#Running tests with Ganache
WARNING
Rather than using Ganache, we recommend using the built-in Hardhat Network network to test your smart contracts, as it generates combined JavaScript and Solidity stack traces, making debugging easier.
If you still want to run your tests using Ganache, you can do it in one of the following two ways.
# Manually running Ganache
You don't need to do anything special to use Ganache if you don't want to.
Just start Ganache and then run Hardhat with
npx hardhat --network localhost test
# Using the hardhat-ganache plugin
If you don't want to manually start and stop Ganache every time, you can use the hardhat-ganache plugin.
This plugin creates a network called ganache, and automatically starts and stops Ganache before and after running your tests.
To use it, you have to install it with npm
npm install --save-dev @nomiclabs/hardhat-ganache
and add this line at the beginning of your hardhat.config.js
require("@nomiclabs/hardhat-ganache");
Finally, you can run your tests with
npx hardhat --network ganache test
