expect(my_spy.method).to(have_been_called)

expect(my_spy.method).to(have_been_called_with(anything, key='bar'))

expect(my_spy.method).not_to(have_been_called_with('bar', key='foo'))Times called modifiers
once
Asserts that a spy has been called exactly once.

Asserts that a spy has been called exactly n times.
expect(my_spy.method).to(have_been_called.exactly(3))

expect(my_spy.method).not_to(have_been_called.exactly(3))max
Asserts that a spy has been called maximum of n times.
expect(my_spy.method).to(have_been_called.max(2))
expect(my_spy.method).to(have_been_called_with('foo').max(2))
expect(my_spy.method).not_to(have_been_called.max(2))min
Asserts that a spy has been called minimum of n times.
expect(my_spy.method).to(have_been_called.min(2))
expect(my_spy.method).to(have_been_called_with('foo').min(2))
expect(my_spy.method).not_to(have_been_called.min(2))have_been_satisfied
Verifies that a mock calls have been satisfied.
expect(my_mock).to(have_been_satisfied)
expect(my_mock).not_to(have_been_satisfied)have_been_satisfied_in_any_order
Verifies that a mock calls have been satisfied regardless of the execution order.
expect(my_mock).to(have_been_satisfied_in_any_order)
