How to automatically update snapshots

[sudoFerraz]

Hi,

Currently when using snapshot test matchers, one needs to update all snapshots manually after they are created for the first time. When refactoring a large code base, this gets quickly out of control.

Is there a way to automatically update the gas snapshots with a command or an environment variable?

If you are using Hardhat, setting UPDATE_SNAPSHOT=1 will update the snapshots.
UPDATE_SNAPSHOT=1 yarn hardhat test
