获取所有测试方法名称 [英] Getting All Test Methodes Names

问题描述

如何在包含许多项目的整个解决方案中获取所有测试方法名称

意味着我想以编程方式从解决方案层次中提取测试方法名称

how can i get all test methods names in an entire solution having many projects
meaning i want to extract test methods names from solution hierarchy programmatically

推荐答案

首先，您需要定义用于区分测试方法与其他方法的标准。



如果您使用的是特殊工具/用于测试的库，如NUnit或VisualStudio.TestTools.UnitTesting，那么这可能相对容易;如果你已经创建了自己的测试库，那么你可能会创建一个自定义属性来装饰测试方法。



如果你使用的话没有提供轻松获取所有方法的方法......我认为这就是这种情况......你将选择.dll或.dll，并使用递归递归搜索符合条件的方法。



递归搜索会有这种流：

First of all, you need to define the criteria by which you will distinguish test methods from other methods.

If you are using a special tool/library for testing, like NUnit, or VisualStudio.TestTools.UnitTesting, then this may be relatively easy; if you have created your own testing library, then you would probably create a Custom Attribute to adorn test methods with.

In the case whatever you use doesn't provide a way to get at all the methods easily ... I assume that's the case here ... you are going to select a .dll, or .dll's, and search recursively, using recursion, for Methods that meet your criteria.

A recursive search is going to have this kind of "flow:"

// this is pseudo-code:
foreach FileInfo theFileInfo in AWholeBunchOfDLLFiles

Assembly theAssembly = Assembly.LoadFrom(theFileInfo.FullName);

foreach Type theType in theAssembly.GetTypes()
foreach MethodInfo theMethod in theType.GetMethods()
foreach Attribute attr in Attribute.GetCustomAttributes(theMethod)

// this is an example from working code:
if (attr.GetType() == typeof (YourTestMethodAttribute))
{
    // Bingo !

    YourTestMethodAttribute mta = attr as MyTestMethodAttribute;

    Console.WriteLine
    (
        "Method {0} with MyTestMethodAttribute ID: {1}",
        mInfo.Name,
        mta.ID
    );
}

这是一个实际自定义属性的示例，可以使用上面显示的代码：

This is an example of an actual Custom Attribute that would work with the code shown above:

public class YourTestMethodAttribute : Attribute
{
    private static int _id;

    protected int ID
    {
        set { _id = value; }
        get { return _id; }
    }

    public YourTestMethodAttribute()
    {
        ID++;
    }
}
