c# - 使用 [ClassInitilize]Attribute 相对于静态构造函数(或 : TestContext wat? !)的优势

Question

---

我没有得到 [ClassInitilize] 属性的好处。

---

示例代码

[TestClass]
public class MyTestClass
{
    static MyTestClass()
    {
        //startup logic
    }

    [ClassInitialize]
    public static void Initilize(TestContext context)
    {
        //startup logic
    }
}

问题

在静态构造函数上使用 [ClassInitilize] 是否有任何实际用法？
我的意思是我在 Initilize() 方法中得到了一个 TestContext 对象，但我真的看不到它有任何用处。

简而言之:
为什么需要 TestContext。

来自 MSDN: Using the TestContext Class :

You use the TestContext class in unit tests for any of several purposes. These are its most frequent uses:

• In any unit test, because the TestContext class stores information that is provided to unit tests, such as the path to the deployment directory. For more information, see Structure of Unit Tests.

• In unit tests to test Web services that run on ASP.NET Development Server. In this case, TestContext stores the URL of the Web service. For more information, see Testing Web Services.

• In ASP.NET unit tests, to obtain access to the Page object. For more information, see Working with ASP.NET Unit Tests.

• In data-driven unit tests, the TestContext class is required because it provides access to the data row. For more information, see Working with Data-Driven Unit Tests, Coding a Data-Driven Unit Test, and Walkthrough: Using a Configuration File to Define a Data Source.
