Course Overview

The TDD and Embedded Systems course by Koenig Original is designed for embedded software developers, firmware engineers, and technical team leads seeking to implement robust, test-first development practices in resource-constrained environments. While no official certification exam is tied directly to this Koenig Original offering, the training aligns closely with industry best practices validated by leaders in embedded systems such as NASA and Bosch, where adoption of Test-Driven Development (TDD) has reduced defect rates by up to 50%. This course equips professionals with the skills to write reliable firmware using the Red-Green-Refactor cycle, apply hardware abstraction patterns, and develop testable C/C++ code—critical competencies for roles involving safety-critical or real-time systems.

Participants engage with key tools and frameworks including Unity, CppUTest, and embedded-specific test doubles such as mocks, fakes, and spies, all within a dual-target testing environment that supports both host-based simulation and target platform validation. The hands-on lab component centers on building a complete embedded system from scratch—such as a traffic light controller or sensor driver—where students practice writing tests before implementation, mocking hardware peripherals, and integrating automated tests into a CI/CD pipeline. Using live remote labs accessible via standard internet connectivity, learners configure real-world scenarios like time abstraction, link-time substitution, and refactoring legacy firmware, ensuring practical mastery of TDD techniques tailored to embedded constraints.

By completing the TDD and Embedded Systems course, attendees gain expertise recognized across industries including automotive, medical devices, and industrial automation, where demand for high-integrity code continues to grow. Graduates report career advancements such as transitioning into senior developer or software architect roles, often accompanied by salary increases of 15–25% based on industry benchmarks. A key differentiator at Koenig Solutions is the Guaranteed-to-Run delivery model and access to expert-led, small-group instruction that ensures personalized feedback. Upon completion, professionals are equipped to lead TDD adoption in their teams, delivering higher-quality embedded software with faster time-to-market and long-term maintainability.
