To get the groktoolkit tests and my company's applications to run with
Brian's zope.testbrowser+webtest branch I did the following things:

* I created a branch of zope.app.wsgi trunk [1] to which I copied the
AuthorizationMiddleware from zope.testbrowser trunk (moved there in
[2]). The three middleware components (Transaction, Authorization and
HandleErrors) are needed to make the groktoolkit tests pass. The
AuthorizationMiddleware is not available on Brian's branch, but is
available on zope.testbrowser trunk. If we can land this middleware in
zope.testbrowser, we can again remove it from zope.app.wsgi.testlayer.
In my opinion, this middleware should be part of zope.testbrowser,
because handleErrors is part of the IBrowser interface.

* The `http caller` in zope.app.wsgi.testlayer is used in
grokcore.rest. On my branch, I rewrote the http caller to use WebTest
and _APP_UNDER_TEST instead of wsgi_intercept. The import from
zope.testbrowser is bothering me; can we put the http caller in
zope.testbrowser? The http caller returns a FakeResponse instance,
which could very well be a WebTest TestResponse. The FakeResponse
wrapper is merely used to fix the current tests.

* I fixed some tests in grok and grokcore.rest to use the
WebTest-style http caller.

In order to run the tests on the groktoolkit trunk, run:

bin/buildout sources:zope.testbrowser="svn
buildout:auto-checkout="zope.testbrowser zope.app.wsgi grok
grokcore.rest" versions:WebTest=1.2.3 && bin/test-grok
