我正在fixture
上tests
。
在我的FixtureFactory
中,我制作了自己的ServiceCollection
:
private static ServiceCollection CreateServiceCollection()
{
var services = new ServiceCollection();
services.AddScoped<IConfiguration>();
services.AddScoped<ITokenService, TokenService>();
services.AddDbContext<TaskManagerDbContext>(o => o.UseInMemoryDatabase(Guid.NewGuid().ToString()));
services.AddIdentity<ApplicationUser, IdentityRole>(options =>
{
options.Password.RequiredLength = 6;
options.Password.RequireLowercase = false;
options.Password.RequireUppercase = false;
options.Password.RequireNonAlphanumeric = false;
options.Password.RequireDigit = false;
options.User.RequireUniqueEmail = true;
}).AddEntityFrameworkStores<TaskManagerDbContext>();
return services;
}
然后,我从services
获取此scope
:
var services = CreateServiceCollection().BuildServiceProvider().CreateScope();
var context = services.ServiceProvider.GetRequiredService<TaskManagerDbContext>();
var userManager = services.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();
var roleManager = services.ServiceProvider.GetRequiredService<RoleManager<IdentityRole>>();
var signInManager = services.ServiceProvider.GetRequiredService<SignInManager<ApplicationUser>>();
var tokenService = services.ServiceProvider.GetRequiredService<TokenService>();
当我将TokenService
添加到ServiceCollection
时,问题开始了。
TokenService
中的构造函数如下:
private readonly IConfiguration configuration;
private readonly UserManager<ApplicationUser> userManager;
public TokenService(IConfiguration configuration, UserManager<ApplicationUser> userManager)
{
this.configuration = configuration;
this.userManager = userManager;
}
启动我的Core
应用程序时效果很好,但不能从我上面提到的ServiceCollection
中使用。
在测试中,我开始出现此错误:
消息:System.AggregateException:发生一个或多个错误。 (无法实例化服务类型“ Microsoft.Extensions.Configuration.IConfiguration”的实现类型“ Microsoft.Extensions.Configuration.IConfiguration”。)(以下构造函数参数没有匹配的灯具数据:ServicesFixture灯具) ---- System.ArgumentException:无法实例化服务类型“ Microsoft.Extensions.Configuration.IConfiguration”的实现类型“ Microsoft.Extensions.Configuration.IConfiguration”。 ----以下构造函数参数没有匹配的夹具数据:ServicesFixture夹具
当我将services.AddScoped<IConfiguration>();
添加到ServiceCollection
并开始获得所需的服务TokenService
时,此错误开始显示。
我的问题是,如何在Configuration
中正确使用我正在使用的Service
?
我正在使用Configuration
从settings.json
获取物品。
编辑:
我的fixture
和示例测试类:
public class ServicesFixture
{
public TaskManagerDbContext Context { get; private set; }
public UserManager<ApplicationUser> UserManager { get; private set; }
public RoleManager<IdentityRole> RoleManager { get; private set; }
public SignInManager<ApplicationUser> SignInManager { get; private set; }
public TokenService TokenService { get; private set; }
public ServicesFixture()
{
var servicesModel = ServicesFactory.CreateProperServices();
this.Context = servicesModel.Context;
this.UserManager = servicesModel.UserManager;
this.RoleManager = servicesModel.RoleManager;
this.SignInManager = servicesModel.SignInManager;
this.TokenService = servicesModel.TokenService;
}
[CollectionDefinition("ServicesTestCollection")]
public class QueryCollection : ICollectionFixture<ServicesFixture>
{
}
}
测试:
[Collection("ServicesTestCollection")]
public class CreateProjectCommandTests
{
private readonly TaskManagerDbContext context;
public CreateProjectCommandTests(ServicesFixture fixture)
{
this.context = fixture.Context;
}
}
EDIT2
当我从集合中删除AddScoped<IConfiguration>();
并运行测试时,出现此错误:
消息:System.AggregateException:发生一个或多个错误。 (没有注册类型'TaskManager.Infrastructure.Implementations.TokenService'的服务。)(以下构造函数参数没有匹配的灯具数据:ServicesFixture灯具) ---- System.InvalidOperationException:没有注册类型为'TaskManager.Infrastructure.Implementations.TokenService'的服务。 ----以下构造函数参数没有匹配的夹具数据:ServicesFixture夹具
答案 0 :(得分:2)
您添加了IConfiguration
,但没有实现。
在 startup.cs 中,框架将在后台创建一个实现并将其添加。您将必须使用ConfigurationBuilder
var builder = new ConfigurationBuilder()
//.SetBasePath("path here") //<--You would need to set the path
.AddJsonFile("appsettings.json"); //or what ever file you have the settings
IConfiguration configuration = builder.Build();
services.AddScoped<IConfiguration>(_ => configuration);
//...
