    See viewstotest.cpp for instructions on how to have your view tested with these tests.

    Each test such as visualRect have a _data() function which populate the QTest data with
    tests specified by viewstotest.cpp and any extra data needed for that particular test.

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

    There are some basic qDebug statements sprikled about that might be helpfull for
    fixing your issues.

/*!
    A model that returns an index of parent X should also return X when asking
    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.
