fixture-stdout

fixture-stdout
==============

A test fixture to intercept writes to stdout.

#### Install:
``sh
npm install fixture-stdout
`

#### Example Usage:

`javascript
var StdOutFixture = require('fixture-stdout');
var fixture = new StdOutFixture();

// Keep track of writes so we can check them later..
var _writes = [];

// Capture a write to stdout
fixture.capture( function onWrite (string, encoding, fd) {
_writes.push({
string: string,
encoding: encoding,
fd: fd
});


// If you return false, you'll prevent the write to the original stream (useful for preventing log output during tests.)
return false;

});

// Uses intercepted version of stdout
console.log('a');
console.log('b');

fixture.release();

// Now we're back to the original version of stdout
console.log('c');
console.log('d');

// Voila!
// Only the first two logs ("a" and "b") are in our _writes array
`

#### Watch streams other than stdout:

`javascript
var Fixture = require('fixture-stdout');

var fixture = new Fixture({
stream: process.stderr
});

fixture.capture();
console.error('hello world');
fixture.release();
console.error('world');
