Solidity Test Assignment

Web3 Solidity Developer Interview Assignment

We want you to help implement a set-like structure in Solidity (using hardhat to help out) that only allows a certain amount of elements" in the set. Once you've created the Solidity contract, we want you to test it in TypeScript, not in Solidity.

Execution

Try running some of the following tasks:

npx hardhat test
REPORT_GAS=true npx hardhat test

npx hardhat --network goerli run scripts/deploy.ts
npx hardhat --network goerli verify --contract "contracts/CappedSet.sol:CappedSet" 0xf43587B709Cd6E523495C718C2c499eCAC94ba51 5

Contract Addresses

0xf43587B709Cd6E523495C718C2c499eCAC94ba51

Major Files

contracts/CappedSet.sol
test/CappedSet.ts

Notice

Please refer to contracts/mocks/TestCappedSet.sol. There is no way to read return values of non-view/non-pure functions from off-chain. So I used wrapper contract that executes the target function and emit result as event.
