Install all dependencies with yarn which will also run pod install on post install. You should be able to run both yarn ios and yarn android to run respective iOS and Android simulations of the application.

The application highlights multiples of a selected number in a 1-144 grid — for instance the multiples of 38 are 76 and 114. Numbers highlighted in yellow are the multiples, and in green is the currently selected number we're displaying the multiples for.

Whilst the application functions correctly, and the developer has put together a handful of unit tests; the application doesn't yet have any integration tests. Please put together an integration test suite for the application, to ensure the app is stable and that it behaves correctly on interactions for the debug build.

It doesn't matter which library you choose to write the integration tests, but popular ones include Detox and Appium.

Once you've created the integration tests, please allow them to be run using the yarn integration command.
