Truffle: Events logs really interesting even when tests pass.

Created on 29 Jun 2016 · 6Comments · Source: trufflesuite/truffle

Truffle shows events shot by a contract when its test fail. That is really a cool feature that may be interesting even when tests successfully pass.

I personally use Events to understand better how my contract behaves while testing them. For instance:

event Test(uint testID);

function someFunction (address addr, uint _uint) returns (bool) {
        if (a)  { Test(111); return false;}
        if(b)) {Test(112); return false;}   
[...] }

// or 
    for (uint i=0; i<n; i++) {
            if (a(i)) {Test(i); return false;}
        }

I'm currently adding a assert.equal(1,2) at the end to have access to those events, but might be an interesting feature to have.

enhancement help wanted ready

@HCharlanes Good feature. It'd likely need to be added via the console, i.e., truffle test --show-events, or something to that effect. Marking as enhancement and putting on the list of things to work on.
