Question

我创建的测试看起来像这样：

[Test]
public async Task MemberCannotCreateConfirmedUser()
{
    var services = UserContext.GivenServices();
    await services.LoginAsync(new Claim("User", "Member"));
    Assert.That(await services.WhenCreateUserAsync("AAAB", "AAAB", "AAAB", "FIN", emailConfirmed: true), Throws.TypeOf<ArgumentException>());
}

实际抛出错误的代码如下所示：

var principal = _httpContext.User as ClaimsPrincipal;
var isAdmin = principal?.FindFirst("Administrator") != null;
if (!isAdmin)
{
    if (model.EmailConfirmed) throw new ArgumentException("Only an administrator can confirm a new user");
}

当我运行测试时，它失败并说明：

System.ArgumentException：只有管理员才能确认新用户

但这肯定是我正在测试的。它应该通过，因为它会引发ArgumentException错误？

原来我只是做错了断言。因为委托是异步的，所以我需要进行异步检查。所以用这个替换我的Assert：

Assert.ThrowsAsync<ArgumentException>(async () => await services.WhenCreateUserAsync("AAAB", "AAAB", "AAAB", "FIN", emailConfirmed: true));
