NUnit测试Stylecop自定义规则 [英] NUnit Testing Stylecop custom rules

问题描述

我目前正在从事单元测试，Stylecop自定义规则的工作，我试图使用NUnit V2.6对我的Stylecop规则进行测试，但是我尝试了很多时间将Stylecop实体转换为字符串，但这是行不通的.以下是我尝试使用的示例代码

Hi,

I am currently working on Unit Testing, Stylecop custom rules, i tried to use NUnit V2.6 to test on my Stylecop rules, but i tried lots of time to convert Stylecop entity to string it doesn''t work. below is the example code i was trying to work on

[TestFixture]
public class MyCalPath
{

    public static void main(string[] args)
    {
        string projectPath = @"C:\Documents and Settings\NickyPhun\My Documents\Visual Studio 2010\Projects\MyCustomRules3\MyCustomRules3";
        string filePath = @"C:\Documents and Settings\NickyPhun\My Documents\Visual Studio 2010\Projects\MyCustomRules3\MyCustomRules3\MyCal.cs";
        StyleCopConsole console = new StyleCopConsole(null, false, null, null, true);
        CodeProject project = new CodeProject(0, projectPath, new Configuration(null));
        console.Core.Environment.AddSourceCode(project, filePath, null);
        console.OutputGenerated += OnOutputGenerated;
        console.ViolationEncountered += OnViolationEncountered;
        console.Start(new[] { project }, true);
        console.OutputGenerated -= OnOutputGenerated;
        console.ViolationEncountered -= OnViolationEncountered;

    }
    [Test]
    public static void OnOutputGenerated(object sender,OutputEventArgs e)
    {
        Console.WriteLine(e.Output);
    }
    [Test]
    public static void OnViolationEncountered(object sender, ViolationEventArgs e)
    {
        Console.WriteLine("{0}: {1}", e.Violation.Rule.CheckId, e.Message);
    }

正如我试图在NUnit中打印错误消息一样，但这是因为像NUnit测试一样，它并不能容纳任何对象和Stylecop元素.寻求有关如何将OutputEventArgs转换为String并将其在NUnit Testing平台中打印出来的建议

谢谢

as i was trying to print out the error messagein NUnit, but it since like NUnit testing doesn''t acceot any object and Stylecop element. seeking advice on how i able to conver OutputEventArgs to String and print it out in NUnit Testing platform

Thank you

Extract from Clean Coders StyleCop Rules

Your cast seems bad. You are looking at a syntax similar to this:

this.StyleCopConsole.ViolationEncountered += (sender, args) => this.StyleCopViolations.Add(args.Violation);
