Using WireMock in integration tests does not pick up the SerializerSettings defined in the StartUp

In the Startup:

.AddNewtonsoftJson(x => x.SerializerSettings.NullValueHandling = NullValueHandling.Ignore)

The integration test custom WebApplicationFactory (which is then used with the Startup of course):

public class IntegrationTestWebApiFactory<TStartup> : WebApplicationFactory<TStartup> where TStartup : class
{
    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        const string url = "http://localhost:60007";
        
        builder.ConfigureTestServices(
        services =>
            {
             // other stuff
               
             services.AddSingleton(_ => WireMockServer.Start(url)); // hoped it would pick up the json settings... nope!
            });

The issue is then that the WireMockServer does not pick up the json settings (null ignore) set in the startup (I see null fields in the wireMockServer.MappingModels, whereas my API does not serialize nulls, as expected from startup settings)

I’ve found a way around it but I would like to know if it’s possible for WireMockServer to pick up the json settings defined in startup I did this just after the const string url line:

JsonConvert.DefaultSettings = () => new JsonSerializerSettings
        {
            // settings must be aligned on the settings defined in startup. Annoying! Is there a better way?
            NullValueHandling = NullValueHandling.Ignore
        };

Oh, I meant please do as you suggested:

… I update the settings to include a new setting JsonSerializerSettings which you can override as you like.

Pls also update the doc as I suggested.

Was caught with things, so did not take the time to follow up, but you did 👍 Thank you very much. I’ll try the new nuget as soon as released.
