Need Feedback: RequiredAddinAttribute

[Charlie Poole]

Hi All,

The 2.5 Alpha 3 release of NUnit includes the RequiredAddinAttribute,
used to indicate that a test expects a particular addin to be installed.
This is intended to give a failure if the addin is not present.

As explained at http://nunit.org/?p=requiredAddin&r=2.5 the attribute
will not always be seen by NUnit when it is placed on a method or
a class. I'm thinking of disallowing it on methods and classes in
the next release for that reason. What do you think?

Charlie

you may get it more than once. This seems preferable to cross-posting.

I don't have strong opinions on this topic, but I do have a use case
to consider in the conversation.

Suppose that you distribute your tests with your program to be run
after install. If your tests require that a particular Addin be
installed, it would be nice to have an explicit message that told the
customer why the tests didn't pass (Addin X Required by NUnit) instead
of just having hundreds of tests fail for reasons that might not be
immediately clear. Possibly worse yet, all the tests pass and the user
thinks all is well because NUnit doesn't recognize the test classes as
even being tests without the Addin present.

Hi Kelly,

Good point! In such a situation, I'd definitely want to
use the attribute.

Thanks for your feedback, which came on several lists as well as direct to
me.

I have now limited the attribute to use at the assembly level, since that
works
exactly as one might expect.
