Net Core Identity 不使用 InMemory 数据库

如何解决Net Core Identity 不使用 InMemory 数据库

我正在为我的应用进行集成测试。我想在我的测试中使用 InMemory 数据库，所以我创建了 IntegrationTest 类，在那里我用我的 Web API 设置了我的 HttpClient：

public class IntegrationTest
{
    protected readonly HttpClient TestClient;
    protected Integrationtest()
    {
        Environment.SetEnvironmentvariable("ASPNETCORE_ENVIRONMENT","Staging");
        Environment.CurrentDirectory = "C:\\Users\\adamg\\source\\repos\\CarShowroomApp\\CarShowroomBackEnd\\CarShowroomApp.UI\\";
        var appFactory = new WebApplicationFactory<Startup>()
            .WithWebHostBuilder(builder =>
            {
                builder.ConfigureServices(services =>
                {
                    services.RemoveAll(typeof(DatabaseContext<User,Role>));

                    services.AddDbContext<DatabaseContext<User,Role>>(options =>
                        options.UseInMemoryDatabase("xxx")
                    );
                    services.AddIdentity<User,Role>()
                        .AddRoles<Role>()
                        .AddEntityFrameworkStores<DatabaseContext<User,Role>>();
                });
            });

        TestClient = appFactory.CreateClient();
    }

    protected async Task AuthenticateAsync()
    {
        TestClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("bearer",await GetJwtAsync());
    }

    private async Task<string> GetJwtAsync()
    {
        var response = await TestClient.PostAsJsonAsync("api/auth/login",new UserForRegisterDto()
        {
            UserName = "TestUser123",Password = "#Mastercard1"
        });

        return (await response.Content.ReadAsAsync<AuthSuccessResponse>()).Token.ToString();
    }
}

构建整个应用程序后，我从服务提供程序中删除了 DbContext (EF Core)，并使用 InMemory Db 添加了新的。然后我添加身份（感谢“暂存”环境 - 构建时没有添加身份）。 尽管有这些操作，API 在测试期间仍然使用生产数据库：

public class CarControllerIntegrationTest : IntegrationTest
{
    [Fact]
    public async Task GetAllAsync_NoCars_OkObjectResultWithEmptyList()
    {
        await AuthenticateAsync();

        var response = await TestClient.GetAsync("api/car/");

        response.StatusCode.Should().Be(HttpStatusCode.OK);
        (await response.Content.ReadAsAsync<PagedList<CarDto>>()).Should().BeEmpty();
    }
}
