Right now, the project is mostly in need of users. Someone else than me needs to have a look and see if this is any good. Please use the JIRA installation to report any issues, improvements or bugs that appear.
It may also be a good idea to drop me a line at testaco at hedemark dot net if you think Testaco is a good idea that I should use more time on, or if you feel I am pointing the project in a non-optimal direction.
Right now, the project does not cost me that much. There are some hosting costs, and the costs related to keeping my personal development rig ticking over.
If you really want to give something, buy me one of the books from my amazon.co.uk wishlist or give to your favorite charity and send me a mail about it.
