How to call node.js REST API from .NET - asp.net

Question

If I put the jquery code below within the script tag within a html page and drag the html page into a web browser the call to the API specified in the URL is made and I get back a response in JSON format. So this works good.
The reason I want to use .NET for calling the rest API that is made in node.js is because I want to use the unit test utility that exist in visual studio.
So when I start the unit test the call to the REST API made in node.js should be made and then I can check whatever I want in the returned json format by using the assert.AreEqual.
I have googled a lot and there is several example about
Unit Testing Controllers in ASP.NET Web API 2 but I don't want to unit test controller. I only want to call the REST API(made in node.js) when I start my unit test.
I assume to use .NET in the way I want is probably quite rare.
If it's not possible to use .NET and unit test in the way that I want here
I will use another test framework.
I hope to get some help from here.
Hope you understand what I mean.
$.ajax({
type: 'GET',
url: 'http://10.1.23.168:3000/api/v1/users/1',
dataType: 'json',
async: false,
headers: {
'Authorization': 'Basic ' + btoa('DEFAULT/user:password')
},
success: function(response) {
//your success code
console.log(response);
},
error: function (err) {
//your error code
console.log(err);
}
});
Many thanks

Answer 1

Basically what you need to do is to call node.js' API from your C# test code in a same way you call it using jQuery. There are several ways to do it:
Use HttpWebRequest class https://msdn.microsoft.com/en-us/library/system.net.httpwebrequest%28v=vs.110%29.aspx
Use HttpClient class https://msdn.microsoft.com/en-us/library/system.net.http.httpclient%28v=vs.118%29.aspx It's more "RESTable" since it exposes methods to call HTTP methods like GET, PUT, POST and DELETE methods directly.

Generally I recommend approach #2.

Here's the example source with all the rest of the code.
Another resource is the docs.
This code snippet should be enough to get you where you need.
using(var client = newHttpClient())
{
client.BaseAddress = newUri("http://localhost:55587/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(newMediaTypeWithQualityHeaderValue("application/json"));
//GET Method
HttpResponseMessage response = awaitclient.GetAsync("api/Department/1");
if (response.IsSuccessStatusCode)
{
Departmentdepartment = awaitresponse.Content.ReadAsAsync < Department > ();
Console.WriteLine("Id:{0}\tName:{1}", department.DepartmentId, department.DepartmentName);
Console.WriteLine("No of Employee in Department: {0}", department.Employees.Count);
}
else
{
Console.WriteLine("Internal server Error");
}
}
