We present Jolie Checker Toolchain (JCT), a plugin-based toolchain for model-code consistency and compliance analysis aimed at helping developers ensure that evolving implementations of Jolie microservices remain aligned with their intended architectural design—specified with domain- and model-driven engineering approaches like LEMMA and MDSL. One of JCT’s strengths lies in providing a uniform surface for plugin development, based on the analysis of abstract syntax trees, that leverages existing code generation tools, framing checks as correspondence relations between the expected and actual programs. We present two JCT plugins to respectively check the consistency of domain-driven design annotations on Jolie APIs and verify Jolie code conformity to a given LEMMA data model. We illustrate both plugins via a use case drawn from the Lakeside Mutual architecture.
