trap

A simpler way to test your code.

trap

trap is simply the most dead-simple test framework you can pick up. It builds and simplifies the already simple structure of of node-tap or tape, but is extensible like mocha.

Two things: test, and t.cb. It's really that simple. You can use the assertion framework you already know. By default trap uses the standard node assertion library. To run the tests in single file, just node the file.

Like tap, we make new test blocks with the test function.

var test = require('trap').test;
 
test('This is a test block!', function (t) {
  t.test('This is a child test block!', function (t) {
    // continue to your heart's content. 
  });
});

Unlike tap, you don't need to figure out when your async tests are done runnning, nor do you need to count how many assertions you have and plan them. Instead, simply register all of your callbacks with t.cb.

var test = require('trap').test;
 
test('Async stuff', function (t) {
  setTimeout(t.cb(function() {
    t.ok(true, 'This is still part of the "Async stuff" test!');
  }), 100);
});

To get the maximum prettiness and documentation of trap, customize config.createAssertionWrapper to wrap your favorite assertion library. Otherwise you can just throw exceptions like you normally do, and those will be interpreted as assertion failures. Hopefully soon we can get plugins for all the major assertion libraries so this will be even easier.
