Pressing tab key on tabs

[cheeaun]

When I press the 'tab' key, the focus ring should shift to the next tab. It may not open the tab but just have a focus ring on it. Then if I press the 'Enter' key, opens that focused tab.

That's not actually the correct behavior. See http://www.w3.org/TR/2009/WD-wai-aria-practices-20091215/#tabpanel for suggested keyboard usage of a Tab Panel.
