This page explains how integration with Bugzilla is possible in Testcollab.
To integrate Bugzilla with Test Collab, all required fields of Bugzilla's new bug form must be added in project's issue manager settings page. For example, if you have created a custom field named priority which is a required field then you must put field name and value for that field in issue manager settings page of project, else Bugzilla won't allow Test collab to submit any bug.
