推荐答案

我们使用C＃动态的关键字与TDD。

We use the C# "dynamic" keyword with TDD.

这code没有编译，因为该方法加法不落实

This code doesn't compile because the method "Addition" is not implemented

[TestMethod()]
public void CalculatorThingAdd_2PositiveNumbers_ResultAdded()
{
    CalculatorThing myCalculator = new CalculatorThing();
    int result = 0; 
    int expcected = 3;

    // --> CalculatorThing  does not contain a definition for 'Addition'
    result = myCalculator.Addition(1, 2);

    Assert.AreEqual(result, expcected);
}

通过动态关键字的code编译和测试失败！ - > TDD

With the "dynamic" keyword the code compiles and the test fails! --> TDD
