是的,现在有,我认为这两个问题和答案应该合并,在这里查看答案
Net Core: Execute All Dependency Injection in Xunit Test for AppService, Repository, etc
使用下面的自定义 Web 应用程序工厂和 ServiceProvider.GetRequiredService,随时编辑和优化答案
CustomWebApplicationFactory:
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:\\OriginalApplication";
configurationBuilder.AddJsonFile($"{path}\\appsettings.json", optional: true, reloadOnChange: true);
configurationBuilder.AddEnvironmentVariables();
});
// if you want to override Physical database with in-memory database
builder.ConfigureServices(services =>
{
var serviceProvider = new ServiceCollection()
.AddEntityFrameworkInMemoryDatabase()
.BuildServiceProvider();
services.AddDbContext<ApplicationDBContext>(options =>
{
options.UseInMemoryDatabase("DBInMemoryTest");
options.UseInternalServiceProvider(serviceProvider);
});
});
}
}
集成测试:
public class DepartmentAppServiceTest : IClassFixture<CustomWebApplicationFactory<OriginalApplication.Startup>>
{
public CustomWebApplicationFactory<OriginalApplication.Startup> _factory;
public DepartmentAppServiceTest(CustomWebApplicationFactory<OriginalApplication.Startup> factory)
{
_factory = factory;
_factory.CreateClient();
}
[Fact]
public async Task ValidateDepartmentAppService()
{
using (var scope = _factory.Server.Host.Services.CreateScope())
{
var departmentAppService = scope.ServiceProvider.GetRequiredService<IDepartmentAppService>();
var dbtest = scope.ServiceProvider.GetRequiredService<ApplicationDBContext>();
dbtest.Department.Add(new Department { DepartmentId = 2, DepartmentCode = "123", DepartmentName = "ABC" });
dbtest.SaveChanges();
var departmentDto = await departmentAppService.GetDepartmentById(2);
Assert.Equal("123", departmentDto.DepartmentCode);
}
}
}
