Building Microservices with .NET Core

Integration tests

In ProductService, let's make sure that our service returns the product data without failure:

    namespace FlixOne.BookStore.ProductService.IntegrationTests.Services    {        public class ProductTest        {            public ProductTest()            {                // Arrange                _server = new TestServer(new WebHostBuilder()                    .UseStartup<Startup>());                _client = _server.CreateClient();                _client.BaseAddress = new Uri("http://localhost:20077");            }            private readonly HttpClient _client;            private readonly TestServer _server;            [Fact]            public async Task ReturnHelloWorld()            {                // Act                var response = await _client.GetAsync("/GetProduct");                response.EnsureSuccessStatusCode();                var responseString = await     response.Content.ReadAsStringAsync();                // Assert                Assert.NotEmpty(responseString);            }        }    }
