模拟单元测试并发C＃

Question

我的控制器中确实有一些功能。下面的代码是示例：

[HttpPost]
    public async Task<IActionResult> NewAccount(Account account)
    {
        if (ModelState.IsValid)
        {
            _Iaccount.NewAccount(account);
            return RedirectToAction("Accounts");
        }
        return View();
    }

我只想为此函数创建并发模拟单元测试。我试图创建一个。

    [TestMethod]
    public async Task TestforNewAccount()
    {
        Mock<IAccount> mock = new Mock<IAccount>();
        var testController = new AccountController(mock.Object);
        Account _account = new Account()
        {
            AccountName = "sample",
            Id = 1,
            AccountNumber = "123",
            Password = "sample"
        };
        mock.Setup(s => s.GetAccountById(1)).Returns(_account);
        IActionResult result = await testController.NewAccount(_account);
        Assert.IsInstanceOfType(result, typeof(RedirectToActionResult));
    }

    public async Task TestForConcurrentNewAccount()
    {
        await TestforNewAccount();
    }

但我认为它不会测试并发性。

谢谢！
