我有一個應用程序當前按設計工作，但在擴展它之前，我嘗試使用 xUnit 設置集成測試。目前測試在執行測試時只會使用原始服務，我不明白為什么。這是測試：using IStoreRepository = Repositories.V3.Interfaces.IStoreRepository;public class StoreTests : IClassFixture<WebApplicationFactory<Startup>> {    private readonly ITestOutputHelper _output;    private readonly WebApplicationFactory<Startup> _factory;    private readonly string _url;    public StoreTests(ITestOutputHelper output, WebApplicationFactory<Startup> factory) {        _output = output;        _factory = factory;        _url = "/api/store";    }    [Theory]    [InlineData("GET", "FAKE123")]    public async Task StoreByCode(string method, string code = null) {        // var client = _factory.CreateClient();        var client = _factory.WithWebHostBuilder(builder => {            builder.ConfigureTestServices(services => {                services.AddScoped<IStoreRepository, StoreRepositoryTest>();            });        }).CreateClient();        var request = new HttpRequestMessage(new HttpMethod(method), $"{_url}/{code}");        string readAsStringAsync;        _output.WriteLine($"Request Uri: {request.RequestUri}");        using (var response = await client.SendAsync(request)) {            response.EnsureSuccessStatusCode();            readAsStringAsync = await response.Content.ReadAsStringAsync();            if (!response.IsSuccessStatusCode) {                _output.WriteLine($"Not successful ({response.StatusCode}): {readAsStringAsync}");            }        }        var stores = JsonConvert.DeserializeObject<List<Store>>(readAsStringAsync);        Assert.True(stores.Any());    }}Repository然而，當我進行測試時，實際中的斷點StoreRepository是在 Startup.cs 中注冊的，而不是 中的斷點StoreRepositoryTest。我設置我的工廠來覆蓋依賴項，但它忽略了它。我可以做什么來糾正這個問題。作為參考，我一直在使用此來源：https://learn.microsoft.com/en-us/aspnet/core/test/integration-tests ?view=aspnetcore-2.2
