What are some advanced mocking techniques in RSpec?

Advanced mocking in RSpec includes using double, instance_double, and class_double for more precise control.

Can you explain the difference between double and instance_double?

Sure! double can mock any object, while instance_double ensures the mocked object only responds to methods defined in the actual class.

How do I set expectations on a mock object?

You can set expectations using expect(mock).to receive(:method_name) to specify that a method should be called.

What about stubbing methods instead of mocking?

Stubbing is done using allow(mock).to receive(:method_name).and_return(value) to provide predefined responses.
