Given some contract A, that depends on another contract B, what would be the best way to unit test functions from A without inadvertently testing code from B.

Normally, we could use stubs to return data that is the same every time, but this is cumbersome to do manually with even a moderate amount of code (generate, compile, and deploy the stub).

Is there a framework or library out there yet that has this sort of functionality built in?

Also would be happy to provide a code example if the description above is too abstract; just comment.

I'm using:

  • mochajs with chai assertions
  • truffle for a testing framework
  • ethereumjs-testrpc for test network

You can create a stub contract. Deploying it in the test using truffle is not cumbersome. You can do it like so:

token1 = await Token.new()
