 Type definitions for cordova-plugin-qrscanner are [available in the DefinitelyTyped project](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/cordova-plugin-qrscanner/cordova-plugin-qrscanner.d.ts).
 
 ## Contributing & Testing
-To setup the tests, run `npm test`. This will create a new cordova project in the same directory as this repo, install cordova-plugin-qrscanner, and configure the [Cordova Plugin Test Framework](https://github.com/apache/cordova-plugin-test-framework).
+To setup the tests, run `npm test:ios`. This will create a new cordova project in the same directory as this repo, install cordova-plugin-qrscanner, and configure the [Cordova Plugin Test Framework](https://github.com/apache/cordova-plugin-test-framework).
 
 Both Automatic Tests (via Cordova Plugin Test Framework's built-in [Jasmine](https://github.com/jasmine/jasmine)) and Manual Tests are available. Automatic tests confirm the existence and expected structure of the javascript API, and manual tests should be used to confirm functionality on each platform.
