Here is my plan. First, we should resolve issue22236. Otherwise some tests will be run with default root created with old "wantobjects" value. Then we should introduce new test resource name as in Lilo's first patch (but "wantobjects" is not correct name, "testallwantobjectsvalues" is more correct but is too long). Then we should add the load_tests() function in every test file which will generate new test classes for every wantobjects value (0, 1 and 2 if issue22214 will be applied) when this resource is enabled.

Any propositions about new resource name?

As for rearranging the tkinter tests, lets discuss this in separate issue. It looks orthogonal to this issue.
