    Each test such as visualRect have a _data() function which populate the QTest data with

    setupWithNoTestData() fills QTest data with only the tests it is used by most tests.

    for the parent of the index.

    This recursive function does pretty extensive testing on the whole model in an
    effort to catch edge cases.

    This function assumes that rowCount(), columnCount() and index() work.  If they have
    a bug it will point it out, but the above tests should have already found the basic bugs
    because it is easier to figure out the problem in those tests then this one.
