Venice - Multivariate Test Bed 

A simple test bed for running multivariate tests. It only provides a way to query experiments and assigning users to a particular variant. You will need to use the manager throughout your code and manually provide the code for each of the variants.

$3

npm install venice

Config

{
"experiment-1": {
"type": "variant",
"variants": [
"control",
"variant-1"
]
}
}

Usage

``javascript
var venice = require('venice');

var definition = {
"experiment-1": {
"type": "variant",
"variants": [
"control",
"variant-1"
]
}
};

var manager = venice.init(definition);

...

/ Alter the functionality for an experiment /

var experiment = manager.get('experiment-1');
if (experiment && experiment.active()) {

switch (experiment.variant()) {

case 'control':
console.log('control');
break;

case 'variant-1':
console.log('variant-1');
break;

}

}
`

The default init method will use cookies to persist the user's session. This makes it unsuitable for use in a CLI app. You can create your own session storage (e.g. in a database) and create an instance of the manager:

`javascript
/ Create an instance of the manager /

var session = {
variant: function() {
// query the database
},
setVariant: function() {
// write to database
}
};

var factory = new venice.Factory(session);

var config = new venice.Config(factory);
config.setDefintion(definition);

var manager = new venice.Manager();
manager.addConfig(config);
