Adopting Test-Driven Development in Embedded Systems
Embedded software development has long been characterized by unique constraints such as limited resources, strict real-time requirements, and complex interactions with hardware. As a result, traditional software development methodologies often fail to translate smoothly into the embedded space. However, modern embedded development is evolving, and techniques like Test-Driven Development (TDD) are no longer just for web and enterprise applications: they're essential for building reliable and maintainable embedded systems.
