How to get a Random Long?

felipetofoli commented 6 months ago

I tried this implementation: "{{Random Type=\"Long\" Min=1000000000 Max=9999999999}}", but I am getting an error, even though 1000000000 and 9999999999 are valid Int64 numbers.

Is this handlebar expression correct? Or do we have a bug when generating Random long numbers?

Following are more details.

Implementation

 var settings = new WireMockServerSettings
{
    AllowPartialMapping = true,
    StartAdminInterface = true,
    Urls = new[] { "http://localhost:3000/", },
    Logger = new WireMockConsoleLogger(),
};

var server = StandAloneApp.Start(settings);

server
    .Given(Request.Create()
        .WithPath(new ExactMatcher("/"))
        .UsingGet())
    .RespondWith(Response.Create()
        .WithStatusCode(200)
        .WithHeader("Content-Type", "application/json")
        .WithBodyAsJson(new
        {
            id = "{{Random Type=\"Long\" Min=1000000000 Max=9999999999}}",
        })
        .WithTransformer());

Console.WriteLine("Press any key to stop the server");
Console.ReadKey();

Response (error)

HTTP/1.1 500 Internal Server Error
Content-Type: application/json
Date: Fri, 08 Dec 2023 16:36:45 GMT
Server: Kestrel
Transfer-Encoding: chunked

{"Status":"Object of type 'System.String' cannot be converted to type 'System.Int64'."}

it's a bug in Handlebars : https://github.com/Handlebars-Net/Handlebars.Net/pull/562

I'll check if I can build a workaround in wiremock
