Judah,
I don't see a way that I particularly like. How about we make a new way?
[TestFixture]
public class ExampleTest
{
[ParameterProvider("ThisIsAKey")]
public Parameters[] MyParameters()
{
List<Parameters> ParametersList = new List<Parameters>();
ParametersList.Add(typeof(ArgumentNullException), null, bar, baz)
ParametersList.Add(typeof(ArgumentNullException), foo, null, baz)
ParametersList.Add(typeof(ArgumentNullException), foo, bar, null)
return ParametersList.ToArray();
}
[ParameterizedTest("ThisIsAKey")]
public void MyTest(Foo foo, Bar bar, Baz baz)
dar.Fobnicate(foo, bar, baz);
}
I am not very happy with the key part. What do you think?
Smiles,
Jay
