rn-test-exception-handler

A react native module to purposefully raise a Native Exception to try and crash the app.

This was basically created by me to test my other library: https://github.com/master-atul/react-native-exception-handler

DO NOT USE IN PRODUCTION - I mean why will you use it production ? 😂

Getting started

$ npm install rn-test-exception-handler --save

Mostly automatic installation

$ react-native link rn-test-exception-handler

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ rn-test-exception-handler and add RnTestExceptionHandler.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRnTestExceptionHandler.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import com.masteratul.rn.testexception.RnTestExceptionHandlerPackage; to the imports at the top of the file
• Add new RnTestExceptionHandlerPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':rn-test-exception-handler'
   project(':rn-test-exception-handler').projectDir = new File(rootProject.projectDir, 	'../node_modules/rn-test-exception-handler/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':rn-test-exception-handler')
   

Usage

import RnTestExceptionHandler from 'rn-test-exception-handler';


RnTestExceptionHandler.raiseTestNativeError();

When you call RnTestExceptionHandler.raiseTestNativeError();

The module basically raises a native exception in both iOS and Android.

How it does it?

RnTestExceptionHandler.raiseTestNativeError(); causes:

In Android

@ReactMethod
public void raiseTestNativeError() throws Exception {
  throw new Exception("TEST EXCEPTION ON ANDROID");
}

In iOS

RCT_EXPORT_METHOD(raiseTestNativeError) {
    NSLog(@"RAISING A TEST EXCEPTION");
    [NSException raise:@"TEST EXCEPTION" format:@"THIS IS A TEST EXCEPTION"];
}
