Development is Better when it's Test-Driven

What this episode covers

Jeff Gable, an embedded software consultant, explains his practice of Test-Driven Development (TDD) to host Luca Ingianni, arguing that writing failing unit tests before application code forces good architecture and high coverage. Gable details how this discipline decouples embedded application logic from hardware-specific drivers, allowing tests to run on the host machine for rapid feedback rather than slow target flashing. He addresses the common industry resistance to TDD in embedded systems, citing the initial learning curve and the need for coaching, while recommending resources like the 'Throw the Switch' video courses and tools such as Unity, CMock, and Ceedling. The conversation concludes by framing TDD as an artistic craft of storytelling through code, emphasizing that the practice builds confidence and prevents regressions in production-quality software.

    30: Eventually Lightning Strikes (Repeat)

    James Grenning, author of 'Test-Driven Development for Embedded C' and founder of Renaissance Software, explains how Test-Driven Development (TDD) improves embedded software engineering by enabling developers to write portable, modular code before hardware is available. He argues that TDD forces early design decisions, such as modularity and interface segregation, which reduces integration bugs and allows engineers to test logic on a PC rather than waiting for target hardware. Grenning also discusses his teaching methodology, emphasizing that engineers should experience TDD themselves to understand its value in reducing late-stage debugging and managing legacy code.

    270: Broccoli Is Good Too

    James Grenning, author of 'Test Driven Development for Embedded C' and founder of Wingman Software, discusses the philosophy and practice of Test Driven Development (TDD) for embedded systems. He explains how TDD reduces debugging time by enforcing small, verifiable steps and using techniques like 'ZOMBIES' to defer complex decisions. Grenning also shares insights from a recent side project involving a Synapse Wireless mesh network for industrial water pressure monitoring, illustrating how to handle hardware uncertainty through experimentation and loose coupling.

    30: Eventually Lightning Strikes

    James Grenning, author of 'Test Driven Development for Embedded C' and founder of Renaissance Software, explains how TDD reduces bugs and improves design in embedded systems. He argues that manual testing is unsustainable because the cost of retesting grows exponentially, leading to hidden defects that cause late-stage failures. Grenning advocates for getting code off the target hardware to run on PCs using mocks and fakes, which forces modularity and allows engineers to build confidence before hardware is available. He emphasizes that TDD is not just about testing but about driving SOLID design principles, such as single responsibility, by making complex code difficult to test.

    109: Resurrection of Extreme Programming (Repeat)

    James Grenning, founder of Wingman Software and author of 'TDD for Embedded C', discusses the resurgence of Extreme Programming and Test-Driven Development (TDD) for embedded engineers. He explains how TDD prevents bugs and improves code quality, contrasting it with the micromanagement often associated with modern Scrum. Grenning also details his methods for teaching TDD, including the use of CyberDojo for remote training and 'Training from the Back of the Room' techniques to engage students.

    103: Tentacles Of the Kraken

    Mark VanderVoord, lead maintainer of the open source testing frameworks Unity and CMock, explains how test-driven development (TDD) and mocking help embedded engineers design better code without needing full hardware simulators. He details the workflow of using CMock to generate fake interfaces for hardware drivers like I2C, allowing developers to test logic in a native host environment. VanderVoord also discusses the challenges of maintaining these tools, his new online course on ThrowTheSwitch.org, and the business model of supporting free open source projects through books and classes.
