Purpose of this Guide: Providing a Comprehensive Understanding of Integration Testing

This guide introduces integration testing and outlines various strategies for conducting it effectively.

Understanding different approaches to integration testing is crucial for successful firmware validation.

Big Bang: Simultaneous Integration of All Components

The ‘Top-down’ approach begins with high-level components, gradually integrating them downwards.

Conversely, the ‘Bottom-up’ strategy starts with low-level components and builds upwards towards complete integration.
