How does xUnit differ from NUnit and MSTest?

• xUnit encourages constructor injection for setup instead of [SetUp] methods.
• It uses [Fact] and [Theory] attributes for test methods, while NUnit/MSTest use

[Test] and [TestMethod].

• xUnit does not use [TestInitialize]/[TestCleanup] but favors class fixtures

and constructor/dispose patterns.

• xUnit is better integrated with .NET Core and supports parallel test execution by

default.
