During March 2026, Sesc developed a FakeEthercat testing interface for the bazel-central-registry repository, enabling continuous integration and unit testing of Etherlab interfaces without requiring physical hardware. Sesc’s approach involved implementing a fakeethercat module in C++ and integrating the librtipc dependency to support the new testing workflow. To ensure compatibility with clang-based builds, Sesc updated string type usage throughout the codebase. Leveraging expertise in the Bazel build system and modern testing frameworks, Sesc expanded the project’s CI coverage, reducing hardware bottlenecks and accelerating validation cycles. This work delivered a focused, maintainable solution for Etherlab-related automated testing scenarios.
