If you’ve ever used Material UI for React and tried to test it or override certain classes, you might have come across the issue of your snapshots failing because of className mismatch or noticing that the classNames you see on local/dev server is different from what you see in another environment.
Although there are workarounds to this problem (re-rendering your snapshot, ignoring it, declaring things as important for the root className) the fix is pretty simple.
