This is an simple react-native app bootstrapped with npx react-native init <projectname> and in order to run you must have an emulator running or an authorized development device connected to your pc. First start the react-native bundler using npx react-native start on the project folder and run on your emulator/device using either npx react-native run-android or npx react-native run-ios.
The chosen test suite was jest and the testing commands are avaliable as yarn test, or simply jest in the project root folder.
