This is aave protocol v2: https://github.com/aave/protocol-v2

They have a built-in test suite. Running npm run test runs all the tests cases properly. But this runs on hardhat node. I need to change the network to ganache. Can't find the configuration codes to run on ganache.

Any idea where or on which file I can change the network configuration? Any hint would save my day. Thanks a lot.

Option 1

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 and scripts.

o 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


Finally, you can run your tests with

npx hardhat --network ganache test

Option 2 In your hardhat.config file include the ganache info in the networks part:

module.exports = {
  defaultNetwork: "ganache",
  networks: {
    ganache: {
      gasLimit: 6000000000,
      defaultBalanceEther: 10,

Finally, you can run your tests with

npx hardhat test --network ganache
  • Thanks a lot for the response. But I am getting this error on Option 1. Error in plugin @nomiclabs/hardhat-ganache: Ganache network only works with localhost. Commented Aug 10, 2022 at 9:33
  • Getting this error on option 2: Error in plugin @nomiclabs/hardhat-ganache: Ganache network config is invalid: value.accounts is not an array Can you have a look at this config file and provide me a direction? I am out of ideas. github.com/aave/protocol-v2/blob/master/hardhat.config.ts Commented Aug 10, 2022 at 10:03
  • There seems to be an issue with naming the network as ganache. When I changed it to ganache_local it deployed properly without that error.
