❔ Issue with unit testing and projects not starting

I'm writing up tests for my controller, but I need to grab an access token for authorization to do anything. We're using OIDC and it's endpoint ishttps://localhost:5001

public async Task < string > GetAccessToken() {
  var client = new HttpClient();

  var request = new HttpRequestMessage(HttpMethod.Post, "https://localhost:5001/connect/token");
  request.Content = new FormUrlEncodedContent(new Dictionary < string, string > {
    ///stuff here
  });

  var response = await client.SendAsync(request);

  if (!response.IsSuccessStatusCode) {
    throw new Exception("Failed to obtain token");
  }

  var responseContent = await response.Content.ReadAsStringAsync();
  var tokenResponse = JsonConvert.DeserializeObject < TokenResponse > (responseContent);

  return tokenResponse.AccessToken;
}

public async Task < string > GetAccessToken() {
  var client = new HttpClient();

  var request = new HttpRequestMessage(HttpMethod.Post, "https://localhost:5001/connect/token");
  request.Content = new FormUrlEncodedContent(new Dictionary < string, string > {
    ///stuff here
  });

  var response = await client.SendAsync(request);

  if (!response.IsSuccessStatusCode) {
    throw new Exception("Failed to obtain token");
  }

  var responseContent = await response.Content.ReadAsStringAsync();
  var tokenResponse = JsonConvert.DeserializeObject < TokenResponse > (responseContent);

  return tokenResponse.AccessToken;
}

When I run this function in test explorer, I get a

 System.Net.Http.HttpRequestException : No connection could be made because the target machine actively refused it. (localhost:5001)

However, when I open a separate instance of VS and run the application, then run test on the 1st VS, everything works fine. How do I make it so that I don't need to do all the shenanigans and just run the test from the test explorer?

    public class AppMenuItemController_Test : IClassFixture<AuthService>
    {
        private readonly IAuthService _authService;
        private string _accessToken;

        public AppMenuItemController_Test(AuthService authService)
        {
            _authService = authService;
        }

        [Fact]
        public async void ShouldGetAccessToken()
        {
            _accessToken = await _authService.GetAccessToken();
            Assert.True(!string.IsNullOrEmpty(_accessToken));
        }
    }

    public class AppMenuItemController_Test : IClassFixture<AuthService>
    {
        private readonly IAuthService _authService;
        private string _accessToken;

        public AppMenuItemController_Test(AuthService authService)
        {
            _authService = authService;
        }

        [Fact]
        public async void ShouldGetAccessToken()
        {
            _accessToken = await _authService.GetAccessToken();
            Assert.True(!string.IsNullOrEmpty(_accessToken));
        }
    }

The code itself is fine, just having issues with my test not running all the startup project

I don't see your test code starting a web service. You'll want to read up on WebApplicationFactory

https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.testing.webapplicationfactory-1?view=aspnetcore-7.0

WebApplicationFactory Class (Microsoft.AspNetCore.Mvc.Testing)

Factory for bootstrapping an application in memory for functional end to end tests.
