Testing Apps


The GenHTTP.Testing package provides an easy way to write component tests for your application using a test framework of your choice. It provides both the ability to host your project in an isolated mode as well as convenience methods to run HTTP requests against your server.

NOTE Projects created via project templates already feature a basic test setup.

Writing Tests

The following code shows how the TestHost can be used to spin up a server instance hosting the functionality of the app to be tested and how to run requests against this instance.

using GenHTTP.Testing;
    public sealed class MyTests
        public async Task TestMyApp()
            var app = ... // setup your app here
            using var runner = TestHost.Run(app);
            using var response = await runner.GetResponseAsync("/some/path");
            Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);

The framework uses the HttpClient to execute requests, so that the semantics are the same, e.g. when performing POST requests with a body:

var request = runner.GetRequest();
    request.Method = HttpMethod.Post;
    request.Content = new StringContent("My Body");
    using var response = await runner.GetResponseAsync(request);
