如何将客户端证书附加到AspNetCore TestServer api？

Question

I'm looking at Microsoft.AspNetCore.TestHost.TestServer in the Microsoft source code. There I see the CreateClient() property that is HttpClient objects.

So how do I attached the client certificate for Digitial Signature in xUnit Test?

HttpClient example would be this.

var x509Certificate2 = new X509Certificate();  // Pretend it contains certificate data already.

var httpClientHandler = new HttpClientHandler() {
    ClientCertificateOptions = ClientCertificateOption.Manual
};
httpClientHandler.ClientCertificates.Add(x509Certificate2);

using (var httpClient = new HttpClient(httpClientHandler))
{
}

Now using the TestServer

var testServer = new TestServer();

testServer.CreateClient();  // How do I attached client certificate here?

So, how do we attach the client certificate here? For CreateClient()

Also, I can try to make do with implementing the HttpRequestMessage but it doesn't support that certificate option either.

You may try to use the testServer.SendAsync(...) method and just construct your HttpContext from there.

var result = await server.SendAsync(context =>
                                    {
                                        context.Connection.ClientCertificate = myClientCertificate;
                                        context.Request.Method = "POST";
                                     });

Just make sure to specify the Path and the Body as needed.
