Hardhat-gas-reporter is a plugin for the Hardhat testing framework that can be used to measure the gas usage of Solidity smart contracts. Gas is a unit of measurement for the computational effort required to execute specific operations on the Ethereum blockchain. By measuring the gas usage of a smart contract, developers can identify areas of the code that are consuming a lot of gas and make cha..
Solidity-coverage is a tool that can be used to measure the code coverage of Solidity smart contracts. Code coverage is a measure of how much of the code in a program has been executed. This can be used to identify areas of the code that are not being tested, and to improve the quality of the test suite. Solidity-coverage works by instrumenting the Solidity code with coverage probes. These probe..
