mocha with nodejs assert hangs/timeouts for assert(false) instead of error

Question

I have this kind of a mocha test:

describe \'sabah\', →
    beforeEach →
        @sabahStrategy = _.filter(@strats, { name: \'sabah2\' })[0]
            .str         


        

Answer 1

When I use Highland.js with a super simple test, Mocha catches the failing assert without any problem:

var _ = require("highland");
var fs = require("fs");
var assert = require("assert");

describe("test", function () {
    it("test", function (done) {
        var s = _([1, 2, 3, 4]);
        s.pull(function (err, result) {
            console.log(result);
            assert(false);
            done();
        });
    });
});

This suggests that the problem in your example is not Mocha, nor Highland.js. If the articleLinkStream object (or articleSream; it seems to change from snippet to snippet) is custom code then maybe that code is buggy and actually swallows exceptions rather than let them move up the stack.
