stest - A Sane Async Testing Framework

stest is a fun, fast and simple testing framework particularly suited towards asynchronous code. It lets you easily structure tests for code with both synchronous and asynchronous methods without too much complexity.

Installation:

Using npm:

npm install -g stest

Usage:

A very simple test:

var stest = require("stest"),
    assert = require("assert"),
    mylib = stest.cover("../lib/mylib");

var opts = { timeout: 0 };

stest.addCase("stest", opts,{
    setup: function(promise){

        promise.emit("event", 42);
        promise.emit("other_event", "Hello!");

        mylib.async_func(function(err, obj){
            promise.emit("async", err, obj);
        });
    },
    event: function(fortytwo){
        assert.equal(42, fortytwo);
    },
    other_event: function(hello){
        assert.equal("Hello!", hello);
    },
    async: function(err, obj){
        assert.ifError(err);
        assert.ok(obj);
    },
    teardown: function(errors){
        if(errors.length > 0) assert.ok(0);
    }
}).run();

stest hands you a promise object which is an instance of EventEmitter. Use this to emit events and values when your async/sync calls complete, and check them in the corresponding functions associated with the name of the events you've emitted.

The setup and teardown functions are given to you to setup your test case, and to perform a teardown. setup is required, teardown is optional.

The opts argument allows you to specify a timeout in miliseconds. If all async calls are not called before that time, stest will give you a heads up.

stest also supports code coverage using the cover method, which shows unseen LOC and gives you a brief overview of how much of the file you've tested. Do note that cover may trip up if you have really whacky syntax (like assignments inside of conditional statements and such).

See the source code and inline documentation for more details.

Running Tests:

Tests can be run en masse using srunner:

Usage: srunner [-s] -r [regexp]

Options:
  -s, --silent  supress output           [boolean]
  -r, --regexp  regexp of files to test  [string]  [required]

Which looks like this in the command line:

srunner -r test/test-.*\.js

If you prefer not to use srunner, you can still run tests like this:

node test.js

srunner isn't dependant on stest per se, so it also works really well as a general purpose test runner.
