TFS 2015, Xunit transform to Trx

It turns out I was wrong in my last post about transforming nUnit tests to Trx ( Ms Test ) format for display in TFS 2015. It fails short as the nUnit format that xUnit spits out does not have any console or standard out traces. Therefor when you want to view more information about your tests or error traces on failures non are available. I went down the road to use the nUnit format because TFS was supposed to take it and display it in TFS without tranforming to Trx but that does not work. So the solution is to use the xUnit Xml V2 format by passing the -xml switch to xUnit. Then convert the xml to Trx using your Xslt transform. Mine is here on GitHub if you want a copy.

DNX .Net WebApi Integration testing

I needed to compare some gRPC round trip numbers to plain .Net WebApi. So the question became how to test WepApi round trips from UnitTest harness.

It’s actually pretty simple if you are using the newer DNX libraries. I’m using the TestHost library to get things done.

From project.json

“System.Net.Http”: “4.0.1-beta-23516”,
“Microsoft.AspNet.TestHost”: “1.0.0-rc1-final”,

The UnitTest itself

[Fact]
    public async void PingTheServerRepeat()
    {
      // Setup client & server
      TestServer server = new TestServer(TestServer.CreateBuilder().UseStartup<Startup>());
      HttpClient client = server.CreateClient();

      // Make a request and check response
      var getResponse = await client.GetAsync(“/api/values/5”);
      var response = await getResponse.Content.ReadAsStringAsync();
      Logger.Log(“web api, response=” + response);

      // Hit the webapi, repeatedly
      Stopwatch watch = Stopwatch.StartNew();
      for (int i = 0; i < Util.Repeat; i++)
      {
        getResponse = await client.GetAsync(“/api/values/” + i);
        response = await getResponse.Content.ReadAsStringAsync();
      }
      watch.Stop();
      Logger.Log($“WepApi, round trips={Util.Repeat}, Execution time, millisec={watch.ElapsedMilliseconds}, average roundtrip=” + ((double)watch.ElapsedMilliseconds / Util.Repeat));
      Logger.Log(“web api, response=” + response);

      // Done, release resources
      server.Dispose();
      client.Dispose();
    }
