如何在Unit Test类的[ClassInitialize()]中编写输出？

[TestClass]
public class MyTestClass
{
    private static TestContext testContext;

    [ClassInitialize()]
    public static void MyClassInitialize(TestContext testContext)
    {
        MyTestClass.testContext = testContext;
    }

    // ...
}

[TestClass]
public class MyTestClass
{
    private static TestContext testContext;

    [ClassInitialize()]
    public static void MyClassInitialize(TestContext testContext)
    {
        MyTestClass.testContext = testContext;
        MyTestClass.testContext.WriteLine("This is a sample output from ClassInitialize().");
    }

    // ...
}
