Nunit ExpectedException 是否正常工作? [英] Is Nunit ExpectedException Working Correctly?

问题描述

在设置一些命令行脚本来测试我正在处理的项目的 NUnit 测试套件时，我早些时候开始遇到问题.

我注意到在 Visual Studio 或 Xamarin 中运行测试时，结果是我所期望的，但是当使用 nunit 从命令行运行时-console (mac v2.4.8) 它不会通过某些测试.

所有在控制台中失败的测试都使用 [ExpectedException] 属性(包括类型和一般).当改为使用 Assert.Throws<> 时，它在 IDE 和命令行中都能正常工作.

这是 Nunit 或我拥有的特定版本/平台的错误吗?

解决方案

这是 unit-console 2.4.8 中的一个错误，与一位评论者建议的 VS 测试运行程序无关.我在 cmd-line 上使用 3.x 来解决它，方法是在我将它添加到我的 Makefile 中时执行本地 nuget 安装，并且可以执行make test".

通过 2.4.8 进行测试(并暴露错误/问题):

测试用例:

使用NUnit.Framework;使用系统；命名空间除外{[测试夹具()]公开课测试{[测试 ()][预期异常]公共无效预期异常(){抛出新异常(Stackoverflow")；}[测试 ()][ExpectedException("System.DivideByZeroException")]public void ExpectedNotSystemException(){抛出新异常(Stackoverflow")；}[测试 ()][ExpectedException(typeof(DivideByZeroException))]public void ExpectedNotTypeOfSystemException (){抛出新异常(Stackoverflow")；}[测试 ()]public void NotExpectedException(){抛出新异常(Stackoverflow")；}}}

I started having problems earlier when setting up some command line scripts to test my NUnit suite of tests for a project I am working on.

I noticed that when running the tests in Visual Studio or Xamarin that the results are what I expected, but when running from the command line with the nunit-console (mac v2.4.8) it doesn't fail some of the tests.

All the of the tests that are failing that don't fail in the console use the [ExpectedException] attribute (both with a type and in general). When changing to use Assert.Throws<> it works correctly in both the IDEs and the command line.

Is this a bug with Nunit or the particular version/platform I have?

解决方案

It is a bug in unit-console 2.4.8 and has nothing to due with VS test runner as one commenter suggested. I use 3.x on the cmd-line to work around it by doing a local nuget install as I add this into my Makefile and can do a 'make test'.

Testing via 2.4.8 (and exposing the bug/issue):

nunit-console -nologo -labels except.dll

***** except.Test.ExpectedException
***** except.Test.ExpectedNotSystemException
***** except.Test.ExpectedNotTypeOfSystemException
***** except.Test.NotExpectedException
