单元测试代码如何与内部异常?
作者:互联网
我想对以下代码进行一些单元测试:
public static class ExceptionExtensions {
public static IEnumerable<Exception> SelfAndAllInnerExceptions(
this Exception e) {
yield return e;
while (e.InnerException != null) {
e = e.InnerException; //5
yield return e; //6
}
}
}
编辑:看来我不需要Moles来测试此代码.另外,我有一个错误,第5行和第6行颠倒了.
解决方法:
这就是我得到的(毕竟不需要摩尔):
[TestFixture]
public class GivenException
{
Exception _innerException, _outerException;
[SetUp]
public void Setup()
{
_innerException = new Exception("inner");
_outerException = new Exception("outer", _innerException);
}
[Test]
public void WhenNoInnerExceptions()
{
Assert.That(_innerException.SelfAndAllInnerExceptions().Count(), Is.EqualTo(1));
}
[Test]
public void WhenOneInnerException()
{
Assert.That(_outerException.SelfAndAllInnerExceptions().Count(), Is.EqualTo(2));
}
[Test]
public void WhenOneInnerException_CheckComposition()
{
var exceptions = _outerException.SelfAndAllInnerExceptions().ToList();
Assert.That(exceptions[0].InnerException.Message, Is.EqualTo(exceptions[1].Message));
}
}
