We automatically test REST API based on their specifications, particularly OpenAPI ones. To our surprise, many of our tests failed, meaning that the OpenAPI definition and the actual API were not an exact match.
We propose a model-based approach to compose data-driven REST APIs. Our approach creates a global API exposing a unified data model. This global model is exposed as an OData service
We present our new tool OpenAPItoUML to generate UML models from OpenAPI definitions, thus offering a better visualization of the data model and operations of REST APIs. OpenAPItoUML is available as an open source Eclipse plugin.
OData is a protocol to facilitate the publication and consumption of queryable and interoperable data-driven services. OData is based on the use of RESTful APIs derived from a data model. We present a model-driven approach to automate the generation of OData services from data sources
