单元测试.net Web Api。 设置查询字符串值

Question

The first line of my ApiController HttpGet action is this

var returnOnlyDefault = (Request.GetQueryNameValuePairs()
    .Any(kv => ((kv.Key.ToLower() == "defaultview") && (kv.Value.ToLower() == "true"))));

This looks for a query string value of "defaultview". The code 'works', but i'm having trouble unit testing it.

In my unit test i am doing the following

var controller = new Controllers.ViewsController { Request = new HttpRequestMessage() };
controller.Request.Properties.Add(new KeyValuePair<string, object>("defaultview", "true"));

the request uri is null of course. The test is failing as it doesn't pick up the query string value.

Answer 1

You should set the request Uri:

controller.Request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:51083/?param1=someValue&param2=anotherValue");

Now the get querystring params in your ApiController works as expected:

var queryStringParams = Request.GetQueryNameValuePairs().ToList();
var param1 = queryStringParams.FirstOrDefault(kv => kv.Key.Equals("param1")).Value;

param1 is now 'someValue' and the unit test runs.
