Hello,
Thank you for this great NuGet package! It is awesome!!

During using the package I was faced with following issue:

I start a single WireMockServer and then create two mappings one for /api/Customer/add and another for /api/Customer/update,
also, I use .WithBody((body) => VerifyCrmRequestBody(TestCustomers.Customer1, body))) for both requests mapping.

When no matter what request send to wiremock WithBody executes for both mappings and ignore .WithPath("/api/Customer/add")

Is it correct behavior?
How can I solve this issue and verify WithBody for only a specific URL path?

Package:

 <PackageReference Include="WireMock.Net" Version="1.5.6" />

    // RestEase http client

    [BasePath("/api/Customer")]
    public interface ICustomerCrmClient
    {
        [Post("add")]
        public Task Add([Body] CustomerCrmCreation customer);

        [Put("update")]
        public Task Update([Body] CustomerCrmCreation customer);
    }

    public void Test()
    {
        var wireMockServer = WireMockServer.Start();
        wireMockServer.Given(Request.Create()
                                   .UsingPost()
                                   .WithPath("/api/Customer/add")
                                   .WithBody((body) => VerifyCrmRequestBody(TestCustomers.Customer1, body)))
                        .RespondWith(WireMock.ResponseBuilders.Response.Create().WithStatusCode(HttpStatusCode.OK));

        wireMockServer.Given(Request.Create()
                                    .UsingPut()
                                    .WithPath("/api/Customer/update")
                                    .WithBody((body) => VerifyRequestBody(TestCustomers.Customer1, body)))
                       .RespondWith(WireMock.ResponseBuilders.Response.Create().WithStatusCode(HttpStatusCode.OK));
    }

@khdevnet

When WireMock.Net receives a http request, all mappings are processed in order to find the best match.

So in your case, because the VerifyCrmRequestBody method is used in both mappings, this method is also executed twice because in total you have two mappings.

Thank you for fast reply,

How does it choose the best match?
Is it uses some kind of score?

Case 1
POST /api/Customer/add
{ some body}
.UsingPost() +1
.WithPath("/api/Customer/add") +1
.WithBody("{ some body}") +1
.RespondWith({ some response body})

Score = 3

Case 2
PUT /api/Customer/update
{ some body}
.UsingPut() +0
.WithPath("/api/Customer/update") +0
.WithBody("{ some body}") +1
.RespondWith({ another response body})

Score = 1

because Case 2 has a score 1 then it skips it and returns the result for score 3 ?
what is the response { some response body } ?

In your case when you have 2 mappings, the best matching will be returned.

And indeed, the scoring looks like you defined, not 100% correct, but close.

If you want to know the details on the match, see the logging.

You can also assign a Priority for each mapping to allow you to prioritize one mapping over another when you match multiple times.
