MSTest、NUnit、xUnit.net 属性对照表

MSTest	NUnit	xUnit.net	Comments
[TestMethod]	[Test]	[Fact]	Marks a test method.
[TestClass]	[TestFixture]	n/a	xUnit.net does not require an attribute for a test class; it looks for all test methods in all public (exported) classes in the assembly.
[ExpectedException]	[ExpectedException]	Assert.Throws Record.Exception	xUnit.net has done away with the ExpectedException attribute in favor of Assert.Throws.
[TestInitialize]	[SetUp]	Constructor	We believe that use of [SetUp]is generally bad. However, you can implement a parameterless constructor as a direct replacement.
[TestCleanup]	[TearDown]	IDisposable.Dispose	We believe that use of[TearDown] is generally bad. However, you can implementIDisposable.Dispose as a direct replacement.
[ClassInitialize]	[TestFixtureSetUp]	IUseFixture<T>	To get per-fixture setup, implement IUseFixture<T> on your test class.
[ClassCleanup]	[TestFixtureTearDown]	IUseFixture<T>	To get per-fixture teardown, implement IUseFixture<T> on your test class.
[Ignore]	[Ignore]	[Fact(Skip="reason")]	Set the Skip parameter on the[Fact] attribute to temporarily skip a test.
[Timeout]	[Timeout]	[Fact(Timeout=n)]	Set the Timeout parameter on the [Fact] attribute to cause a test to fail if it takes too long to run. Note that the timeout value for xUnit.net is in milliseconds.
[TestCategory]	[Category]	[Trait]
[TestProperty]	[Property]	[Trait]	Set arbitrary metadata on a test
[DataSource]	n/a	[Theory], [XxxData]	Theory (data-driven test).
