Is there a way to create json mapping from existing yaml OpenApi ?
Thank you

No sorry, this is not yet possible. I had this idea before, but not yet implemented.

Maybe you can also think about this?

What needs to be done is just parsing the YML and generating an JSON with mappings.

A possible option could be to use https://github.com/microsoft/OpenAPI.NET to deserialize the yml to an object (OpenApiDocument) and convert that to a MappingModel object

How can I convert a OpenApiDocument to a MappingModel object ? is this possible with a WireMock helper or should I do it myself ?

I'm working on some proto type code, I keep you informed.

Should this code be added to WireMock?
Or a separate commandline application, or just a NuGet with a library?

I think the best way is to add it as a feature in WireMock
I've started a try but this needs to be improved

public List<MappingModel> ConvertOpenApiDoc(OpenApiDocument document)
{
	var mappinModels = 
		document.Paths.SelectMany(path => // for each path 
		   path.Value.Operations.SelectMany(operation => // for each operation like (post, get, put...)
		   {
			   var example = operation.Value.RequestBody.Content.SelectMany(content => content.Value.Examples.Select(example => example.Value)).FirstOrDefault();
			   return operation.Value.Responses.Select(response => // for each response
				   new MappingModel
				   {
					   Guid = Guid.NewGuid(),
					   Title = path.Key,
					   Request = new RequestModel { Methods = new[] { operation.Key.ToString() }, Path = path.Key, Body = new BodyModel { Matcher = new MatcherModel { Pattern = example.Value } } },
					   Response = new ResponseModel { StatusCode = int.Parse(response.Key), Body = null }
				   });
		   }));

	return mappinModels.ToList();
}

See this project:
https://github.com/WireMock-Net/WireMock.Net.OpenApiParser/tree/master/example/YamlDotNetConsoleApp/YamlDotNetConsoleApp

It currently supports reading a schema and creating dummy data. Or it also supports examples.

Some improvements need to be made like better dummy data for objects and more support for other types.

But it's a start.

@hsnsalhi

I started a new project : https://github.com/WireMock-Net/WireMock.Net/tree/master/src/WireMock.Net.OpenApiParser

And you can try the console-app: https://github.com/WireMock-Net/WireMock.Net/tree/master/examples/WireMock.Net.OpenApiParser.ConsoleApp

In case you need more functionality, just create an issue.
