Exude by Mark Seemann

Announcing Exude, an extension to xUnit.net providing test cases as first-class, programmatic citizens.

Sometimes, when writing Parameterized Tests with xUnit.net, you need to provide parameters that don't lend themselves easily to be defined as constants in [InlineData] attributes.

In Grean, we've let ourselves inspire by Mauricio Scheffer's blog post First-class tests in MbUnit, but ported the concept to xUnit.net and released it as open source.

It's called Exude and is available on GitHub and on NuGet.

Here's a small example:

[FirstClassTests]
public static IEnumerable<ITestCase> YieldFirstClassTests()
{
    yield return new TestCase(_ => Assert.Equal(1, 1));
    yield return new TestCase(_ => Assert.Equal(2, 2));
    yield return new TestCase(_ => Assert.Equal(3, 3));
}

More examples and information is available on the project site.
