具有Result属性的Nunit TestCase属性工作不正确吗? [英] Does Nunit TestCase attribute with Result property work incorrect?

问题描述

因此，我为Nunit 2.6(使用2.6.0.12035版本)编写了下一个测试"测试:-)

So, I wrote next "test" test :-) for Nunit 2.6 (use 2.6.0.12035 ver.)

    [TestCase(1, 2, Result = 3)]
    [TestCase(3, 4, Result = 7)]
    [TestCase(5, 6, Result = 11)]
    public int Add_Test(int a, int b)
    {
        return a - b;
    }

接下来，我使用Resharper 6.1.37.86运行它. Resharper显示所有三个测试均通过. 比我尝试使用nunit GUI-nunit.exe运行测试.测试失败，并显示奇怪的错误消息:方法具有非空返回值". 实际上，所有测试都将失败，并带有意外的结果值. 这个功能工作不正确还是我做不到?错误的? 顺便说一句，接下来，我尝试不设置Result属性，它对两个跑步者都适用:

Next, I run it with Resharper 6.1.37.86. Resharper shows that all three test are passed. Than I try to run test with nunit GUI - nunit.exe. Tests fall with strange error message: "Method has non-void return value". In fact all tests should fail with unexpected value of result. Does this feature work incorrect or I do smth. wrong? By the way, next I try do without set Result property and it works perfect with both runners:

    [TestCase(1, 2, 3)]
    [TestCase(3, 4, 7)]
    [TestCase(5, 6, 11)]
    public void Add_Test1(int a, int b, int result)
    {
        Assert.AreEqual(result, a - b);
    }

推荐答案

无论我使用NUnit.exe还是NUnit-console.exe，我在NUnit 2.6.0.12035中都遇到相同的问题.

I get the same problem with NUnit 2.6.0.12035, whether I use NUnit.exe or NUnit-console.exe.

您的示例可以使用NUnit.exe 2.5.10正常运行. (我的猜测是Resharper使用的是NUnit 2.5.10，因此测试通过了.)

Your example works fine using NUnit.exe 2.5.10. (My guess is that Resharper is using NUnit 2.5.10 and so the test passes.)

我已报告该问题到NUnit论坛.

编辑:我的测试程序集引用了 NUnit.framework.dll 的2.5.10版本.如果我切换为使用2.6.0.12035版本，则该测试将同时对 NUnit.exe 和 NUnit-console.exe 正常运行.我敢打赌，你的问题是一样的.

My test assembly was referencing the 2.5.10 version of NUnit.framework.dll. If I switch to use the 2.6.0.12035 version, the test works as expected with both NUnit.exe and NUnit-console.exe. I'll bet your issue is the same.

它已作为错误提交，并已已修复在下一个版本中.如果您的单元测试库链接到旧版本的 Nunit.framework.dll ，则2.6中的测试运行程序将不再导致错误.

Edit 2: It has been submitted as a bug and fixed in the next release. The test runners in 2.6 will no longer cause an error if your unit test library links to an older version of Nunit.framework.dll.
