@yusuphjoluwasen thanks a lot for the contribution you did great job 🎉 , only one side thing i see that some test cases are missing since TabTrayState is handling more cases, could you please add them. here is a list:

• didChangePanel
• refreshTabs
• showToast
• closeAllTabs
• defaultState

This is great Thanks so much 🎉 i see only that defaultState is missing, i know you added testInitialState and it s great but default state it is a different method.
