How to start GraphQL server when running .net5 integration tests? - graphql

Question

I believe I am missing/misunderstanding something fundamental about the way .net5 works. In setting up an integration test environment for my GraphQL API, I am missing the step on how to start the GraphQL server from said test environment.
When I run the main project, the server is started properly and I can navigate to localhost in the browser and successfully execute GraphQL queries/mutations. My goal here is to set up some automated integration tests.
I'm using NUnit as my test runner and am using WebApplicationFactory<Startup> to "start the server" as I understand it.
In my test project, I'm under the impression that WebApplicationFactory<Startup> is supposed to basically use the Startup.cs class from my main project in my test project so that I don't have to duplicate all the settings, configurations, and injected services. Please correct me if that assumption is not correct.
I've pasted the code I think is relevant.
ApiWebApplicationFactory<Startup>
public class ApiWebApplicationFactory<TStartup> : WebApplicationFactory<Startup> where TStartup : class
{
public static IConfigurationRoot Configuration { get; set; }
public ApiWebApplicationFactory()
{
var configBuilder = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
Configuration = configBuilder.Build();
}
protected override void ConfigureClient(HttpClient client)
{
base.ConfigureClient(client);
client.BaseAddress = new Uri("https://localhost");
client.Timeout = new TimeSpan(0, 10, 0);
}
// Based on my assumption this class reuses everything in the Startup.cs class
// I don't actually think this is necessary, but thought it was worth trying
// the test with and without this code.
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
builder.ConfigureServices(services =>
{
services
.AddGraphQLServer()
.AddQueryType<Query>()
.AddMutationType<Mutation>()
.AddType<GraphQLContentItem>()
.AddType<GraphQLFolder>();
});
}
}

[OneTimeSetUp]
public void OneTimeSetUp()
{
_factory = new ApiWebApplicationFactory<Startup>();
_client = _factory.WithWebHostBuilder(builder =>
{
builder.ConfigureServices(services =>
{
services.AddScoped<ICacheRepository, MockCache>();
});
}).CreateClient();
var connString = ApiWebApplicationFactory<Startup>.Configuration.GetConnectionString("DefaultConnection");
var options = new DbContextOptionsBuilder<CmsContext>()
.UseMySql(connString, ServerVersion.AutoDetect(connString))
.Options;
_dbContext = new CmsContext(options);
_dbContext.Database.EnsureCreated();
}
Test
[Test]
public async Task Test()
{
// If I set a breakpoint here, I can't navigate to the URL like I'm expecting to
var graphQLHttpClient =
new GraphQLHttpClient(
new GraphQLHttpClientOptions { EndPoint = new Uri("https://localhost/graphql") },
new NewtonsoftJsonSerializer(),
_client);
var request = new GraphQLRequest
{
Query = #"
query GetCurrentSession() {
getCurrentSession() {
id
name
}
}",
OperationName = "GetCurrentSession"
};
// Error is thrown here with "Bad Request"
var response = await graphQLHttpClient.SendQueryAsync<Session>(request);
// Further code is omitted
}
Please let me know if you see what I am missing. Thanks in advance~
