If you had a look at zope.testbrowser/setup.py, you'd notice

     extras_require = dict(
         test = ['zope.interface',
                 'zope.schema',
                 'zope.app.component',
                 'zope.app.folder',
                 'zope.app.testing',
                 'zope.app.zcmlfiles',
                 'zope.app.securitypolicy',
                ],
         ),
