DataTestMethod and DataRow attributes in MSTEST
提问by Simon Vane
I have seen in a Microsoft video about Visual Studio update 2 regarding these attributes. However, I can't find any other information about them and can't get a project to build with them.
我在有关这些属性的 Visual Studio 更新 2 的 Microsoft 视频中看到过。但是，我找不到有关它们的任何其他信息，也无法使用它们构建项目。
Does anyone know anything about these attributes or how to get them working?
有没有人知道这些属性或如何让它们工作？
[DataTestMethod]
[DataRow("a", "b")]
[DataRow(" ", "a")]
public void TestMethod1(string value1, string value2)
{
Assert.AreEqual(value1 + value2, string.Concat(value1, value2));
}

I know this is an old question, but there is now a good walkthrough published at https://blogs.msmvps.com/bsonnino/2017/03/18/parametrized-tests-with-ms-test/
我知道这是一个老问题，但现在有一个很好的演练发布在https://blogs.msmvps.com/bsonnino/2017/03/18/parametrized-tests-with-ms-test/
In a nutshell, you will need to install MSTest.TestFrameworkand MSTest.TestAdapter, and remove references to Microsoft.VisualStudio.QualityTools.UnitTestFramework. You can then indicate a parameterised test with the [DataTestMethod]attribute, and can add your parameters using the [DataRow]attribute, as per your example. The values from the [DataRow]attribute will be passed to the test method in the order in which they are specified.
简而言之，您需要安装MSTest.TestFramework和MSTest.TestAdapter，并删除对Microsoft.VisualStudio.QualityTools.UnitTestFramework. 然后，您可以使用该[DataTestMethod]属性指示参数化测试，并可以[DataRow]根据您的示例使用该属性添加参数。[DataRow]属性中的值将按照指定的顺序传递给测试方法。
Note that the values in the [DataRow]attribute must be primitives, so you can't use a DateTimeor decimalfor example. If you want them, you will have to work around this limitation (e.g. instead of having a DateTimeparameter to represent a date, you could have three integer parameters representing year, month and day, and create the DateTimewithin the test body).
请注意，[DataRow]属性中的值必须是基元，因此不能使用 aDateTime或decimal例如。如果你想要它们，你将不得不解决这个限制（例如DateTime，你可以用三个整数参数来表示年、月和日，而不是用一个参数来表示日期，并DateTime在测试主体内创建）。

It appears this is only available within the unit testing project for WinRT/Metro and now with update 2, Windows Phone 8. It's a mystery to my why this is not available for all testing with mstest.
看来这仅在 WinRT/Metro 的单元测试项目中可用，现在在更新 2、Windows Phone 8 中可用。为什么这不适用于 mstest 的所有测试，这对我来说是个谜。

Finally, this feature has been added (still in pre-release) https://blogs.msdn.microsoft.com/visualstudioalm/2016/06/17/taking-the-mstest-framework-forward-with-mstest-v2/
最后，此功能已添加（仍在预发布中） https://blogs.msdn.microsoft.com/visualstudioalm/2016/06/17/taking-the-mstest-framework-forward-with-mstest-v2/
Basically, one has to do two things:
基本上，一个人必须做两件事：
1) Install two NuGet packages (versions don't really matter, but this is what I have)
1）安装两个 NuGet 包（版本并不重要，但这是我所拥有的）
<package id="MSTest.TestAdapter" version="1.1.5-preview" targetFramework="net452" />
<package id="MSTest.TestFramework" version="1.0.6-preview" targetFramework="net452" />
2) Remove the refenrece to the old test library, because it has the same attributes defined in the same namespaces - this was done to achieve backwards compatibility
2) 删除对旧测试库的引用，因为它在相同的命名空间中定义了相同的属性 - 这样做是为了实现向后兼容性
Microsoft.VisualStudio.QualityTools.UnitTestFramework
