I wrote the below code

    from flask import __version__ as flask_ver
    from sys import version as py_ver
    class MockCtx(object, ):
        resilient_parsing = False
        color = None
        def exit(self):
            return
    ctx = MockCtx()
    get_version(ctx, None, 'test')
    (out, err) = capsys.readouterr()
    assert (flask_ver in out)
    assert (py_ver in out)

What's a good function header?
