Question

我正在使用VS2008开发一个我正在Mono下开始测试的项目。有很多使用VS单元测试框架编写的单元测试，有没有一个工具可以让我在Mono中运行它们？

谢谢，

根据您使用的功能，它可能很简单或很难。您可以使用命名空间/类型别名来使用另一个类库来执行断言和属性。我编写了手动运行测试的控制台程序 - 当然我可以访问vs命名空间和程序集。

对于mono - 我的建议是完全使用另一个测试系统，因为你自己使用system.reflection命名空间来加载程序集，反映属性并按需要执行，这将是乏味的。

例如：

Pseudo code:

var assembly = loadAsembly(....)
foreach(type in assembly.types) {
 if(type is static class and had method with AssemblyInitialiseAttrubute)){
    InvokeTheMethod(method);
 }
}

foreach(type in assembly.types) {
 if(type is not class and had method with TestClass)){
    InvokeTheMethod(method);
 }
 foreach(method in type with ClassinitialiseAttribute)
}
... etc

我编写了以下代码，它在Mono上运行良好。该代码不依赖于Visual Studio测试专用DLL。令人惊讶的是，它在Mone（在我的PC上的VirtualBox上运行）上运行的速度比在Visual Studio中快一些。

        public static void TestDll(string assemblyFile) {
            string symbolsFile = Path.GetFileNameWithoutExtension(assemblyFile) + ".pdb";

            byte[] assemblyBytes = File.ReadAllBytes(assemblyFile);
            byte[] symbolsBytes = File.ReadAllBytes(symbolsFile);

            Assembly assembly = Assembly.Load(assemblyBytes, symbolsBytes);

            foreach (Type type in assembly.GetTypes())
                if (HasAttribute(type, "TestClass"))
                    foreach (MethodInfo method in type.GetMethods())

                            RunTest(method);
