Is importing aggregatorV3interface in mockV3aggregator necessary?

[Fahad3242]

Can anyone explain me why import was added in MockV3Aggregator

When I removed it worked fine

THANKS IN ADVANCE

Hello @Fahad3242, We always make a contract an interface type so that we ensure that we implement all the functions and features we have planned out without forgetting anyone because the contract will not compile if you did not completely implement everything outlined in the interface. Removing the interface might lead to a scenario where you forget to implement some stuff you planned to.

Please ask questions if anything is confusing.

Thank you for the clarification. Why is it giving an error when I make the contract agginterface type

Because you did not properly import the Interface, It explicitly informed you in the error.

I just copied the mockV3agg it gave me that import error again which I faced last time when importing AggregatorV3interface. The file is exactly where the destination is written in the import line.

I will advise you to check correctly.
