Evaluation.OpenAPI 0.1.3-pre-b1017338

OpenAPI.Evaluation

Evaluates API requests and responses against OpenAPI 3.1 specifications using a custom System.Net.Http.DelegatingHandler.

Installation

dotnet add package OpenAPI.Evaluation

https://www.nuget.org/packages/OpenAPI.Evaluation/

Getting Started

Load the OpenAPI specification and create a HttpClient.

var stream = File.OpenRead("path/to/openapi-specification.json");
var document = JsonNode.Parse(stream);               
var specification = Specification.OpenAPI.Parse(document);
var evaluationOptions = new EvaluationOptions();
var client = new HttpClient(
    new EvaluationHandler(
        specification,
        evaluationOptions,
        new HttpClientHandler()));

When sending a request the HttpResponseMessage will be wrapped by a EvaluationHttpResponseMessage that contains the evaluation results in the property EvaluationResults. If the HttpRequestMessage fails evaluation the handler will return a EvaluationHttpResponseMessage with a BadRequest response and never send the request to the server.

If you rather prefer failed evaluations to throw and exception, this is configurable in the EvaluationOptions.

Yaml

To load a yaml formatted specification, I recommend Yaml2JsonNode.

var yaml = new YamlStream();
using var reader = File.OpenText("path/to/openapi-specification.yaml");
yaml.Load(reader);
var document = yaml.ToJsonNode().First();
