NUnit TestCase, the Data Driven Unit Test

A while back I wrote a blog post about data driven unit testing with xUnit. Back then a reader had to correct me because I did not think that NUnit had support for such things.

NUnit 2.5 added a slew of great features for authoring your own data driven unit tests. Perhaps best of all is the amazing support that ReSharper offers for the NUnit test cases.

You really should be using these amazing features when authoring your unit tests!

• NUnit on NuGet
• TestCaseAttribute
• TestCaseSourceAttribute
• CombinatorialAttribute
• SequentialAttribute

Data Driven NUnit Samples

// Here is a simple example that is the equivalent of an

// inline data attribute from xUnit.

[TestCase(1, 2, 3)]

[TestCase(2, 3, 5)]

public void SimpleSumCase(int a, int b, int expected)

{

    var actual = a + b;

    Assert.AreEqual(expected, actual);

}
