A/B Testing

The simplest A/B Testing library

Create an experiment, set some options for them, and test the user's behaviour asap!

This A/B Testing library just runs on the device. So:

  • The setup is simple: just use the library. No need to setup a companion server to run experiments.
  • Marketing team can't change your lovely app on the fly. Zero bugs created by avoiding app testing.

To run experiments, we suggest you to wrap the library with your business needs, and use that wrapper from your app. For example:

object ABTestingWrapper {

    private val EXPERIMENT_PRICE_AT_PURCHASE_FUNNEL = "Buy button label in the 'Be PRO' onboarding"
    private val OPTION_SHOW_BUY_WORD = "Show the 'buy' label"
    private val OPTION_SHOW_PRICE = "Show the SKU price"

    fun init(context: Context) {
        val buyOrPriceAtPurchaseFunnel = Experiment(EXPERIMENT_PRICE_AT_PURCHASE_FUNNEL,
                asList(OPTION_SHOW_BUY_WORD, OPTION_SHOW_PRICE))

        ABTestingAndroid.init(context, listOf(buyOrPriceAtPurchaseFunnel))
    }

    fun showPriceAtPurchaseFunnel(): Boolean {
        return ABTestingAndroid.getCurrentOptionFor(EXPERIMENT_PRICE_AT_PURCHASE_FUNNEL) == OPTION_SHOW_PRICE
    }
}

To track results, just call ABTestingAndroid.getCurrentOptions() to get all the experiments and the option set to that user. For example, if you track events using Fabric, you could write something like this:

fun populateExperimentCustomAttributes(event: AnswersEvent<*>) {
    for (currentOption in ABTestingAndroid.getCurrentOptions()) {
        event.putCustomAttribute("Experiment ${currentOption.experiment}", currentOption.option)
    }
}
