How to prepare data for testing?

Question

Software testing

There is a Moq library .
To run tests without using a database, you need to prepare test data.

var card = new Card("owner", "number", "CVV number");
paymentServiceMock.Setup(p => p.Charge(114,card)).Returns(true)

I have found several libraries that can generate test data, such as AutoFixture .
But is there really no way to automatically take the data from the database and use it?
