Extract test cases from visual studio 2013

Question

How to extract all classes with "TestClass" attribute and all its methods with "TestMethods" attributes into an external file like .txt or excel types without using TFS?

you mean by clicking some sort of menu item or by executing self written code? — nozzleman, Aug 11 '14 at 10:01
I don't understand why down vote. It is a valid question, I want to extract all Test classes and its test methods. What's up with it? — Mikk, Aug 11 '14 at 10:05
That's the thing, I don't know where to even start. I did some googling but couldn't find anything. You know where there's no effort? Judging someone by downvoting a question when it is valid and assuming the person asking didn't do any effort. — Mikk, Aug 11 '14 at 10:09

extract test cases in visual studio 2013, export test explorer vs2013 certainly didn't give anything for me — Mikk, Aug 11 '14 at 10:20

There are probably tools but here is a simple implementation using reflection:

var assembly = Assembly.LoadFile("xxx.dll");

var testClasses = assembly.GetTypes()
    .Where(c => c.GetCustomAttribute<TestClassAttribute>() != null);

foreach (var testClass in testClasses)
{
    Console.WriteLine("Found test class " + testClass.FullName);

    var testMethods = testClass.GetMethods().Where(m => m.GetCustomAttribute<TestMethodAttribute>() != null);
    foreach (var testMethod in testMethods)
    {
        Console.WriteLine("Found test method " + testMethod.Name);
    }
}

Thanks, I'll do this if I don't find any tool soon – Mikk Aug 11 '14 at 10:14 — Mikk, Aug 11 '14 at 10:14

[TestMethod]
public void list__all_unit_tests()
{
    string sDLL = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
    string sFilePath = string.Format("{0:s}\\{1:s}.DLL", System.IO.Directory.GetCurrentDirectory(), sDLL);
    var assembly = System.Reflection.Assembly.LoadFile(sFilePath);

    var testClasses = assembly.GetTypes()
                .Where(m => m.GetCustomAttributes(typeof(TestClassAttribute),false)!=null);

    foreach (var testClass in testClasses)
    {
        var testMethods = testClass.GetMethods()
                .Where(m => m.GetCustomAttributes(typeof(TestMethodAttribute),true).Length !=0);

        foreach (var testMethod in testMethods)
        {
            Debug.Print(string.Format("class,{0:s}, method,{1:s} ", testClass.FullName , testMethod.Name));
        }
    }
}
