How can I create instance of HttpRequestHeaders class

Question

I have to unit test class that use HttpRequestHeaders as parameter.

    public HeaderValueProvider(HttpRequestHeaders headers)     {         _headers = headers;     } 

Answer 1

HttpRequestHeaders has only internal constructor. But you can do it by creating HttpRequestMesssage object:

using var headers = new HttpRequestMessage().Headers; 

Answer 2

You can get a blank instance of HttpRequestHeaders via:

var headers = new HttpClient().DefaultRequestHeaders;
