我在控制器上有一个动作,它调用

var result = await HttpContext.AuthenticateAsync(IdentityServerConstants.ExternalCookieAuthenticationScheme);

我试图在这样的单元测试中模拟这个结果

httpContextMock.AuthenticateAsync(Arg.Any<string>()).Returns(AuthenticateResult.Success(...

然而,这带来了一个 InvalidOperationException

“尚未注册“Microsoft.AspNetCore.Authentication.IAAuthenticationService”类型的服务”

模仿这种方法的正确方法是什么?

那个 extension method

/// <summary>
/// Extension method for authenticate.
/// </summary>
/// <param name="context">The <see cref="HttpContext"/> context.</param>
/// <param name="scheme">The name of the authentication scheme.</param>
/// <returns>The <see cref="AuthenticateResult"/>.</returns>
public static Task<AuthenticateResult> AuthenticateAsync(this HttpContext context, string scheme) =>
    context.RequestServices.GetRequiredService<IAuthenticationService>().AuthenticateAsync(context, scheme);

通过 IServiceProvider RequestServices 所有物

/// <summary>
/// Gets or sets the <see cref="IServiceProvider"/> that provides access to the request's service container.
/// </summary>
public abstract IServiceProvider RequestServices { get; set; }

模拟服务提供商以返回模拟的 IAuthenticationService 你应该能够通过考试假装通过考试。

authServiceMock.AuthenticateAsync(Arg.Any<HttpContext>(), Arg.Any<string>())
    .Returns(Task.FromResult(AuthenticateResult.Success()));
providerMock.GetService(typeof(IAuthenticationService))
    .Returns(authServiceMock);
httpContextMock.RequestServices.Returns(providerMock);
