Мне нужен юнит-тест RequestToken метод, который использует HttpClient и метод расширения RequestPasswordTokenAsync.
У меня есть исключение null, даже когда delegatingHandler передается в HttpClient.
var delegatingHandler = new DelegatingHandlerStub(false);
var httpClient = new HttpClient(delegatingHandler);
var tokenServices = new TokenServices(httpClient)
tokenServices.RequestToken(passwordTokenRequest); //exception
public class TokenServices : ITokenServices
{
private readonly HttpClient _httpClient;
public TokenServices(HttpClient httpClient)
{
_httpClient = httpClient;
}
public async Task<TokenResponse> RequestToken(PasswordTokenRequest request)
{
var response = await _httpClient.RequestPasswordTokenAsync(request);
}
}
public class DelegatingHandlerStub : DelegatingHandler
{
private readonly Func<HttpRequestMessage, CancellationToken, Task<HttpResponseMessage>> _handlerFunc;
public DelegatingHandlerStub(bool toThrowException)
{
_handlerFunc = (request, cancellationToken) =>
{
if (toThrowException)
throw new Exception();
return Task.FromResult(request.CreateResponse(HttpStatusCode.OK));
};
}
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
return _handlerFunc(request, cancellationToken);
}
}
namespace IdentityModel.Client
{
public static class HttpClientTokenRequestExtensions
{
public static Task<TokenResponse> RequestPasswordTokenAsync(this HttpMessageInvoker client, PasswordTokenRequest request, CancellationToken cancellationToken = default(CancellationToken));
}
}
