Setting up an A/A test in GrowthBook is similar to setting up an A/B test. Here are the steps you need to follow: 1. Create an experiment in GrowthBook. Ensure the "variations" are serving the same values. This is what makes it an A/A test, as both variations are identical. 2. Start your experiment just as you would any other experiment. Wait until it has been live for a few hours or days, depending on how much traffic you get, then take a look at the results. Here's a basic example of how you might set up your feature for the A/A test:

javascript if (growthbook.feature("your-feature-name").on) {     // Variation   } else {     // Control   }

Remember to replace

"your-feature-name"

with the name of your feature. For more detailed instructions on setting up an A/B test (which you can follow for an A/A test), you can refer to the [GrowthBook documentation](https://docs.growthbook.io/faq#how-do-i-run-an-ab-test-in-growthbook). If you're new to GrowthBook, you might find it helpful to start with the [Quick Start Guide](https://docs.growthbook.io/quick-start) and the guide on [Setting up GrowthBook](https://docs.growthbook.io/guide/create-react-app-and-growthbook#2-set-up-growthbook). Remember, A/A tests are particularly useful when you've set up a new SDK connection or made changes to any part of the GrowthBook integration. They can help you validate that the experiment data is being sent correctly to your data warehouse.

Yes, in the context of the example provided, the

.on

property of the

feature

method returns a boolean value. This property checks if the assigned value of the feature is "truthy" (i.e., it has a value that is considered true in a boolean context). Here's the relevant code snippet:

javascript if (growthbook.feature("your-feature-name").on) {     // Variation   } else {     // Control   }

In this code,

growthbook.feature("your-feature-name").on

will return a boolean value. If the feature is "on" (truthy), it will return

true

, and the code within the first block (Variation) will be executed. If it's not "on" (falsy), it will return

false

, and the code within the else block (Control) will be executed. You can find more information about this in the [GrowthBook documentation](https://docs.growthbook.io/lib/java#using-features).
