    WireMock.Net

    WireMock.Net

    WireMock.Net is a product for stubbing and mocking web HTTP responses

    Free and Open Source tool for building mock APIs. Create stable development environments, isolate yourself from flakey 3rd parties and simulate APIs that don't exist yet. WireMock frees you from dependency on unstable APIs and allows you to develop with confidence. It's easy to launch a mock API server and simulate a host of real-world scenarios and APIs - including REST, SOAP, OAuth2 and more. WireMock is a free API mocking tool that can be run as a standalone server, or in a hosted version via the WireMock Cloud-managed service. API mocking involves creating a simple simulation of an API, accepting the same types of request and returning identically structured responses as the real thing, enabling fast and reliable development and testing.

    OpenAPI.NET

    OpenAPI.NET

    Object model for OpenAPI documents in .NET

    The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme. Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object. Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object.
