How can I use go-sqlmock for advanced database testing?

You can use go-sqlmock to create complex database interactions in your tests. It allows you to define expectations and simulate various scenarios.

Can you give me an example of mocking a transaction?

Sure! You can start a transaction with db.Begin() and then use sqlmock.NewRows() to define the expected results for queries within that transaction.

What about handling errors in my mock?

You can use sqlmock.ExpectExec() or sqlmock.ExpectQuery() to specify that an error should be returned when a certain query is executed.

Is it possible to mock multiple queries in one test?

Yes, you can chain multiple expectations using sqlmock.ExpectQuery() or sqlmock.ExpectExec() to simulate a series of database operations.
