SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the challenges of testing embedded systems firmware, enabling robust testing without direct hardware dependencies and facilitating Hardware-in-the-Loop (HIL) setups.

Core Features & Use Cases

Host-based Testing: Execute firmware logic on a development machine using mocks for hardware peripherals.
Hardware Abstraction: Facilitates testing by abstracting hardware interactions through interfaces.
HIL Integration: Provides patterns for setting up Hardware-in-the-Loop test environments.
Use Case: Test the core logic of a sensor driver on your PC before deploying to the target microcontroller, mocking the I2C communication.

Quick Start

Use the embedded-testing skill to create a mock for the GPIOInterface and test the LED class.

FAQPage Schema

How do I test firmware logic without physical hardware?▼

Host-based testing allows you to execute firmware logic on a development machine by mocking hardware peripherals. This enables deterministic testing and efficient feedback loops without requiring physical hardware or a target microcontroller.

Can I use GTest and GMock for embedded systems unit testing?▼

Yes, GTest and GMock are used for host-based unit testing of embedded firmware. By mocking hardware dependencies through abstraction layers, you can run firmware logic tests directly on your development machine for efficient feedback loops.

What is the best way to set up Hardware-in-the-Loop testing for embedded systems?▼

Hardware-in-the-Loop (HIL) testing is facilitated by applying specific integration patterns to create a HIL test suite. This approach tests timing-critical and peripheral integration issues while satisfying requirements for deterministic testing and testability through abstraction.

Why does my embedded test suite fail when I mock I2C communication?▼

Debugging timing-critical or peripheral integration issues requires careful abstraction of hardware interactions. Ensure your mocks accurately represent the hardware dependencies and that your architecture is designed for testability through proper interface abstraction.
