Hello guys,

In WireMock.NET there is a possibility to define scenarios which acts as a state machine for requests. Very nice 👍

Is there possibility at run-time (hosted by Azure/IIS) route requests to specific pre-loaded scenarios based on some request attribute like header, param, etc.?
Or at least switch mock server to use specific scenario for specific url path (in case of N scenarios for same path) by calling __admin endpoints ?

Currently I found only __admin endpoints to manage collection of scenarios on the server like POST,GET,DELETE. But nothing like ability to switch to use some scenario depending on... request attribute or calling some __admin endpoint.

So my questions:

Could that behavior be achieved by dynamically managing Scenarios collection on the server?
Say on top of wiremock server there some other API running and exposing endpoint like POST api/scenarios/{name}/use which will clear Scenarios collection and load only scenario with {name}
Is it possible to do some side-effect action (Action<> like) on .Given(..) when creating mappings?

Hey mates,

Still didn't get any answers, but I found how to inject custom Owin middleware if you need to have custom behavior. In my case I do it like this:

// Add access to IFluentMockServerSettings
var settings = configuration.GetSection("FluentMockServerSettings").Get<FluentMockServerSettings>();
settings.PreWireMockMiddlewareInit = app => 
{
    ((IApplicationBuilder)app).UseMiddleware<MyCustomMiddleware>();
};
services.AddSingleton<IFluentMockServerSettings>(settings);

This is indeed also an option to introduce custom logic. I'll add this to the wiki.
