Cannot call web api 2 post method with int parameter in URL in Unit Test using Http server

Please ignore the spelling mistake, I cannot copy code so I have typed the whole thing and changed name of controller and method.

WEB API 2

Controller:

// Controller name is Test
public HttpResponseMessage Method1(int param1)   // Post method
{
    // return string
}

If I create an object of controller in test case then it is working fine. But if I want to test in localhost using following code:

Unit Test:

public void Method1Test()
{
    HttpResponseMessage response;
    HttpConfiguration config = new HttpConfiguration();
    config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}");
    HttpServer server = new HttpServer(config);
    using(var client = new HttpClient(server))
    {
        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:5022/api/test?param1=1");
        request.Content = new ObjectContent<int>(param1, new JsonMediaTypeFormatter());
        response = client.SendAsync(request, CancellationToken.None).Result;
    };
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
}

Now, my test case is failing. I used the same code in different project and it worked. May be it is the way I am trying to call Post method. Is this the right way to call post method with Int parameter in URL?

In help page, under API column it shows:

POST api/test/param1={param1}

Also I have put some stop point in actual service I am cursor is not stopping at that point. Why?

If I want to call the same service from browser, what URL should I pass? Is it -

http://localhost:5022/api/test?param1=1

Or something else?
