Install
npm install ab-testing
Initialize
var ABTesting = require('ab-testing');
var testObject = ABTesting.createTest('firstTest', // This name has to be unique across all the tests
[
{
name: 'A',
weight: 0.1 // If not set, the default value is 0.5
},
{
name: 'B',
weight: 0.9
}
]);
Assign a group
// Given a unique ID of the user, returns 'A' or 'B'
var testGroup = testObject.getGroup(user.id);
Get test name
// Returns the name of the test, in this case 'firstTest'
var testName = testObject.getName();
A/B Test
// Executes the corresponding function for the given group
testObject.test(testGroup, [
function () {
// Test A code here
},
function() {
// Test B code here
}
], this);
Useful usage tips
// Use the test name and the group name to track analytics
sendToAnalytics(testName, testGroup);
Create multiple A/B tests
var ABTesting = require('ab-testing');
var landingPageTest = ABTesting.createTest('landingPage', [{ name: 'oldLandingPage' }, { name: 'newLandingPage' }]);
var pricingPageTest = ABTesting.createTest('pricingPage', [{ name: 'oldPricingPage' }, { name: 'newPricingPage' }]);
...
var landingPageGroup = landingPageTest.getGroup(req.account.username);
var pricingPageGroup = pricingPageTest.getGroup(req.account.username);
...
landingPageTest.test(landingPageGroup, [
function () {
// oldLandingPage code
},
function () {
// newLandingPage code
}
], this);
pricingPageTest.test(pricingPageGroup, [
function () {
// oldPricingPage code
},
function () {
// newPricingPage code
}
], this);
