c# - 如何在单元测试项目中运行测试（当方法有参数时）

Question

我有一个单元测试，我想在其中命名参数，例如：

[TestMethod]
public void Register(bool DoSeed = false, AccountViewModelForReg VM = null)
{
    AutoMapperConfig.Configure(); //TODO move to global

    AccountController C = new AccountController();
    VM = new AccountViewModelForReg()
    {
        Username = "testuser1",
        Password = AccountHelper.HashPassword("a"),
        Email = "testuser1"+CommonEmailSuffix,
        Email2 = "testuser1"+CommonEmailSuffix
    };
    var Result = C.Register(VM, true) as ViewResult;
    Assert.AreEqual("Register", Result.ViewName);
}

这就是我的 EF Seeder 的情况，我可以使用我的单元测试来播种，只需传入参数。但由于该方法需要参数，Visual Studio 不会将其视为要运行的测试。我怎样才能解决这个问题？

Answer 1

AFAIK, VS unit test don't support parameterized unit tests.
Your only way is to write another, parameterless overload and call your method from there. BTW: The optional parameters are nothing but syntactical sugar; the method still requires the parameters.

Example:

public void Test_One(bool p1, string p2)
//...
public void Test_One()
{
   Test_One(true, "defaultvalue");
}

You should take a look at another framework, e.g. NUnit, which allows you to easily parametrize your tests (even with ranges, automatic combination of parameters etc.): See http://nunit.org/index.php?p=parameterizedTests&r=2.5

您可以扩展 MSTest 以允许这样做。
