c# nunit 异常集成测试

Question

我创建了一个如下所示的测试：

[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，它失败并显示：

System.ArgumentException : Only an administrator can confirm a new user

但这肯定是我要测试的。它应该通过，因为它抛出 ArgumentException 错误？

Answer 1

原来我只是在断言错误。因为委托是异步的，所以我需要做一个异步检查。所以用这个替换我的断言：

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