A/B Testing

Use feature flags to test different UI designs and measure performance

Live A/B Test Example

Toggle the 'modern-ui-design' flag in your dashboard to switch between designs

The design automatically updates when you change the flag status

Implementation

How to implement A/B testing with feature flags

Basic A/B Test

// A/B Testing with Feature Flags
const sdk = new FlagVaultSDK({ apiKey: 'test_your-api-key' });

if (await sdk.isEnabled('new-checkout-flow')) {
  // Show new checkout design
  return <NewCheckoutFlow />;
} else {
  // Show current checkout design
  return <CurrentCheckoutFlow />;
}

Conversion Tracking

// Track conversion metrics for A/B tests
async function trackCheckoutConversion(variant: 'control' | 'treatment') {
  // Track which variant led to conversion
  analytics.track('checkout_completed', {
    variant,
    flag: 'new-checkout-flow',
    timestamp: new Date().toISOString()
  });
}

// In your component
const isNewCheckout = await sdk.isEnabled('new-checkout-flow');
const variant = isNewCheckout ? 'treatment' : 'control';

// On successful checkout
await trackCheckoutConversion(variant);

A/B Testing Best Practices

Tips for running successful A/B tests

Test Setup

•Define clear success metrics before starting
•Test one variable at a time for clear results
•Ensure adequate sample size for significance
•Run tests for complete business cycles

Using Feature Flags

•Instant rollback if issues arise
•No code deployment needed to switch variants
•Test in production with real user behavior
•Gradual rollout with percentage controls
