The examples take a function, while your sample code calls a function and passes the result. The exception happens before the assert even gets to look at it.

Change your code to this:

var assert = require('assert');

function boom(){
    throw new Error('BOOM');
}

assert.throws( boom, Error ); // note no parentheses

EDIT: To pass parameters, just make another function. After all, this is javascript!

var assert = require('assert');

function boom(blowup){
    if(blowup)
        throw new Error('BOOM');
}

assert.throws( function() { boom(true); }, Error );
