Tip: Not all features need to be implemented at once. Start with MVP (minimum viable product).
Thorough testing makes sure that your application works as planned.
1. Development Testing
- Unit testing
- Integration testing
- User Interface Testing
- Performance testing
2. User Testing
- Beta testing setup
- Feedback Collection
- Bug tracking
- Performance monitoring
3. Cross-Platform Testing
- Test on multiple devices.
- Check various OS versions.
- Check different network conditions.
- Test the offline functionality.
(It is critical to document all bugs and issues for a systematic solution.)
The final step to make your mini-app accessible to users:
1. Preparation
