What are the differences between MSTest and other frameworks like NUnit and xUnit?

• MSTest is Microsoft's official framework; NUnit and xUnit are community-driven.
• MSTest uses [TestClass] and [TestMethod] attributes; xUnit uses [Fact],

NUnit uses [Test].

• MSTest has less flexibility in data-driven tests compared to NUnit’s [TestCase] and

xUnit’s [Theory].

• xUnit promotes constructor-based setup, MSTest uses [TestInitialize].
