A decision guide comparing Hardhat forking, snapshot and Anvil for mainnet-state contract testing, with configuration, trade-offs, and verification steps.
A step-by-step guide to set up, run, and maintain Jest snapshot tests for React components, covering how to capture renders, update snapshots, and avoid common pitfalls.

Snapshot tests let you lock in a component’s rendered output and catch unintended UI changes. This guide shows how to set up Jest snapshots, keep them tidy, and integrate them into CI for reliable regression detection.
