## README

better-expect
=============

Assert-style handling of exceptions, modeled after
[better-assert](https://github.com/visionmedia/better-assert) for
self-documenting failure messages.

Basically does the opposit of `assert`, by expecting an error to be thrown.

Installation
------------

    $ npm install better-expect

Example
-------

As with better-assert, expectations can be deactivated with the __NO_ASSERT__
environmental variable.

```js
var expect = require('better-expect');

function test() {
  throw new Error();
};

expect(Error, test);
// (passes)

expect(Error, function() { return; });
// ExpectationError: Error, function() { return; }
//    at Object.<anonymous> (~/better-expect/example.js:8:1)
//    at Module._compile (module.js:449:26)
//    at Object.Module._extensions..js (module.js:467:10)
//    at Module.load (module.js:356:32)
//    at Function.Module._load (module.js:312:12)
//    at Module.runMain (module.js:492:10)
//    at process.startup.processNextTick.process._tickCallback (node.js:244:9)
```
