Expectations

# RSpec
expect(foo).to.eq("value")
expect(foo).to_not eq("value")

# Jasmine
expect(foo).toBe("value")
expect(foo).not.toBe("value")

Mocks

# RSpec
expect(foo).to_receive(:method).twice.with('arg').and_return('value')

# Jasmine
spyOn(foo, 'method').and.returnValue('value')
expect(foo.calls.count()).toBe(2)
expect(foo.method).toHaveBeenCalledWith('arg')
