Hi,
For me the term *integration tests* doesn't mean *collaboration tests* + *contract tests*, but exactly what you described as *integrated tests*. According to wikipedia:
Integration testing is the phase in software testing in which individual software modules are combined and tested as a group.
So for me this is a problem with not having one naming convention and not you using the wrong word :)
I hope that your article will clarify to others what you really meant!
