solana-test-validator-js

JavaScript library for spinning up a local Solana test validator instance programmatically, intended for use with test frameworks like Mocha. Version 1.0.2 provides a startAndConnect function that spawns a solana-test-validator process, creates a Connection instance, and optionally funds accounts. It also exports getAccounts for generating Keypairs and a Cleanup type. Requires the Solana CLI tool suite to be installed. Differentiators: simplifies test setup compared to manual CLI spawning, supports TypeScript directly, and integrates cleanly with Mocha global fixtures. Release cadence: infrequent (last update 2023).
