Question

如何从CustomWebApplicationFactory获取所有服务？启动类对IDepartmentRepository和IDepartmentAppService进行了依赖项注入。想获取新的DI存储库或服务。

我们正在创建指向原始应用程序启动的集成测试。

namespace Integrationtest
{
    public class CustomWebApplicationFactory<TStartup> : WebApplicationFactory<TStartup> where TStartup : class
    {
        protected override void ConfigureWebHost(IWebHostBuilder builder)
        {
            builder.ConfigureAppConfiguration((hostingContext, configurationBuilder) =>
            {
                var type = typeof(TStartup);
                var path = @"C:\\OriginalApplicationWebAPI";

                configurationBuilder.AddJsonFile($"{path}\\appsettings.json", optional: true, reloadOnChange: true);
                configurationBuilder.AddEnvironmentVariables();
            });
        }
    }
}

public class DepartmentAppServiceTest : IClassFixture<CustomWebApplicationFactory<OriginalApplication.Startup>>

{
    public testDbContext context;
    private readonly HttpClient _client;

    public DepartmentAppServiceTest(CustomWebApplicationFactory<OriginalApplication.Startup> factory)
    {
        _client = factory.CreateClient();
        factory.  // trying to find services here for IDepartmentRepository 
    }

Answer 1

它是factory.Host.Services。不要忘记，您将需要创建一个范围来访问范围化服务，例如您的上下文：

using (var scope = _factory.Host.Services.CreateScope())
{
    var foo = scope.ServiceProvider.GetRequiredService<Foo>();
    // do something
}

Answer 2

收到的错误：

'CustomWebApplicationFactory'不包含'Host'的定义，找不到可以接受的扩展方法'Host'接受类型为'CustomWebApplicationFactory'的第一个参数（您是否缺少using指令或程序集引用？）

因此，我必须将其与添加的服务器一起使用，如下所示：

using (var scope = _factory.Server.Host.Services.CreateScope())
{
    // do something
}
