Question

I’m using Visual studio (sometimes resharper) to run my unit test.

I heard about NUnit, but I don’t know many things about it…

Should I care about it ? Can it offer something better than visual studio?

Should I Use NUnit and why?

Answer 1

NUnit has few advantages over MS-Test

1. Suite attribute – can aggregate tests and execute them separately (useful for large projects with fast and slow tests for example)
2. Readable Assert method, e.g. Assert.AreEqual(expected, actual) vs Assert.That(actual, Is.EqualTo(expected))
3. NUnit has frequent version updates – MS-Test has only one per VS version.
4. Many integrated runners including Resharper and TestDriven.NET
5. Expected exception message assertion – can be done using attribute in NUnit but must be done using Try-Catch in MS-Test
6. [TestCase]! NUnit allows for parameter-ized tests.
