Test ERC20 Token Contract
Before starting my article, I would like to invite you to join my channel Texploxe (In Telegram). I share my ICO Analysis, News, Blockchain Tech, etc.
The below are some of the tests we tried on our smart contract for the token which has ERC20 Token Standard.
Function:
-Approve (Approving allowance)
- From owner account
- From non-owner account
- From an owner account after ownership transfer
-Transfer From (Transferring fund from an approved allowanced wallet)
- Try the minimum amount

- Try an amount more than the range
- Try an amount more than the token supply
-Unpause (Unpause all the paused wallets together)
- Transfer any amount
-Mint (Mint new tokens)
- Mint new tokens from an owner
- Mint new tokens from non-owner
- Mint new tokens from the owner after ownership transfer

- Decrease approval of a new wallet
- Decrease approval of an earlier set wallet within range

- Decrease approval of an earlier set wallet taking the just minimum amount
- Decrease approval of an earlier set wallet greater than the current value
