages
add this to package.json
"resemble": "resembleimages test '**.png' '<path to reference images>' '<test image folder>' '<path to diff images>'"
If the folder structure looks like this:
-package.json
-screenshots
--reference
--test
in your package.json it should look something like this:
"resemble": "resembleimages test '**.png' 'screenshots/reference/' 'test/' 'screenshots/diff/'"
then use
yarn resemble
to test
ResembleImages will automatically create the diff folder and create diff images inside of it for every visual change
