为什么测试使用NUnit/TestDriven.Net2.0崩溃？

Question

我有一套运行良好的TestFixtures.我在夹具中添加了一个新的测试,但由于某种原因,我无法运行它.在其他类甚至同一类中的其他测试运行良好.

• NUnit GUI/TestDriven都崩溃了

如果我从NUnit GUI运行,我会收到此错误:

NUnit已停止使用此消息

在VS2008中使用TestDriven.Net 2.0,得到此错误:

Answer 1

好吧,你似乎很清楚你造成了堆栈溢出.StackOverflowException是一个致命的例外,它会降低CLR - 这就是你遇到这个问题的原因.

我建议您调试测试以找出堆栈溢出的原因.这通常是一个递归问题.例如,如果您在属性中输入错误:

 private readonly int age;

 public int Age
 {
     get { return Age; } // should be "return age;"
 }

这将导致堆栈溢出 - 但也可以不谨慎地编写递归方法.
