Ok. I will see what I can do.

Here is a snippet from Paul's email where he told me about WebTest:

Note how verify*s are similar to assert*s. Also: "we don't want to give
up Ant 1.6.5 compatibility".

Here is a snippet from Paul's last email on the subject.

This brings us to your next question.

Currently we are only interested in asserts library. It is easy to write
them, but it would not be good if the same thing was done differently in
different projects.

What is your take on this? I mean, some generic asserts are the same for
AntUnit, WebTest, and TestLogic, but some are specific to the project.
Do you think it is worth the effort to standardize on a common asserts
library and what should be the extension mechanism?

In the future, we may be interested in AntUnit runtime (task and
listeners) as well, depending on the direction our project takes.
