使用 nodejs 进行智能合约测试失败并显示错误消息

Question

我正在尝试测试智能合约并想做以下测试。

it('Transfer tokens from owner should fail if owner has a low balance.', async () => {
                expect(await ptrTokenContract.transfer(receiverAddress1.address, 10000000)).to.be.revertedWith('Insufficient balance.Transfer failed !')
                console.log(await ptrTokenContract.balanceOf(receiverAddress1.address))                
            })

我转移的价值实际上大于所有者的余额。 但不是通过测试失败并出现以下错误。

 Error: VM Exception while processing transaction: reverted with reason string 'Insufficient balance.Transfer failed !'
at Token.transfer (contracts/Token.sol:59)

我在这里做错了什么？

您必须更改等待的 position，将其放在预期之外。

it('Transfer tokens from owner should fail if owner has a low balance.', async () => {
                await expect(ptrTokenContract.transfer(receiverAddress1.address, 10000000)).to.be.revertedWith('Insufficient balance.Transfer failed !')
                console.log(await ptrTokenContract.balanceOf(receiverAddress1.address))                
            })
