Question

I am using Chai.js on Node.
The line console.log(e) where e is an exception thrown by Chai.js print something like expected a to be within 0..3.
How can I make the exception of Chai.js include stack trace info?

Answer 1

I found the answer. I can config chai to enable stack trace.
Here’s the code on assertion styles page of chai.

var chai = require('chai');
chai.Assertion.includeStack = true; // defaults to false
