Mobile App Performance Testing

1. Introduction

Mobile App Performance Testing is a critical aspect of ensuring that mobile applications provide a smooth and efficient user experience. It involves testing the app's responsiveness, speed, scalability, and stability under various conditions.

2. Key Concepts

**Performance Metrics**: Key performance indicators include load time, response time, and data usage.
**Load Testing**: Evaluating how the app performs under expected user loads.
**Stress Testing**: Determining the app's breaking point by subjecting it to extreme conditions.
**Scalability Testing**: Assessing how well the app scales with increasing user load.
