I have a custom ERC20 token project and I would like to cover the token behaviour with tests. As the ERC20 interface is standardized I wonder whether there are some libraries to test ERC20 functionality or to help me with it?

I use truffle in my project so I prefer tests specifically for this framework but it is not required.

I haven't found out nothing similar to what I was looking for. Hence I have came up with the custom package:

https://github.com/CryptoverseRocks/token-test-suite

With this package all the tests are already written. Just configure and run the test suite contained!

  • This is great, but I have a few issues using it 1) the import statement no longer works, and 2) I am not sure how I'm supposed to be getting those test addresses – Serj Sagan Feb 12 '18 at 8:56

    Wow, so somebody is actually trying to use it? That's great. Feel free to open up an issue on github and let's discuss it there. – mancze Feb 15 '18 at 8:50
  • You have done great job! However it does not work with truffle 5.0 and web3 1.0 anymore. I have updated it to support new truffle: github.com/dukei/token-test-suite – Dmitry Kochin Mar 17 '19 at 20:03

Take a look at the heavily audited ERC20 token contracts found on github.com/ConsenSys/Tokens and github.com/OpenZeppelin/zeppelin-solidity. You'll find extensive tests using truffle.

  • Thanks, I have seen those. The major problem with them they are not designed for code reuse (the tests). So the only way to use them is to copy&paste (and customize). That's not good. – mancze Nov 20 '17 at 13:33
  • @mancze oh gotcha. I haven't seen anything out there like you described. However, it should be pretty simple to take those tests and turn it into a library. – Miguel Mota Nov 20 '17 at 16:20
