同时使用MSTest与NUnit进行单元测试设置

#if !NUNIT

using Microsoft.VisualStudio.TestTools.UnitTesting;

using Category = Microsoft.VisualStudio.TestTools.UnitTesting.DescriptionAttribute;

#else

using NUnit.Framework;

using TestClass = NUnit.Framework.TestFixtureAttribute;

using TestMethod = NUnit.Framework.TestAttribute;

using TestInitialize = NUnit.Framework.SetUpAttribute;

using TestCleanup = NUnit.Framework.TearDownAttribute;

using TestContext = System.Object;

using ClassCleanup = NUnit.Framework.TestFixtureTearDownAttribute;

using ClassInitialize = NUnit.Framework.TestFixtureSetUpAttribute;

#endif
