Dataseeding not working when using WebApplicationFactory in integration test with nUnit - nunit

Question

I'm having problems with seeding my inmemory database with test-data in nUnit integration tests.
I've created a custom WebApplicationFactory so i could use an inmemory database:
public class SiriusWebApplicationFactory : WebApplicationFactory<Startup>
{
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
builder.ConfigureTestServices(services =>
{
var descriptor = services.SingleOrDefault(d => d.ServiceType == typeof(IAuthenticationSchemeProvider));
services.Remove(descriptor);
CleanupDatabaseRegistrations<SiriusContext>(services);
services.AddDbContext<SiriusContext>(options => options.UseInMemoryDatabase($"Testdb-{Guid.NewGuid()}"));
// Build the service provider.
var sp = services.BuildServiceProvider();
// Create a scope to obtain a reference to the database contexts
using var scope = sp.CreateScope();
var scopedServices = scope.ServiceProvider;
var context = scopedServices.GetRequiredService<SiriusContext>();
// Ensure the database is created.
context.Database.EnsureCreated();
});
}
private void CleanupDatabaseRegistrations<TDbContext>(IServiceCollection services) where TDbContext : DbContext
{
var descriptor = services.SingleOrDefault(d => d.ServiceType == typeof(DbContextOptions<TDbContext>));
if (descriptor != null)
{
services.Remove(descriptor);
}
descriptor = services.FirstOrDefault(d => d.ServiceType == typeof(DbContextOptions));
if (descriptor != null)
{
services.Remove(descriptor);
}
descriptor = services.SingleOrDefault(d => d.ServiceType == typeof(TDbContext));
if (descriptor != null)
{
services.Remove(descriptor);
}
}
}
After this, i've created a base class which is being used by all my integration test classes.
This base class implements the nUnit OneTimeSetup method where i create the HttpClient for testing my controllers:
protected HttpClient HttpClient;
protected SiriusContext DbContext;
[OneTimeSetUp]
public void OneTimeSetUp()
{
_webApplicationFactory = new SiriusWebApplicationFactory();
HttpClient = _webApplicationFactory.CreateClient();
DbContext = _webApplicationFactory.Services.GetService<SiriusContext>();
DoReseed();
}
As you can see i'm exposing my DbContext so that my test classes can seed the test data.
The DoReseed method is just an emppty method used by my integration test classes to provide test data.
protected virtual void DoReseed() { }
The implementation inside one of my testclasses looks like this:
public class AdminAanbestedingApplicatieControllerTests : BaseIntegrationTest
{
[Test]
public async Task AanbestedingApplicaties_GetAll_ShouldReturnData()
{
var result = await HttpClient.GetFromApi_AssertSuccess<List<AanbestedingApplicatie>>(RouteConstants.Lijsten.AdminAanbestedingApplicaties.GetAll);
Assert.IsTrue(result.Count > 1);
}
protected override void DoReseed()
{
DbContext.AanbestedingApplicaties.Add(AanbestedingApplicatiesObjectMother.AanbestedingApplicatie_Actief);
DbContext.AanbestedingApplicaties.Add(AanbestedingApplicatiesObjectMother.AanbestedingApplicatie_InActief);
DbContext.AanbestedingApplicaties.Add(AanbestedingApplicatiesObjectMother.AanbestedingApplicatie_ToDelete);
DbContext.AanbestedingApplicaties.Add(AanbestedingApplicatiesObjectMother.AanbestedingApplicatie_ToUpdate);
DbContext.SaveChanges();
}
}
When i execute my test, the seeding gets executed but the repository cannot see the seeded data?
The DbContext inside my repo does not contain my seeded data...
Anyone has any idea why the DbContext inside my repository does not contain the seeded test data?
The repo looks like this:
public IEnumerable<AanbestedingApplicatie> GetAll()
{
return SiriusContext.AanbestedingApplicaties.OrderBy(l => l.Naam).ProjectTo<AanbestedingApplicatie>(Mapper.ConfigurationProvider)
.ToList();
}
The Context has been injected inside the constructor...
