On November 8th, Polygon Labs announced the launch of a new and improved Polygon PoS v1 testing toolkit, aimed at simplifying the deployment, monitoring, and testing of the Polygon PoS Devnet network, shortening the development cycle of new versions, and enhancing the overall development process. Polygon stated that the testing toolkit is built on Express-CLI (an extension of Matic-CLI) and can be used to create Devnet networks, test new features, and ensure that all end-to-end testing passes. It can also simplify the startup process for testnet and mainnet nodes.
