我正在将现有的ASP.NET 5 Web应用程序迁移到ASP.NET 6,并遇到了通过集成测试的最后障碍。
我自定义了WebApplicationFactory,但它抛出了异常:Changing the host configuration using WebApplicationBuilder.WebHost is not supported. Use WebApplication.CreateBuilder(WebApplicationOptions) instead.
public class CustomWebApplicationFactory<TStartup> : WebApplicationFactory<TStartup> where TStartup : class
{
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
Environment.SetEnvironmentVariable("ASPNETCORE_ENVIRONMENT", "IntegrationTests");
builder.ConfigureServices(services => {
// Create a new service provider.
var serviceProvider = new ServiceCollection()
.AddEntityFrameworkInMemoryDatabase().AddLogging()
.BuildServiceProvider();
// Add a database context (AppDbContext) using an in-memory database for testing.
services.AddDbContextPool<AppDbContext>(options =>
{
options.UseInMemoryDatabase("InMemoryAppDb");
options.UseInternalServiceProvider(serviceProvider);
options.EnableSensitiveDataLogging();
options.EnableDetailedErrors();
options.LogTo(Console.WriteLine);
});
services.AddDbContextPool<AppIdentityDbContext>(options =>
{
options.UseInMemoryDatabase("InMemoryIdentityDb");
options.UseInternalServiceProvider(serviceProvider);
options.EnableSensitiveDataLogging();
options.EnableDetailedErrors();
options.LogTo(Console.WriteLine);
});
services.AddScoped<SignInManager<AppUser>>();
services.AddScoped<ILogger<UserRepository>>(provider => {
ILoggerFactory loggerFactory = provider.GetRequiredService<ILoggerFactory>();
return loggerFactory.CreateLogger<UserRepository>();
});
services.AddDistributedMemoryCache();
// 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 appDb = scopedServices.GetRequiredService<AppDbContext>();
var identityDb = scopedServices.GetRequiredService<AppIdentityDbContext>();
var logger = scopedServices.GetRequiredService<ILogger<CustomWebApplicationFactory<TStartup>>>();
// Ensure the database is created.
appDb.Database.EnsureCreated();
identityDb.Database.EnsureCreated();
try
{
// Seed the database with test data.
SeedData.PopulateTestData(identityDb);
SeedData.PopulateTestData(appDb);
}
catch (Exception ex)
{
logger.LogError(ex, $"An error occurred seeding the " +
$"database with test messages. Error: {ex.Message}");
}
}
});
}
}
例外情况:
Message:
System.NotSupportedException : The content root changed from "C:\Projects\C#\AspNetCoreApi\src\Web.Api\" to "C:\Projects\C#\AspNetCoreApi\test\Web.Api.IntegrationTests\bin\Debug\net6.0\".

任何建议和见解都将受到赞赏。

由于Program.cs中的这一行而发生错误:
我添加这个是因为我想保留
args
,所以我使用了WebApplication.CreateBuilder(args)
。感谢@davidfowl,我使用了下面的代码片段:并删除了出错的代码行。请注意,只要输入参数与默认值不同,
builder.WebHost.UseContentRoot
就会抛出异常。在我的示例中,只要运行集成测试,它就会抛出异常,但正常运行应用程序时不会。7gcisfzg2#
当我尝试将API创建为窗口服务时,我遇到了同样的问题,
我用下面的代码解决了

当我将API迁移到.NET6时,我在集成测试中遇到了同样的问题。
我通过在我的自定义
WebApplicationFactory
中添加builder.UseContentRoot(".")
解决了这个问题。完整代码:
