expecting to have received with nil

Rspec question

having

puts x.y
x.y = nil

I want to test if this line has been executed

so something like

allow(x).to receive(:y) { 'abc' }

and then

expect(x).to have_received(:y).with nil

but with(nil) doesn't work

any suggestions?

I want to make sure y is set to nil, but I cannot just check the value since I am stubbing x.y beforehand

You are attempting to assert that 

x.y(nil)

is called.

To assert that the method y= is called with nil parameter, you'd want to use the :y= symbol instead. 

allow(x).to receive(:y=){ "xyz" }
expect(x).to have_received(:y=).with(nil)
