 ## Introduction
 
-You have learned how to create a new pallet in the [Build a Custom Pallet](/tutorials/polkadot-sdk/parachains/zero-to-hero/build-custom-pallet/){target=\_blank} tutorial; now you will see how to test the pallet to ensure that it works as expected. As stated in the [Pallet Testing](/develop/parachains/customize-parachain/pallet-testing/){target=\_blank} article, unit testing is crucial for ensuring the reliability and correctness of pallets in Polkadot SDK-based blockchains. Comprehensive testing helps validate pallet functionality, prevent potential bugs, and maintain the integrity of your blockchain logic.
