[Dojo-interest] [1.02] ReferenceError: "navigator" running tests in Rhino

The built version that you get from the 1.0.2 download location (not
the -src file) is built for the browser, and not for rhino. Running
that version with rhino and DOH can produce the "navigator" issue.
Dojo can be run in the browser or in rhino, but the built versions we
put on the website are only for running in the browser. We do not
support auto-detection of the environment in the built version to cut
down on the size of dojo.js and the vast majority of users only care
about the browser version. So, for running in rhino, you will need to
get the -src download or grab the source from subversion.
DOH does not provide a simulation of the browser environment in rhino.
Instead, it runs directly in a browser. If you go to the tests
directory in each major project (like dojo or dijit), you should see a
runTests.html. Open that in the browser of your choice, and DOH will
run the tests in that browser.
The tests that run in rhino are the non-browser tests (normally the
pure JS tests). There may be a reporting issue with the number of
tests (I have not confirmed how it calculates the numbers or how it
reports what tests are run), but while it does use the same master
test file for Dojo core (dojo/tests/module.js), some tests are
excluded by checking to see if dojo.isBrowser is true. It will be
false for the rhino case, so those tests will be skipped. Also note
that while it looks like some tests in dojo/tests/module.js seem to be
included for the rhino enviroment, if you look inside the specific
tests being dojo.required, they may do the dojo.isBrowser check within
that test file.
