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).
