AssertionError - output is noisy. How do I show only Assertion

Question

When running the Intern Unit test example from Getting Started, when I changed the Hello unit script and ran it so it assert, it appears to be showing more detail (noisy) than what I need. Is this output correct? Is there a way to only show the AssertionError line and maybe the file / line where this assertion occurred?

unit_hello.js:

define([
    'intern!object',
    'intern/chai!assert',
    'app/hello'
], function (registerSuite, assert, hello) {
registerSuite({
    name: 'hello',

    greet: function () {
        assert.strictEqual(hello.greet('Name'), 'Hello, Name!',
            'hello.greet should return a greeting for the person name in the first argument');
        assert.strictEqual(hello.greet(), 'Hello, World!',
            'hello.greet with no arguments should return a greeting to "world"');
        }
    });
});

Output:

user@pcname:~/intern_example$ ./node_modules/.bin/intern-client config=tests/intern_unit
FAIL: main - hello - greet (1ms)
AssertionError: hello.greet with no arguments should return a greeting to "world":  expected 'Hello, world!' to equal 'Hello, World!'

You can write and load your own custom reporter to output whatever information you want or don’t want. The standard reporters will always provide a full stack trace.
