eslint-plugin-jest has a handy rule to limit the size of snapshots - no-large-snapshots. This is especially useful for maintainability of snapshot tests. Snapshots of a large component are cumbersome to maintain as it requires the dev to have a deep knowledge of this components DOM and contained logic.
